This study investigates the antimicrobial activity at different pH levels. Nylon 6,6 fabrics were treated with different chitosan solutions. Additionally, samples were treated also in basic conditions to see the antimicrobial activities. AATCC Test Method 100 was followed to evaluate the antimicrobial activity using Staphylococcus aureus ATCC 6538 test inoculum. The pH of the chitosan solutions was controlled below 6.5 since chitosan shows its antimicrobial activity only in acidic conditions because of its poor solubility above 6.5. In basic conditions, the samples did not show any antimicrobial activity. It appears from SEM images that the bonded chitosan in the structures exists. In acidic media (ph < 6.5), all samples showed antimicrobial activity. No correlation was found between pH levels and antimicrobial activity in acidic media. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chitosan" title="chitosan">chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=nylon%206" title=" nylon 6"> nylon 6</a>, <a href="https://publications.waset.org/abstracts/search?q=6" title="6">6</a>, <a href="https://publications.waset.org/abstracts/search?q=crosslinking" title=" crosslinking"> crosslinking</a>, <a href="https://publications.waset.org/abstracts/search?q=pH%20stability" title=" pH stability"> pH stability</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title=" antimicrobial"> antimicrobial</a> </p> <a href="https://publications.waset.org/abstracts/74096/the-effect-of-solution-ph-of-chitosan-on-antimicrobial-properties-of-nylon-66-fabrics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74096.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">219</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">831</span> Discerning of Antimicrobial Potential of Phenylpropanoic Acid Derived Oxadiazoles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neeraj%20Kumar%20Fuloria">Neeraj Kumar Fuloria</a>, <a href="https://publications.waset.org/abstracts/search?q=Shivkanya%20Fuloria"> Shivkanya Fuloria</a>, <a href="https://publications.waset.org/abstracts/search?q=Amit%20%20Singh"> Amit Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> 2-Phenyl propionic acid and oxadiazoles possess antimicrobial potential. 2-Phenyl propane hydrazide (1), on cyclization with aromatic acids offered 2-aryl-5-(1-phenylethyl)-1,3,4-oxadiazole derivatives (1A-E).

Organic acids, sulfur dioxide, sulfide, nitrate, nitrite, dimethyl dicarbonate and several preservative gases have been used as chemical preservatives in foods as well as natural preservatives which are indigenous in foods. It is determined that usage of herbal preservatives such as blueberry, dried grape, prune, garlic, mustard, spices inhibited several microorganisms. Moreover, it is determined that animal origin preservatives such as whey, honey, lysosomes of duck egg and chicken egg, chitosan have antimicrobial effect. Other than indigenous antimicrobials in foods, antimicrobial agents produced by microorganisms could be used as natural preservatives. The antimicrobial feature of preservatives depends on the antimicrobial spectrum, chemical and physical features of material, concentration, mode of action, components of food, process conditions, and pH and storage temperature. In this review, studies about antimicrobial components which are indigenous in food (such as herbal and animal origin antimicrobial agents), antimicrobial materials synthesized by microorganisms, and their usage as an antimicrobial agent to preserve foods are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=animal%20origin%20preservatives" title="animal origin preservatives">animal origin preservatives</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title=" antimicrobial"> antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20preservatives" title=" chemical preservatives"> chemical preservatives</a>, <a href="https://publications.waset.org/abstracts/search?q=herbal%20preservatives" title=" herbal preservatives"> herbal preservatives</a> </p> <a href="https://publications.waset.org/abstracts/61833/natural-preservatives-an-alternative-for-chemical-preservative-used-in-foods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61833.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">377</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">827</span> Characterization and Optimization of Antimicrobial Compound/S Produced by Asperigillus Fumigatus Isolated from Monuments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20A.%20M.