Fresh shrimps were dipped in 0, 1.0% and 2.0% (v/v) lactic acid alone and their combined application with 0.04 (g/L/kg) nisin solution for 10 min. Total plate counts of aerobic bacteria (TPCs), Psychrotrophic counts, population of Pseudomonas spp., H2S producing bacteria and Lactic acid bacteria (LAB) on shrimps were determined during storage at 4 °C. The results indicated that total plate counts were 2.91 and 2.63 log CFU/g higher on untreated shrimps after 7 and 14 days of storage, respectively, than on shrimps treated with 2.0% lactic acid combined with 0.04 (g/L/kg) nisin. Both concentrations of lactic acid indicated significant reduction on Pseudomonas counts during storage, while 2.0% lactic acid combined with nisin indicated the highest reduction. In addition, H2S producing bacteria were more sensitive to high concentration of lactic acid combined with nisin during storage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Shrimp" title="Shrimp">Shrimp</a>, <a href="https://publications.waset.org/search?q=lactic%20acid" title=" lactic acid"> lactic acid</a>, <a href="https://publications.waset.org/search?q=nisin" title=" nisin"> nisin</a>, <a href="https://publications.waset.org/search?q=spoilage%20bacteria" title=" spoilage bacteria"> spoilage bacteria</a> </p> <a href="https://publications.waset.org/6489/inhibitory-effect-of-lactic-acid-and-nisin-on-bacterial-spoilage-of-chilled-shrimp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/6489/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/6489/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/6489/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/6489/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/6489/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/6489/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/6489/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/6489/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/6489/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/6489/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/6489.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2461</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">760</span> Assessment of Vermiculite Concrete Containing Bio-Polymer Aggregate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Aliakbar%20Sayadi">Aliakbar Sayadi</a>, <a href="https://publications.waset.org/search?q=Thomas%20R.%20Neitzert"> Thomas R.

Test results indicated that the inclusion of poly-lactic acid decreased the PH value of concrete and all the poly-lactic acid particles were dissolved due to the formation of sodium lactide and lactide oligomers when subjected to the high alkaline environment of concrete. In addition, an increase in thermal conductivity value of concrete was observed as the ratio of poly-lactic acid increased. Moreover, a set of equations was proposed to estimate the water-cement ratio, cement content and water absorption ratio of concrete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Poly-lactic%20acid" title="Poly-lactic acid">Poly-lactic acid</a>, <a href="https://publications.waset.org/search?q=PLA" title=" PLA"> PLA</a>, <a href="https://publications.waset.org/search?q=vermiculite" title=" vermiculite"> vermiculite</a>, <a href="https://publications.waset.org/search?q=concrete" title=" concrete"> concrete</a>, <a href="https://publications.waset.org/search?q=eco-friendly" title=" eco-friendly"> eco-friendly</a>, <a href="https://publications.waset.org/search?q=mechanical%20properties." title=" mechanical properties."> mechanical properties.</a> </p> <a href="https://publications.waset.org/10005364/assessment-of-vermiculite-concrete-containing-bio-polymer-aggregate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10005364/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10005364/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10005364/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10005364/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10005364/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10005364/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10005364/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10005364/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10005364/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10005364/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10005364.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1798</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">759</span> Utilization of Sugarcane Bagasses for Lactic Acid Production by acid Hydrolysis and Fermentation using Lactobacillus sp</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Woranart%20Jonglertjunya">Woranart Jonglertjunya</a>, <a href="https://publications.waset.org/search?q=Nattawadee%20Pranrawang"> Nattawadee Pranrawang</a>, <a href="https://publications.waset.org/search?q=Nuanyai%20Phookongka"> Nuanyai Phookongka</a>, <a href="https://publications.waset.org/search?q=Thanasak%20Sridangtip"> Thanasak Sridangtip</a>, <a href="https://publications.waset.org/search?q=Watthana%20Sawedrungreang">Watthana Sawedrungreang</a>, <a href="https://publications.waset.org/search?q=Chularat%20Krongtaew"> Chularat Krongtaew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Sugarcane bagasses are one of the most extensively used agricultural residues. Using acid hydrolysis and fermentation, conversion of sugarcane bagasses to lactic acid was technically and economically feasible. This research was concerned with the solubility of lignin in ammonium hydroxide, acid hydrolysis and lactic acid fermentation by Lactococcus lactis, Lactobacillus delbrueckii, Lactobacillus plantarum, and Lactobacillus casei. The lignin extraction results for different ammonium hydroxide concentrations showed that 10 % (v/v) NH4OH was favorable to lignin dissolution. Acid hydrolysis can be enhanced with increasing acid concentration and reaction temperature. The optimum glucose and xylose concentrations occurred at 121 ○C for 1 hour hydrolysis time in 10% sulphuric acid solution were 32 and 11 g/l, respectively. In order to investigate the significance of medium composition on lactic acid production, experiments were undertaken whereby a culture of Lactococcus lactis was grown under various glucose, peptone, yeast extract and xylose concentrations. The optimum medium was composed of 5 g/l glucose, 2.5 g/l xylose, 10 g/l peptone and 5 g/l yeast extract. Lactococcus lactis represents the most efficient for lactic acid production amongst those considered. The lactic acid fermentation by Lactococcus lactis after 72 hours gave the highest yield of 1.4 (g lactic acid per g reducing sugar).</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=sugarcane%20bagasses" title="sugarcane bagasses">sugarcane bagasses</a>, <a href="https://publications.waset.org/search?q=acid%20hydrolysis" title=" acid hydrolysis"> acid hydrolysis</a>, <a href="https://publications.waset.org/search?q=lactic%20acid" title=" lactic acid"> lactic acid</a>, <a href="https://publications.waset.org/search?q=fermentation" title=" fermentation"> fermentation</a> </p> <a href="https://publications.waset.org/11149/utilization-of-sugarcane-bagasses-for-lactic-acid-production-by-acid-hydrolysis-and-fermentation-using-lactobacillus-sp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/11149/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/11149/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/11149/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/11149/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/11149/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/11149/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/11149/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/11149/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/11149/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/11149/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/11149.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">3517</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">758</span> Biocompatible Ionic Liquids in Liquid – Liquid Extraction of Lactic Acid: A Comparative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Konstantza%20Tonova">Konstantza Tonova</a>, <a href="https://publications.waset.org/search?q=Ivan%20Svinyarov"> Ivan Svinyarov</a>, <a href="https://publications.waset.org/search?q=Milen%20G.%20Bogdanov"> Milen G.