%20Kewisha">Mohammad A. M. Kewisha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Xerophilic fungi , which are responsible for many cases of biodeterioration monuments, have been known as an interesting source of antimicrobial compounds. Sixty nine fungal strains, isolated from different localities and species inside Egyptian museums, were screened for antimicrobial activity against some bacterial species and unicellular fungi. The most potent antimicrobial activity was obtained by Asperigillus fumigatus which was identified by ITS4 ……. and showed activity against Staphylococcus aureus with 20 mm and C. albicans with18 mm of inhibition zone. Different parameters were optimized to enhance this activity. The culture grown under stationary conditions for 8 days at 30°C and pH 8 gave the best antimicrobial activity. Moreover, both starch and yeast extract showed the most suitable carbon and nitrogen sources, respectively. The antimicrobial compound was purified and subjected to spectroscopic characterization, which revealed that the antimicrobial compound might be 5,7 ethoxy, 4\,5\ methoxy isorhamnetin -3- O- galactoside. This study suggests that Aspergillus fumagates as a potential candidate offering a better scope for the production, purification and isolation of broad-spectrum antimicrobial compounds. These findings will facilitate the scale-up and further purification to ascertain the compounds responsible for antimicrobial activity, which can be exploited for the treatment of biodeterioration monuments and pharmaceutical applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title="antimicrobial activity">antimicrobial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=asperigillus%20fumigatus" title=" asperigillus fumigatus"> asperigillus fumigatus</a>, <a href="https://publications.waset.org/abstracts/search?q=Identification%20by%20ITS4" title=" Identification by ITS4"> Identification by ITS4</a>, <a href="https://publications.waset.org/abstracts/search?q=Staphylococcus%20aureus" title=" Staphylococcus aureus"> Staphylococcus aureus</a>, <a href="https://publications.waset.org/abstracts/search?q=C.albicans" title=" C.albicans"> C.albicans</a> </p> <a href="https://publications.waset.org/abstracts/171668/characterization-and-optimization-of-antimicrobial-compounds-produced-by-asperigillus-fumigatus-isolated-from-monuments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171668.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">54</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">826</span> Drug Use Knowledge and Antimicrobial Drug Use Behavior</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pimporn%20Thongmuang">Pimporn Thongmuang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The import value of antimicrobial drugs reached approximately fifteen million Baht in 2010, considered as the highest import value of all modern drugs, and this value is rising every year. Antimicrobials are considered the hazardous drugs by the Ministry of Public Health. This research was conducted in order to investigate the past knowledge of drug use and Antimicrobial drug use behavior. A total of 757 students were selected as the samples out of a population of 1,800 students. This selected students had the experience of Antimicrobial drugs use a year ago. A questionnaire was utilized in this research. The findings put on the view that knowledge gained by the students about proper use of antimicrobial drugs was not brought into practice. This suggests that the education procedure regarding drug use needs adjustment. And therefore the findings of this research are expected to be utilized as guidelines for educating people about the proper use of antimicrobial drugs. At a broader perspective, correct drug use behavior of the public may potentially reduce drug cost of the Ministry of Public Health of Thailand. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drug%20use%20knowledge" title="drug use knowledge">drug use knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20drugs" title=" antimicrobial drugs"> antimicrobial drugs</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20use%20behavior" title=" drug use behavior"> drug use behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=drug" title=" drug"> drug</a> </p> <a href="https://publications.waset.org/abstracts/3900/drug-use-knowledge-and-antimicrobial-drug-use-behavior" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3900.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">280</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">825</span> Antimicrobial Activity of the Cyanobacteria spp. against Fish Pathogens in Aquaculture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Tulay%20Cagatay">I.