For conversion of biomass, glucose is a particularly popular model compound for cellulose, or more generally for biomass. The present study takes a different approach by employing lactic acid as the model compound for cellulose. Since lactic acid and glucose have identical elemental composition, they are expected to produce similar results as they go through the conversion process. In the current study, lactic acid was thermochemically converted to assess its reactivity and reaction mechanism in subcritical and supercritical water, by using a 16-ml autoclave reactor. The major operating parameters investigated include: The reaction temperature, from 673 to 873 K, the reaction pressure, 10 and 25 MPa, the dosage of oxidizing agent, 0 and 0.5 chemical oxygen demand, and the concentration of lactic acid in the feed, 0.5 and 1.0 M.

Due to the nature of n-butanol that is partially miscible in water, incorporation of aqueous solution into organic phase was observed in the extraction with large organic-to-aqueous volume ratio.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Lactic%20acid" title="Lactic acid">Lactic acid</a>, <a href="https://publications.waset.org/search?q=liquid-liquid%20extraction" title=" liquid-liquid extraction"> liquid-liquid extraction</a>, <a href="https://publications.waset.org/search?q=n-Butanol" title=" n-Butanol"> n-Butanol</a>, <a href="https://publications.waset.org/search?q=Solvating%20extractant." title=" Solvating extractant."> Solvating extractant.</a> </p> <a href="https://publications.waset.org/7085/n-butanol-as-an-extractant-for-lactic-acid-recovery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/7085/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/7085/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/7085/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/7085/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/7085/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/7085/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/7085/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/7085/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/7085/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/7085/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/7085.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">3171</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">755</span> Utilization of Wheat Bran as Bed Material in Solid State Bacterial Production of Lactic Acid with Various Nitrogen Sources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=U.K.Ghosh">U.K.Ghosh</a>, <a href="https://publications.waset.org/search?q=M.K.Ghosh"> M.K.Ghosh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present experimental investigation brings about a comparative study of lactic acid production by pure strains of Lactobacilli (1) L. delbreuckii (NCIM2025), (2) L. pentosus (NCIM 2912), (3) Lactobacillus sp.(NCIM 2734, (4) Lactobacillus sp.

Despite nutritional benefits of whole flour, concentration of some undesirable components such as phytic acid is higher than white flour. In this study, effect of several lactic acid bacteria sourdough on Toast bread is investigated. Sourdough from lactic acid bacteria (Lb. plantarum, Lb. reuteri) with different dough yield (250 and 300) is made and incubated at 30°C for 20 hour, then added to dough in the ratio of 10, 20 and 30% replacement. Breads that supplemented with Lb. plantarum sourdough had lower phytic acid. Higher replacement of sourdough and higher DY cause higher decrease in phytic acid content. Sourdough from Lb. plantarum, DY = 300 and 30% replacement cause the highest decrease in phytic acid content (49.63 mg/100g). As indicated by panelists, Lb. reuteri sourdough can present the greatest effect on overall quality score of the breads. DY reduction cause a decrease in bread quality score. Sensory score of Toast bread is 81.71 in the samples that treated with Lb. reuteri sourdough with DY = 250 and 20% replacement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Phytic%20Acid" title="Phytic Acid">Phytic Acid</a>, <a href="https://publications.waset.org/search?q=Sourdough" title=" Sourdough"> Sourdough</a>, <a href="https://publications.waset.org/search?q=Toast%20Bread" title=" Toast Bread"> Toast Bread</a>, <a href="https://publications.waset.org/search?q=Whole%20Wheat%20Flour" title=" Whole Wheat Flour"> Whole Wheat Flour</a>, <a href="https://publications.waset.org/search?q=Lactic%20Acid%20Bacteria." title=" Lactic Acid Bacteria."> Lactic Acid Bacteria.</a> </p> <a href="https://publications.waset.org/14388/effect-of-different-lactic-acid-bacteria-on-phytic-acid-content-and-quality-of-whole-wheat-toast-bread" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/14388/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/14388/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/14388/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/14388/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/14388/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/14388/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/14388/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/14388/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/14388/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/14388/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/14388.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2943</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">752</span> Poly(Lactic Acid) Based Flexible Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Fathilah%20binti%20Ali">Fathilah binti Ali</a>, <a href="https://publications.waset.org/search?q=Jamarosliza%20Jamaluddin"> Jamarosliza Jamaluddin</a>, <a href="https://publications.waset.org/search?q=Arun%20Kumar%20Upadhyay"> Arun Kumar Upadhyay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Poly(lactic acid) (PLA) is a biodegradable polymer which has good mechanical properties, however, its brittleness limits its usage especially in packaging materials.

For this purpose, PLA based polyurethane must have good strength and flexibility. Therefore, polycaprolactone which has better flexibility were prepared with PLA.

Germinated native black rice juice was inoculated with a 24-h old lactic culture and incubated at 30 °C for 72 hours. Changes in pH, acidity, total soluble solid, and viable cell counts during fermentation under controlled conditions at 0-h, 24-h, 48-h, and 72-h fermentations were evaluated. The study found out that the change in pH and total soluble solid of probiotic germinated black rice juice significantly (p ≤ 0.05) decreased at 72-h fermentation (5.67±0.12 to 2.86±0.04 and 7.00±0.00 to 6.40±0.00 ºbrix at 0-h and 72-h fermentations, respectively).

In addition, the free radical scavenging capacity assayed by DPPH method also showed that the IC<sub>50</sub> values were significantly (p≤0.05) higher than the control (147.71±0.96 and 202.55±1.24 mg/ml, respectively). After 4 weeks of cold storage at 4 °C, the viable cell counts of lactic acid bacteria reduced to 1.37 x 10<sup>6</sup> CFU/ml. In conclusion, fermented germinated native black rice juice could be served as a healthy beverage for vegans and people who are allergic to cow milk products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Germinated%20native%20black%20rice" title="Germinated native black rice">Germinated native black rice</a>, <a href="https://publications.waset.org/search?q=probiotic" title=" probiotic"> probiotic</a>, <a href="https://publications.waset.org/search?q=lactic%20acid%20bacteria" title=" lactic acid bacteria"> lactic acid bacteria</a>, <a href="https://publications.waset.org/search?q=Lactobacillus%20casei." title=" Lactobacillus casei."> Lactobacillus casei.</a> </p> <a href="https://publications.waset.org/10005393/fermentation-of-germinated-native-black-rice-milk-mixture-by-probiotic-lactic-acid-bacteria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10005393/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10005393/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10005393/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10005393/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10005393/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10005393/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10005393/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10005393/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10005393/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10005393/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10005393.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1642</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">749</span> Study of Biocomposites Based of Poly(Lactic Acid) and Olive Husk Flour</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Samra%20Isadounene">Samra Isadounene</a>, <a href="https://publications.waset.org/search?q=Amar%20Boukerrou"> Amar Boukerrou</a>, <a href="https://publications.waset.org/search?q=Dalila%20Hammiche"> Dalila Hammiche </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, the composites were prepared with poly(lactic acid) (PLA) and olive husk flour (OHF) with different percentages (10, 20 and 30%) using extrusion method followed by injection molding.

Tensile strength and elongation at break of composites showed a decreasing trend with increasing fiber content. On the other hand, Young modulus and storage modulus were increased. The addition of OHF resulted in a decrease in thermal stability of composites. The presence of OHF led to an increase in percentage of crystallinity (Xc) of PLA matrix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Biopolymers" title="Biopolymers">Biopolymers</a>, <a href="https://publications.waset.org/search?q=composites" title=" composites"> composites</a>, <a href="https://publications.waset.org/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/search?q=poly%28lactic%20acid%29." title=" poly(lactic acid)."> poly(lactic acid).</a> </p> <a href="https://publications.waset.org/10007716/study-of-biocomposites-based-of-polylactic-acid-and-olive-husk-flour" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10007716/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10007716/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10007716/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10007716/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10007716/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10007716/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10007716/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10007716/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10007716/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10007716/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10007716.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1005</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">748</span> Antibacterial Activity of Lactic Acid Bacteria Isolated from Table Olives against Skin Pathogens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=M.%20Shafighi">M.