Some of these organisms are nowadays used directly in the food, cosmetic and pharmaceutical industry, or in aquaculture and biotechnological approaches like biofuel or drug therapy. Finding the effective, environmental friendly chemotropic and antimicrobial agents to control fish pathogens are crucial in a country like Turkey which has a production capacity of about 240 thousand tons of cultured fish and has 2377 production farms and which is the second biggest producer in Europe. In our study, we tested the antimicrobial activity of cyanobacterium spp. against some fish pathogens Aeromonas hydrophila and Yersinia ruckeri that are important pathogens for rainbow trout farms. Agar disk diffusion test method was used for studying antimicrobial activity on pathogens. Both tested microorganisms have shown antimicrobial activity positively as the inhibition zones were 0.45 mm and 0.40 mm respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fish%20pathogen" title="fish pathogen">fish pathogen</a>, <a href="https://publications.waset.org/abstracts/search?q=cyanobacteria" title=" cyanobacteria"> cyanobacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title=" antimicrobial activity"> antimicrobial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=trout" title=" trout"> trout</a> </p> <a href="https://publications.waset.org/abstracts/83606/antimicrobial-activity-of-the-cyanobacteria-spp-against-fish-pathogens-in-aquaculture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83606.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">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">824</span> Phytochimical Screening and Antimicrobial Activity of Ethanolic Extract of Solenostemma Argel (Asclepiadaceae)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Acheuk">Fatma Acheuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Akila%20Hamichi"> Akila Hamichi</a>, <a href="https://publications.waset.org/abstracts/search?q=Siham%20Semmar"> Siham Semmar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The crude ethanolic extract from Solenostemma argel was obtained by maceration of leaves and stems of the plant.

Antimicrobial substances are natural or artificial agents that produced by microorganisms or obtained semi/total chemical synthesis are used at low concentrations to inhibit the growth of other microorganisms. Food borne pathogens and spoilage microorganisms are inactivated by the use of antagonistic microorganisms and their metabolites. Yeasts can produce toxic proteins or glycoproteins (toxins) that cause inhibition of sensitive bacteria and yeast species. Antimicrobial substance producing phenotypes belonging different yeast genus were isolated from different sources. Toxins secreted by many yeast strains inhibiting the growth of other yeast strains. These strains show antimicrobial activity, inhibiting the growth of mold and bacteria. The effect of antimicrobial agents produced by yeasts can be extremely fast, and therefore may be used in various treatment procedures. Rapid inhibition of microorganisms is possibly caused by microbial cell membrane lipopolysaccharide binding and in activation (neutralization) effect. Antimicrobial agents inhibit the target cells via different mechanisms of action. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20agents" title="antimicrobial agents">antimicrobial agents</a>, <a href="https://publications.waset.org/abstracts/search?q=yeast" title=" yeast"> yeast</a>, <a href="https://publications.waset.org/abstracts/search?q=toxic%20protein" title=" toxic protein"> toxic protein</a>, <a href="https://publications.waset.org/abstracts/search?q=glycoprotein" title=" glycoprotein"> glycoprotein</a> </p> <a href="https://publications.waset.org/abstracts/9513/antimicrobial-agents-produced-by-yeasts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9513.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">363</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">820</span> Prevalence and Antimicrobial Resistance of Salmonella spp. Isolated from Pigs at Slaughterhouses in Northeast of Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunpetch%20Angkititrakul">Sunpetch Angkititrakul</a>, <a href="https://publications.waset.org/abstracts/search?q=Seree%20Klaengair"> Seree Klaengair</a>, <a href="https://publications.waset.org/abstracts/search?q=Dusadee%20Phongaran"> Dusadee Phongaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Arunee%20Ritthipanun"> Arunee Ritthipanun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study is to determine the prevalence and antimicrobial resistance pattern of Salmonella spp. isolated from pigs at slaughterhouses in the northeast of Thailand.