Among the composites, untreated 0.5 wt % MWCNTs and acid-treated 1.0 wt% MWCNTs reinforced PLA show the tensile strength and modulus values higher than the others. These two samples along with pure PLA exhibit the stable orthorhombic α-form, whilst other samples reveal the less stable orthorhombic β-form, as demonstrated by X-ray diffraction study. Differential scanning calorimetry reveals the evolution of the mentioned different phases by controlled cooling and discloses an enhancement of PLA crystallization by nanotubes incorporation. Thermogravimetric analysis shows that the MWCNTs loaded sample degraded faster than PLA. Surface resistivity of the nanocomposites is found to be dropped drastically by a factor of 1013 with a low loading of MWCNTs (1.5 wt%). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Crystallization" title="Crystallization">Crystallization</a>, <a href="https://publications.waset.org/search?q=multi-walled%20carbon%20nanotubes" title=" multi-walled carbon nanotubes"> multi-walled carbon nanotubes</a>, <a href="https://publications.waset.org/search?q=nanocomposites" title=" nanocomposites"> nanocomposites</a>, <a href="https://publications.waset.org/search?q=Poly%20%28lactic%20acid%29." title=" Poly (lactic acid)."> Poly (lactic acid).</a> </p> <a href="https://publications.waset.org/13702/characterization-of-biodegradable-nanocomposites-with-poly-lactic-acid-and-multi-walled-carbon-nanotubes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/13702/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/13702/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/13702/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/13702/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/13702/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/13702/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/13702/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/13702/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/13702/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/13702/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/13702.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2603</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">746</span> Effect of Lactic Acid Bacteria Inoculant on Fermentation Quality of Sweet Sorghum Silage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Azizza%20Mala">Azizza Mala</a>, <a href="https://publications.waset.org/search?q=Babo%20Fadlalla"> Babo Fadlalla</a>, <a href="https://publications.waset.org/search?q=Elnour%20Mohamed"> Elnour Mohamed</a>, <a href="https://publications.waset.org/search?q=Siran%20Wang"> Siran Wang</a>, <a href="https://publications.waset.org/search?q=Junfeng%20Li"> Junfeng Li</a>, <a href="https://publications.waset.org/search?q=Tao%20Shao"> Tao Shao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Sweet sorghum is considered one of the best plants for silage production and is now a more important feed crop in many countries worldwide. It is simple to ensile because of its high water-soluble carbohydrates (WSC) concentration and low buffer capacity. This study investigated the effect of adding Pediococcus acidilactici AZZ5 and Lactobacillus plantarum AZZ4 isolated from elephant grass on the fermentation quality of sweet sorghum silage. One commercial bacteria Lactobacillus Plantarum, Ecosyl MTD/1(CB), and two strains were used as additives Pediococcus acidilactici (AZZ5), Lactobacillus plantarum subsp. Plantarum (AZZ4) at 6 log colony forming units (cfu)/g of fresh sweet sorghum grass in laboratory silos (1000 g). After 15, 30, and 60 days, the silos for each treatment were opened. All of the isolated strains enhanced the silage quality of sweet sorghum silage compared to the control, as evidenced by significantly (P < 0.05) lower ammonia nitrogen (NH3-N) content and undesirable microbial counts, as well as greater lactic acid (LA) contents and lactic acid/acetic acid (LA/AA) ratios. In addition, AZZ4 performed better than all other inoculants during ensiling, as evidenced by a significant (P < 0.05) reduction in pH and ammonia-N contents and a significant increase in LA contents.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Fermentation" title="Fermentation">Fermentation</a>, <a href="https://publications.waset.org/search?q=Lactobacillus%20plantarum" title=" Lactobacillus plantarum"> Lactobacillus plantarum</a>, <a href="https://publications.waset.org/search?q=lactic%20acid%20bacteria" title=" lactic acid bacteria"> lactic acid bacteria</a>, <a href="https://publications.waset.org/search?q=Pediococcus%20acidilactic" title=" Pediococcus acidilactic"> Pediococcus acidilactic</a>, <a href="https://publications.waset.org/search?q=sweet%20sorghum." title=" sweet sorghum."> sweet sorghum.</a> </p> <a href="https://publications.waset.org/10013454/effect-of-lactic-acid-bacteria-inoculant-on-fermentation-quality-of-sweet-sorghum-silage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10013454/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10013454/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10013454/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10013454/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10013454/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10013454/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10013454/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10013454/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10013454/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10013454/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10013454.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">208</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">745</span> Mathematical Modeling for Continuous Reactive Extrusion of Poly Lactic Acid formation by Ring Opening Polymerization Considering Metal/Organic Catalyst and Alternative Energies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Satya%20P.%20Dubey">Satya P.