In the present research, we report the synthesis and in-vitro antimicrobial activity of a new series of novel quinazolino-thiadiazoles 3 (a-j). The synthesized compounds were confirmed by melting point, IR, 1H-NMR, 13C NMR and Mass spectroscopy. In general, the results of the in-vitro antibacterial activity are encouraging, as out of 10 compounds tested, Compound 3f and 3i with a 4-chloro phenyl and 4-nitro phenyl at C-2 of thiadiazolyl of quinazolino-thiadiazoles, displayed the excellent antibacterial and antifungal activities against all the tested microorganisms (Bacterial and Fungal strain) with MIC values of 62.5 μg/mL. It is worth to mention that the combination of two biologically active moieties quinazoline and thiadiazole profoundly influences the biological activity. While evaluating the antimicrobial activity, it was observed that compounds having electron withdrawing groups on thiazole has shown profound activity in comparison to compounds having electron releasing groups. As a result of this study, it can be concluded that halogen substituent on thiazole ring increases antimicrobial activity. Possible improvements in the antimicrobial activity can be further achieved by slight modifications in the substituent’s and/or additional structural activity investigations to have good antimicrobial activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antifungal" title="antifungal">antifungal</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title=" antimicrobial"> antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=quinazolino-thiazoles" title=" quinazolino-thiazoles"> quinazolino-thiazoles</a>, <a href="https://publications.waset.org/abstracts/search?q=synthesis" title=" synthesis "> synthesis </a> </p> <a href="https://publications.waset.org/abstracts/20080/quinazolino-thiazoles-fused-pharmacophores-as-antimicrobial-agents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20080.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">416</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">818</span> Biological Activity of Essential Oils from Salvia nemorosa L.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdol-Hassan%20Doulah">Abdol-Hassan Doulah </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, antimicrobial activity of essential oil and ethyl acetate and ether extracts of S. nemorosa were examined against some species of bacteria and fungi. The essential oil of the aerial part of S. nemorosa was examined by GC and GC-MS. In the essential oil of S. nemorosa 26 Compounds have been identified. 2-Nonanone (44.09 %), 2-Undecanone (33.79 %), E-Caryophyllene (3.74 %) and 2-Decanone (2.89 %) were the main components of the essential oil. The essential oil analysis showed greatest antimicrobial activity against Staphylococcus epidermidis (5.3 μg/ml) and S. cerevisiae (9.3 μg/ml). The ethyl acetate showed greatest antimicrobial activity against Bacillus subtilis (106.7 μg/ml), Candida albicans (5.3 μg/ml) and ether extract showed greatest antimicrobial activity against Klebseilla pneumoniae (10.7 μg/ml) and Saccharomyces cerevisiae (10.7 μg/ml). In conclusion, we suggest that the antimicrobial activity of S. nemorosa may be due to its content of germacrene and linalool. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20activity" title="antibacterial activity">antibacterial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=antifungal%20activity" title=" antifungal activity"> antifungal activity</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvia%20nemorosa%20L." title=" Salvia nemorosa L."> Salvia nemorosa L.</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20oils" title=" essential oils"> essential oils</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20activity" title=" biological activity"> biological activity</a> </p> <a href="https://publications.waset.org/abstracts/31804/biological-activity-of-essential-oils-from-salvia-nemorosa-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31804.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">494</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">817</span> Nanocomposite Metal Material: Study of Antimicrobial and Catalytic Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roman%20J.%20Jedrzejczyk">Roman J.

As a result, dense, uniform zirconium dioxide films were obtained on the kanthal sheets which can be used as support materials in antimicrobial converters with sophisticated shapes. The material was characterised by physicochemical methods, such as AFM, SEM, EDX, XRF, XRD, XPS and in situ Raman and DRIFT spectroscopy. In terms of antimicrobial activity, the material was tested by ATP/AMP method using model microbes isolated from the real systems. The results show that the material can be potentially used in the market as a good candidate for active package and as active bulkheads of climatic systems. The mechanical tests showed that the developed method is an efficient way to obtain durable converters with high antimicrobial activity against fungi and bacteria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20properties" title="antimicrobial properties">antimicrobial properties</a>, <a href="https://publications.waset.org/abstracts/search?q=kanthal%20steel" title=" kanthal steel"> kanthal steel</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposite" title=" nanocomposite"> nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=zirconium%20oxide" title=" zirconium oxide"> zirconium oxide</a> </p> <a href="https://publications.waset.org/abstracts/83482/nanocomposite-metal-material-study-of-antimicrobial-and-catalytic-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83482.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">201</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">816</span> Antimicrobial Resistance Patterns of Salmonella spp. Isolate from Chickens at Slaughterhouses in Northeast of Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seree%20Klaengair">Seree Klaengair</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunpetch%20Angkititrakul"> Sunpetch Angkititrakul</a>, <a href="https://publications.waset.org/abstracts/search?q=Dusadee%20Phongaran"> Dusadee Phongaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaiyaporn%20Soikum"> Chaiyaporn Soikum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objectives of this study is to determine the prevalence and antimicrobial resistance pattern of Salmonella spp. isolated from chickens at slaughterhouses in northeast of Thailand.