PLA can be polymerized from monomers (Lactide or Lactic acid) obtained by fermentation processes from renewable sources such as corn starch or sugarcane. For PLA synthesis, ring opening polymerization (ROP) of Lactide monomer is one of the preferred methods. In the literature, the technique mainly developed for ROP of PLA is based on metal/bimetallic catalyst (Sn, Zn and Al) or other organic catalysts in suitable solvent. However, the PLA synthesized using such catalysts may contain trace elements of the catalyst which may cause toxicity.

Sodium hydroxide (at 0.1, 0.5, and 1.0 M concentrations) and distilled water were used as anolyte, while lactic acid (at 0.01, 0.1, and 0.5 M concentrations), ammonium citrate (also at 0.01, 0.1, and 0.5 M concentrations) and distilled water were used as catholyte. A continuous voltage application (1.0 VDC/cm) was employed for 240 hours for each experiment. The copper content of the catholyte was determined at the end of the 240-hour period. Optimization was carried out with a Response Surface Methodology - Optimal Design, including F test, and multiple comparison method, to determine which pair of anolyte-catholyte was the most significant for the removal efficiency. "1.0 M NaOH" was found to be the most significant anolyte while it was established that lactic acid was the most significant type of catholyte to be used for the most successful electrokinetic experiments. Concentrations of lactic acid should be at the range of 0.1 M to 0.5 M to achieve maximum percent removal values.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Electrokinetic%20remediation" title="Electrokinetic remediation">Electrokinetic remediation</a>, <a href="https://publications.waset.org/search?q=copper%20contamination" title=" copper contamination"> copper contamination</a>, <a href="https://publications.waset.org/search?q=heavy%20metal%20contamination" title=" heavy metal contamination"> heavy metal contamination</a>, <a href="https://publications.waset.org/search?q=soil%20remediation" title=" soil remediation"> soil remediation</a> </p> <a href="https://publications.waset.org/11188/electroremediation-of-cu-contaminated-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/11188/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/11188/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/11188/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/11188/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/11188/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/11188/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/11188/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/11188/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/11188/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/11188/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/11188.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1727</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">743</span> Preliminary Study of Fermented Pickle of Tabah Bamboo Shoot (Gigantochloa nigrociliata (Buese) Kurz)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Luh%20Putu%20T.%20Darmayanti">Luh Putu T.

Application of lactic acid bacteria (LAB) for the removal of toxic and heavy metals from water has been reported. This study was performed in order to isolate and characterize the Asresistant LAB from mud and sludge samples for using as efficient As uptaking probiotic. Isolation of As-resistant LAB colonies was performed by spread plate technique using bromocresol purple impregnated-MRS (BP-MRS) agar media provided with As @ 50 μg/ml. Isolated LAB were employed for probiotic characterization process, acid and bile tolerance, lactic acid production, antibacterial activity and antibiotic tolerance assays. After As-resistant and removal characterizations, the LAB were identified using 16S rDNA sequencing. A total of 103 isolates were identified as As-resistant strains of LAB. The survival of 6 strains (As99-1, As100-2, As101-3, As102-4, As105-7, and As112-9) was found after passing through the sequential probiotic characterizations. Resistant pattern pronounced hollow zones at As concentration >2000 μg/ml in As99-1, As100-2, and As101-3 LAB strains, whereas it was found at ~1000 μg/ml in rest 3 strains. Among 6 strains, the As uptake efficiency of As102-4 (0.006 μg/h/mg wet weight of cell) was higher (17 – 209%) compared to remaining LAB. 16S rDNA sequencing data of 3 (As99- 1, As100-2, and As101-3) and 3 (As102-4, As105-7, and As112-9) LAB strains clearly showed 97 to 99% (340 bp) homology to Pediococcus dextrinicus and Pediococcus acidilactici, respectively. Though, there was no correlation between the metal resistant and removal efficiency of LAB examined but identified elevated As removing LAB would probably be a potential As uptaking probiotic agent. Since present experiment concerned with only As removal from pure water, As removal and removal mechanism in natural condition of intestinal milieu should be assessed in future studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Lactic%20acid%20bacteria" title="Lactic acid bacteria">Lactic acid bacteria</a>, <a href="https://publications.waset.org/search?q=As-resistant" title=" As-resistant"> As-resistant</a>, <a href="https://publications.waset.org/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/search?q=Pediococcus%20sp." title=" Pediococcus sp."> Pediococcus sp.</a>, <a href="https://publications.waset.org/search?q=As%20removal%20probiotic." title=" As removal probiotic."> As removal probiotic.</a> </p> <a href="https://publications.waset.org/14465/isolation-and-probiotic-characterization-of-arsenic-resistant-lactic-acid-bacteria-for-uptaking-arsenic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/14465/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/14465/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/14465/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/14465/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/14465/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/14465/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/14465/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/14465/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/14465/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/14465/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/14465.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2734</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">741</span> Anti-Aging Effects of Retinol and Alpha Hydroxy Acid on Elastin Fibers of Artificially Photo-Aged Human Dermal Fibroblast Cell Lines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=M.%20Jarrar">M.