Enzymatic oxidation of lipids leading to formation of oxylipin is one of those modifications. Hydroxy fatty acids, one of those oxylipins have gained important attentions because of their structural and functional properties compared with other non-hydroxy fatty acids. Recently 7,10-dihydroxy-8(E)-octadecenoic acid (DOD) was produced with high yield from lipid-containing oleic acid by microbial conversion, and the further study confirmed that DOD contained strong antimicrobial activities against a broad range of microorganisms. In this study, we tried to modify DOD molecules by the enzymatic or physical reaction to create new functionality or to enhance the antimicrobial activity of DOD. After modification of DOD molecules by different ways, we confirmed that the antimicrobial activity of DOD was highly enhanced and presented strong antimicrobial activities against multidrug-resistant Staphylococcus aureus, suggesting that DOD and its derivatives can be used as efficient antimicrobial agents for medical and industrial applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocatalysis" title="biocatalysis">biocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20agent" title=" antimicrobial agent"> antimicrobial agent</a>, <a href="https://publications.waset.org/abstracts/search?q=multidrug-resistant%20bacteria" title=" multidrug-resistant bacteria"> multidrug-resistant bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetable%20oil" title=" vegetable oil"> vegetable oil</a> </p> <a href="https://publications.waset.org/abstracts/75239/production-of-antimicrobial-agents-against-multidrug-resistant-staphylococcus-aureus-through-the-biocatalysis-of-vegetable-oils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75239.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">205</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">814</span> Recent Advancements and Future Trends in the Development of Antimicrobial Edible Films for Food Preservation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raana%20Babadi%20Fathipour">Raana Babadi Fathipour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Food packaging plays a crucial role in protecting food from unwanted external factors. Antibacterial edible films are a promising option for food packaging due to their biodegradability, environmental friendliness, and safety. This paper reviews recent research progress on antimicrobial edible films, focusing on those made from polysaccharides, proteins, and lipids. Polysaccharides and proteins are the primary components of antimicrobial edible films, while lipids primarily serve as plasticizers and carriers for active substances in composite films. For instance, second-generation liposomes have shown great potential as carriers for antimicrobial substances and other bioactive compounds due to their exceptional stability. Furthermore, this paper analyzes recent advancements and future trends in antimicrobial edible films. One promising direction is the integration of antimicrobial edible film materials with delivery systems, such as nanoemulsion and microencapsulation technologies, to ensure stable loading of bioactive substances. Another emerging area of interest is the development of smart and active packaging that allows consumers to assess the freshness of food products without opening the package. pH-sensitive films and smart fluorescent "on-off" sensors for humidity are currently being explored as materials for smart and active packaging to monitor food product freshness, with further exploration anticipated in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20edible%20film" title="antimicrobial edible film">antimicrobial edible film</a>, <a href="https://publications.waset.org/abstracts/search?q=biopolymer" title=" biopolymer"> biopolymer</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20agent" title=" antimicrobial agent"> antimicrobial agent</a>, <a href="https://publications.waset.org/abstracts/search?q=encapsulation" title=" encapsulation"> encapsulation</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20assay" title=" antimicrobial assay"> antimicrobial assay</a> </p> <a href="https://publications.waset.org/abstracts/176779/recent-advancements-and-future-trends-in-the-development-of-antimicrobial-edible-films-for-food-preservation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176779.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">59</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">813</span> Development of Antimicrobial Properties Nutraceuticals: Gummy Candies with Addition of Bovine Colostrum, Essential Oils and Probiotics </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Bartkiene">E.