Ultra-violet radiations (UV), diet, smoking and personal habits are the most common environmental factors that affect skin aging. Fat contents and fibrous proteins as collagen and elastin are core internal structural components. The direct influence of UV on elastin integrity and health is central on aging of skin especially by time. The deposition of abnormal elastic material is a major marker in a photo-aged skin. Searching for compounds that may protect against cutaneous photodamage is exceedingly valued. Retinoids and alpha hydroxy acids have been endorsed by some researchers as possible candidates for protecting and or repairing the effect of UV damaged skin. For consolidating a better system of anti- and protective effects of such anti-aging agents, we evaluated the combinatory effects of various dosages of lactic acid and retinol on the dermal fibroblast’s elastin levels exposed to UV. The UV exposed cells showed significant reduction in the elastin levels. A combination of drugs with a higher concentration of lactic acid (30 -35 mM) and a lower concentration of retinol (10-15mg/mL) showed to work better in maintaining elastin concentration in UV exposed cells. We assume this preservation could be the result of increased tropo-elastin gene expression stimulated by retinol whereas lactic acid probably repaired the UV irradiated damage by enhancing the amount and integrity of the elastin fibers.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Alpha%20Hydroxy%20Acid" title="Alpha Hydroxy Acid">Alpha Hydroxy Acid</a>, <a href="https://publications.waset.org/search?q=Elastin" title=" Elastin"> Elastin</a>, <a href="https://publications.waset.org/search?q=Retinol" title=" Retinol"> Retinol</a>, <a href="https://publications.waset.org/search?q=Ultraviolet%0D%0Aradiations." title=" Ultraviolet radiations."> Ultraviolet radiations.</a> </p> <a href="https://publications.waset.org/10000933/anti-aging-effects-of-retinol-and-alpha-hydroxy-acid-on-elastin-fibers-of-artificially-photo-aged-human-dermal-fibroblast-cell-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10000933/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10000933/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10000933/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10000933/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10000933/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10000933/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10000933/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10000933/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10000933/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10000933/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10000933.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">3094</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">740</span> The Impact of the Cell-Free Solution of Lactic Acid Bacteria on Cadaverine Production by Listeria monocytogenes and Staphylococcus aureus in Lysine-Decarboxylase Broth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Fatih%20%C3%96zogul">Fatih Özogul</a>, <a href="https://publications.waset.org/search?q=Nurten%20Toy"> Nurten Toy</a>, <a href="https://publications.waset.org/search?q=Yesim%20%C3%96zogul"> Yesim Özogul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The influences of cell-free solutions (CFSs) of lactic acid bacteria (LAB) on cadaverine and other biogenic amines production by Listeria monocytogenes and Staphylococcus aureus were investigated in lysine decarboxylase broth (LDB) using HPLC.

Although biodegradation of chloroethenes occur in this zone, it is a slow process and a remediation strategy is needed. The aim of this study is to demonstrate that combined strategy of biostimulation and <em>in situ</em> chemical reduction (ISCR) is more efficient than the two separated strategies. Four different microcosm experiments with sediment and groundwater of a selected field site where an aged pool exists at the bottom of a transition zone were designed under i) natural conditions, ii) biostimulation with lactic acid, iii) ISCR with zero-value iron (ZVI) and under iv) a combined strategy with lactic acid and ZVI. Biotic and abiotic dehalogenation, terminal electron acceptor processes and evolution of microbial communities were determined for each experiment. The main results were: i) reductive dehalogenation of PCE-pools occurs under sulfate-reducing conditions; ii) biostimulation with lactic acid supports more pronounced reductive dehalogenation of PCE and trichloroethene (TCE), but results in an accumulation of 1,2-cis-dichloroethene (cDCE); iii) ISCR with ZVI produces a sustained dehalogenation of PCE and its metabolites iv) combined strategy of biostimulation and ISCR results in a fast dehalogenation of PCE and TCE and a sustained dehalogenation of cisDCE. These findings suggest that biostimulation and ISCR with ZVI are the most suitable strategies for a complete reductive dehalogenation of PCE-pools in the transition zone and further to enable the dissolution of dense non-aqueous phase liquids.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Aged%20PCE-pool" title="Aged PCE-pool">Aged PCE-pool</a>, <a href="https://publications.waset.org/search?q=anaerobic%20microcosm%20experiment" title=" anaerobic microcosm experiment"> anaerobic microcosm experiment</a>, <a href="https://publications.waset.org/search?q=biostimulation" title=" biostimulation"> biostimulation</a>, <a href="https://publications.waset.org/search?q=in%20situ%20chemical%20reduction" title=" in situ chemical reduction"> in situ chemical reduction</a>, <a href="https://publications.waset.org/search?q=natural%20attenuation." title=" natural attenuation."> natural attenuation.</a> </p> <a href="https://publications.waset.org/10010222/bioremediation-potential-in-recalcitrant-areas-of-pce-in-alluvial-fan-deposits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10010222/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10010222/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10010222/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10010222/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10010222/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10010222/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10010222/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10010222/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10010222/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10010222/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10010222.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">734</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">738</span> The Dynamics of Microorganisms in Dried Yogurt Storages at Different Temperatures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jaruwan%20Chutrtong">Jaruwan Chutrtong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Yoghurt is a fermented milk product. The process of making yogurt involves fermenting milk with live and active bacterial cultures by adding bacteria directly to the dairy product. It is usually made with a culture of <em>Lactobacillus </em>sp<em>. (L. acidophilus</em> or <em>L</em>. <em>bulgaricus)</em> and <em>Streptococcus thermophilus</em>.

When purchasing yogurt, consumers should always check the label for live cultures. Yoghurt must keep in refrigerator at 4°C for up to ten days. After this amount of time, the cultures often become weak. This research studied freezing dry yogurt storage by monitoring on the survival of microorganisms when stored at different temperatures. At 30<sup>0</sup>C, representative room temperature of country in equator zone, number of lactic acid bacteria reduced 4 log cycles in 10 week. At 40<sup>0</sup>C, representative temperature in summer of country in equator zone, number of lactic acid bacteria also dropped 4 log cycle in 10 week, similar as storage at 30<sup>0</sup>C. But drying yogurt storage at 40<sup>0</sup>C couldn’t reformed to be good character yogurt as good as storage at 40<sup>0</sup>C only 4 week storage too.

Thirty autochthonous lactic acid bacteria isolated previously, belonging to the genera: <i>Lactobacillus</i>, <i>Carnobacterium</i>, <i>Lactococcus</i>, <i>Vagococcus</i>, <i>Streptococcus</i>, and <i>Pediococcus</i>, have been screened by an agar spot test and a well diffusion assay against Gram-positive and Gram-negative harmful bacteria: <i>Bacillus cereus</i>, <i>Bacillus subtilis </i>ATCC 6633, <i>Escherichia coli </i>ATCC 8739, <i>Salmonella </i><i>typhimurium </i>ATCC 14028, <i>Staphylococcus aureus </i>ATCC 6538, and <i>Pseudomonas aeruginosa</i> under conditions means to reduce lactic acid and hydrogen peroxide effect to select bacteria with high bacteriocinogenic potential. Furthermore, crude bacteriocins semiquantification and heat sensitivity to different temperatures (80, 95, 110°C, and 121°C) were performed. Another exploratory test concerning the response of <i>St. aureus </i>ATCC 6538 to the presence of crude bacteriocins was realized. It has been observed by the agar spot test that fifteen candidates were active toward Gram-positive targets strains. The secondary screening demonstrated an antagonistic activity oriented only against <i>St. aureus </i>ATCC 6538, leading to the selection of five isolates: L<sub>m14</sub>, L<sub>m21</sub>, L<sub>m23</sub>, L<sub>m24</sub>, and L<sub>m25</sub> with a larger inhibition zone compared to the others. The ANOVA statistical analysis reveals a small variation of repeatability: L<sub>m21</sub>: 0.56%, L<sub>m23</sub>: 0%, L<sub>m25</sub>: 1.67%, L<sub>m14</sub>: 1.88%, L<sub>m24</sub>: 2.14%. Conversely, slight variation was reported in terms of inhibition diameters: 9.58± 0.40, 9.83± 0.46 and 10.16± 0.24 8.5 ± 0.40 10 mm for, L<sub>m21</sub>, L<sub>m23</sub>, L<sub>m25</sub>, L<sub>m14</sub>and L<sub>m24</sub>, indicating that the observed potential showed a heterogeneous distribution (BMS = 0.383, WMS = 0.117). The repeatability coefficient calculated displayed 7.35%. As for the bacteriocins semiquantification, the five samples exhibited production amounts about 4.16 for L<sub>m21</sub>, L<sub>m23</sub>, L<sub>m25</sub> and 2.08 AU/ml for L<sub>m14</sub>, L<sub>m24</sub>. Concerning the sensitivity the crude bacteriocins were fully insensitive to heat inactivation, until 121°C, they preserved the same inhibition diameter. As to, kinetic of growth , the µmax showed reductions in pathogens load for L<sub>m21</sub>, L<sub>m23</sub>, L<sub>m25</sub>, L<sub>m14</sub>, L<sub>m24</sub> of about 42.92%, 84.12%, 88.55%, 54.95%, 29.97% in the second trails. Inversely, this pathogen growth after five hours displayed differences of 79.45%, 12.64%, 11.82%, 87.88%, 85.66% in the second trails, compared to the control. This study showed potential inhibition to the growth of this food pathogen, suggesting the possibility to improve the hygienic food quality.<o:p></o:p></span></p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Exploratory%20test" title="Exploratory test">Exploratory test</a>, <a href="https://publications.waset.org/search?q=lactic%20acid%20bacteria" title=" lactic acid bacteria"> lactic acid bacteria</a>, <a href="https://publications.waset.org/search?q=crude%20bacteriocins" title=" crude bacteriocins"> crude bacteriocins</a>, <a href="https://publications.waset.org/search?q=spoilage" title=" spoilage"> spoilage</a>, <a href="https://publications.waset.org/search?q=pathogens." title=" pathogens."> pathogens.</a> </p> <a href="https://publications.waset.org/9997600/exploratory-tests-of-crude-bacteriocins-from-autochthonous-lactic-acid-bacteria-against-food-borne-pathogens-and-spoilage-bacteria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9997600/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9997600/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9997600/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9997600/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9997600/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9997600/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9997600/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9997600/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9997600/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9997600/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9997600.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2352</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">735</span> Effect of Chemical Additive on Fixed Abrasive Polishing of LBO Crystal with Non-water Based Slurry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jun%20Li">Jun Li</a>, <a href="https://publications.waset.org/search?q=Wenze%20Wang"> Wenze Wang</a>, <a href="https://publications.waset.org/search?q=Zhanggui%20Hu"> Zhanggui Hu</a>, <a href="https://publications.waset.org/search?q=Yongwei%20Zhu"> Yongwei Zhu</a>, <a href="https://publications.waset.org/search?q=Dunwen%20Zuo"> Dunwen Zuo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Non-water based fixed abrasive polishing was adopted to manufacture LBO crystal for nano precision surface quality because of its deliquescent.