For antimicrobial GC preparation, heteropolysaccharide (agar) was used. The antimicrobial properties of EOs (Eugenia caryophyllata, Thymus vulgaris, Citrus reticulata L., Citrus paradisi L.), BC, L. paracasei LUHS244, L. plantarum LUHS135, and their combinations against pathogenic bacteria strains (Streptococcus mutans, Enterococcus faecalis, Staphylococcus aureus, Salmonella enterica, Escherichia coli, Proteus mirabilis, and Pseudomonas aeruginosa) were evaluated. The highest antimicrobial properties by EO’s (Eugenia caryophyllata and Thymus vulgaris) were established. The optimal ingredients composition for antimicrobial GC preparation was established, which incorporate the BC fermented with L. paracasei LUHS244 in combination with Thymus vulgaris or Eugenia caryophyllata. These ingredients showed high inhibition properties of all tested pathogenic strains (except Pseudomonas aeruginosa). Antimicrobial GC formula consisting of thyme EO (up to 0.2%) and fermented BC (up to 3%), and for taste masking, mandarin or grapefruit EOs (up to 0.2%) was used. Developed GC high overall acceptability and antimicrobial properties, thus, antimicrobial GC could be a preferred form of nutraceuticals.

The chemical composition of the essential oil obtained by hydro-distillation was examined by GC/MS and the antimicrobial effect was studied on the growth of seven microbial species including Bacillus cereus, Pseudomonas aeruginosa and Proteus vulgaris using micro-dilution method. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined. Chemical composition analysis identified a total of 28 compounds in which the main components were menthol (32%), mentone (13.4), menthyl acetate (12%), 1,8-cineole (8.2%) and neomenthol (4%) representing 69.6 % of the total oil. Other separated components accounted for less than 30.4% of the oil. Results of antimicrobial analysis showed that the MIC values for Bacillus cereus, Pseudomonas aeruginosa and Proteus vulgaris was respectively 50, 200 and 100 µg/ml and the MBC was determined at 200, 400 and 200 µg/ml respectively.

The antioxidant activity of extract was evaluated in terms of radical scavenging potential (DPPH) and β-carotene bleaching assay. Total phenolic contents and flavonoid contents were also measured. Antimicrobial activity of these plants was tested against five microorganisms Pseu-domonas aeruginosa Bacillus subtilis, Escherichia coli, Staphylococcus aureus, and Candida albicans. The results showed that Pistacia lentiscus showed the highest antioxidant capacities using DPPH assay (IC50 = 4.60 μg/ml), while Populus trimula had the highest antioxidant activity in β-carotene/linolaic acid assay. The most interesting antimicrobial activity was obtained from Sysimbrium officinalis, Rhamnus alaternus, Origanum glandulosum, Cupressus sempervirens, Pinus halipensis and Centaurea calcitrapa.

Complete thermal, structural, mechanical and functional characterization were carried out of all formulations and determined the antimicrobial efficiency and returnable antimicrobial efficiency according to the Japanese Industrial Standard method. The morphology of the films showed agglomerates of particles in the composites. The active formulation had decreased elongation compared to the pure PP sample. Thermal analyses indicated that the active formulation compositions had increased thermal stability. The films showed 50% antimicrobial properties after the fifth wash against the tested microorganisms, presenting better activity against Gram negative organisms than Gram positive ones.