The consistency of the values of the experimental tie-lines was determined through the Othmer-Tobias and Hands correlations. For the extraction effectiveness of solvents, the distribution and selectivity curves were plotted. In addition, these experimental tieline data were also correlated with NRTL model. The interaction parameters for the NRTL model were retrieved from the obtained experimental results by means of a combination of the homotopy method and the genetic algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Liquid-liquid%20equilibria" title="Liquid-liquid equilibria">Liquid-liquid equilibria</a>, <a href="https://publications.waset.org/search?q=homotopy%20methods" title=" homotopy methods"> homotopy methods</a>, <a href="https://publications.waset.org/search?q=carboxylic%20acid" title=" carboxylic acid"> carboxylic acid</a>, <a href="https://publications.waset.org/search?q=NRTL." title=" NRTL."> NRTL.</a> </p> <a href="https://publications.waset.org/4431/liquid-liquid-equilibria-for-ternary-mixtures-of-water-carboxylic-acid-mibk-experimental-simulation-and-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/4431/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/4431/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/4431/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/4431/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/4431/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/4431/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/4431/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/4431/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/4431/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/4431/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/4431.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">5623</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">732</span> Lactic Acid-Chitosan Films’ Properties and Their in vivo Wound Healing Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=T.%20S.%20Moe">T.

Khaing</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Chitosan is a derivative of chitin, a compound usually isolated from the shells of some crustaceans such as crab, lobster and shrimp. It has biocompatible, biodegradable, and antimicrobial properties. To use these properties of chitosan in biomedical fields, chitosan films (1%, 2%, 3% and 4%) were prepared by using l% lactic acid as solvent. The effects of chitosan films on tensile strength, elongation at break, degree of swelling, thickness, morphology, allergic and irritation reactions and antibacterial property were evaluated. Staphylococcus aureus and Escherichia coli were used as tested microorganisms. In vivo wound healing activities of chitosan films were investigated using mice model. As results, Chitosan films have similar appearance and good swelling properties and 4% chitosan film showed the better swelling activity and the greatest elongation ratio than the other chitosan films. They also showed their good activity of wound healing in mice model. Moreover, the results showed that the films did not produce any unwilling symptoms (allergy or irritation). In conclusion, it is evident that the chitosan film has the potentiality to use as wound healing biofilms in the biomedical fields.</p> <p class="card-text"><strong>Keywords:</strong> <a