Research and technology are constantly involved to develop advanced finishing which can provide bacteriostatic growth without compromising the other typical properties of a textile as durability and non-toxicity, just to cite a few. Here we report on the antimicrobial coatings obtained, at room temperature and without the use of solvents, by means of the ion beam co-sputtering technique of an Ag target and a polytetrafluoroethylene one. In particular, such method allows to conjugate the well-known antimicrobial action of silver with the anti-stain and water-repellent properties of the fluoropolymer. Moreover, different Ag nanoparticle loadings (φ) were prepared by tuning the material deposition conditions achieving a fine control on film thickness and their antimicrobial/anti-stain properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title="antimicrobial">antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20beam%20sputtering" title=" ion beam sputtering"> ion beam sputtering</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocoatings" title=" nanocoatings"> nanocoatings</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-stain" title=" anti-stain"> anti-stain</a> </p> <a href="https://publications.waset.org/abstracts/6457/ion-beam-sputtering-deposition-of-inorganic-fluoropolymer-nano-coatings-for-real-life-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6457.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">392</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">807</span> Chemical Compositon and Antimicrobial Activity of Daucus aristidis Coss.

Ragazinskiene </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research focuses on phytochemistry and antimicrobial activities of compounds isolated and identified from three species of Eryngium. The antimicrobial activity of extracts from Eryngiumplanum L., Eryngium maritimum L., Eryngium campestre L. grown in Lithuania, were tested by the method of series dilutions, against different bacteria species: Escherichia coli, Proteus vulgaris and Staphylococcus aureus with and without antibiotic resistances, originating from livestock. The antimicrobial activity of extracts was described by determination of the minimal inhibitory concentration. Preliminary results show that the minimal inhibitory concentration range between 8.0 % and 17.0 % for the different Eryngium extracts and bacterial species.The total amounts ofphenolic compounds and total amounts of flavonoids were tested in the methanolic extracts of the plants. Identification and evaluation of the phenolic compounds were performed by liquid chromatography. The essential oils were analyzed by gas chromatography mass spectrometry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activities" title="antimicrobial activities">antimicrobial activities</a>, <a href="https://publications.waset.org/abstracts/search?q=Eryngium%20L.%20species" title=" Eryngium L. species"> Eryngium L. species</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20oils" title=" essential oils"> essential oils</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20chromatography%20mass%20spectrometry" title=" gas chromatography mass spectrometry"> gas chromatography mass spectrometry</a> </p> <a href="https://publications.waset.org/abstracts/4219/composition-and-in-vitro-antimicrobial-activity-of-three-eryngium-l-species" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4219.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">447</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">803</span> Comparison of Phenolic and Urushiol Contents of Different Parts of Rhus verniciflua and Their Antimicrobial Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jae%20Young%20Jang">Jae Young Jang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Hoon%20Ahn"> Jong Hoon Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Woong%20Lim"> Jae-Woong Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=So%20Young%20Kang"> So Young Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Mi%20Kyeong%20Lee"> Mi Kyeong Lee </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rhus verniciflua is commonly known as a lacquer tree in Korea. Stem barks of R. verniciflua have been used as an immunostimulator in traditional medicine. It contains phenolic compounds and is known for diverse biological activities such as antioxidant and antimicrobial activity. However, it also causes allergic dermatitis due to urushiols derivatives. For the development of active natural resources with less toxicity, the content of phenolic compounds and urushiols of different parts of R. verniciflua such as stem barks, lignum and leaves were quantitated by colorimetric assay and HPLC analysis. The urushiols content were the highest in stem barks, and followed by leaves. The lignum contained trace amount of urushiols. The phenolic contents, however, were the most abundant in lignum, and followed by leaves and stem barks. These results clear showed that the content of urushiols and phenolic differs depending on the parts of R. verniciflua. Antimicrobial activity of different parts of R. verniciflua against fish pathogenic bacteria was also investigated using Edwardsiella tarda. Lignum of R. verniciflua was the most effective in antimicrobial activity against E. tarda and phenolic constituents are suggested to be active constituents for activity. Taken together, phenolic compounds are responsible for antimicrobial activity of R. verniciflua. The lignum of R. verniciflua contains high content of phenolic compounds with less urushiols, which suggests efficient antimicrobial activity with less toxicity. Therefore, lignum of R. verniciflua are suggested as good sources for antimicrobial activity against fish bacterial diseases. <p class="card-text"><strong>Keywords:</strong> <a
