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. These findings suggest that PP films with AgSiO2, AgZn, and AgZ particles could provide a significant contribution to the quality and safety of seafood in the distribution chain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20film" title="antimicrobial film">antimicrobial film</a>, <a href="https://publications.waset.org/abstracts/search?q=properties%20and%20characterization" title=" properties and characterization"> properties and characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=returnable%20packaging" title=" returnable packaging"> returnable packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=sea%20food" title=" sea food"> sea food</a> </p> <a href="https://publications.waset.org/abstracts/57581/characterization-and-antimicrobial-properties-of-functional-polypropylene-films-incorporated-with-agsio2-agzn-and-agz-useful-as-returnable-packaging-in-seafood-distribution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57581.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">364</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">7372</span> The Effect of Solution pH of Chitosan on Antimicrobial Properties of Nylon 6,6 Fabrics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nil%C3%BCfer%20Y%C4%B1ld%C4%B1z%20Varan">Nilüfer Yıldız Varan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The antimicrobial activities of chitosan against various bacteria and fungi are well known, and the antimicrobial activity of chitosan depends on pH. 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">7371</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).

One significant advancement in this area is the inclusion of antimicrobial agents in bio-polymer-based edible films, which effectively inhibit or kill pathogenic/spoilage microbes that can contaminate food. This technology also helps reduce undesirable flavors caused by active compounds directly incorporated into the food. To further enhance the efficiency of antimicrobial bio-based packaging systems, Nano technological concepts such as bio-nano composites and Nano encapsulation systems have been applied.

Organisms causing biodeterioration on monuments have usually been controlled by chemical products (biocides). In order to overcome the impact of biocides on the environment, human health and monument substrates, alternative tools such as antimicrobial agents from natural products can be used for monuments conservation and protection. The problem is how to formulate antibacterial agents with high efficiency and low toxicity. Various types of biodegradable metal nanoparticles (MNPs) have many applications in plant extract delivery. So, Nano-encapsulation of metal and natural antimicrobial agents using polymers such as chitosan increases their efficacy, specificity and targeting ability. Green synthesis and characterization of metal nanoparticles such as silver with natural products extracted from some plants having antimicrobial properties, using the ecofriendly method one pot synthesis. Encapsulation of the new synthesized mixture using some biopolymers such as chitosan nanoparticles. The dispersions and homogeneity of the antimicrobial heterogeneous metal nanoparticles encapsulated by biopolymers will be characterized and confirmed by Fourier Transform Infrared Spectroscopy (FTIR), Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM) and Zeta seizer. The effect of the antimicrobial biopolymer metal nano-formulations on normal human cell lines will be investigated to evaluate the environmental safety of these formulations. The antimicrobial toxic activity of the biopolymeric antimicrobial metal nanoparticles formulations will be will be investigated to evaluate their efficiency towards different pathogenic bacteria and fungi. <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=biodeterioration" title=" biodeterioration"> biodeterioration</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20heritage" title=" cultural heritage"> cultural heritage</a>, <a href="https://publications.waset.org/abstracts/search?q=silver" title=" silver"> silver</a> </p> <a href="https://publications.waset.org/abstracts/167833/synthesis-and-characterization-of-heterogeneous-silver-nanoparticles-for-protection-of-ancient-egyptian-artifacts-from-microbial-deterioration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167833.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">81</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">7366</span> Natural Preservatives: An Alternative for Chemical Preservative Used in Foods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zerrin%20Erginkaya">Zerrin Erginkaya</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%B6zde%20Konuray"> Gözde Konuray</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microbial degradation of foods is defined as a decrease of food safety due to microorganism activity. 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">7365</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">7364</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.

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.

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">165</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">7362</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.

Bartelt-Hunt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Vegetative Filter Strips (VFS) are used for controlling the volume of runoff and decreasing contaminant concentrations in runoff before entering water bodies. Many studies have investigated the role of VFS in sediment and nutrient removal, but little is known about their efficiency for the removal of emerging contaminants such as antimicrobial resistance genes (ARGs). Vegetative Filter Strip Modeling System (VFSMOD) was used to simulate the efficiency of VFS in this regard. Several studies demonstrated the ability of VFSMOD to predict reductions in runoff volume and sediment concentration moving through the filters. The objectives of this study were to calibrate the VFSMOD with experimental data and assess the efficiency of the model in simulating the filter behavior in removing ARGs (ermB) and tylosin. The experimental data were obtained from a prior study conducted at the University of Nebraska (UNL) Rogers Memorial Farm. Three treatment factors were tested in the experiments, including manure amendment, narrow grass hedges and rainfall events. Sediment Delivery Ratio (SDR) was defined as the filter efficiency and the related experimental and model values were compared to each other. The VFS Model generally agreed with the experimental results and as a result, the model was used for predicting filter efficiencies when the runoff data are not available. Narrow Grass Hedges (NGH) were shown to be effective in reducing tylosin and ARGs concentration. The simulation showed that the filter efficiency in removing ARGs is different for different soil types and filter lengths. There is an optimum length for the filter strip that produces minimum runoff volume. Based on the model results increasing the length of the filter by 1-meter leads to higher efficiency but widening beyond that decreases the efficiency. The VFSMOD, which was proved to work well in estimation of VFS trapping efficiency, showed confirming results for ARG removal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20resistance%20genes" title="antimicrobial resistance genes">antimicrobial resistance genes</a>, <a href="https://publications.waset.org/abstracts/search?q=emerging%20contaminants" title=" emerging contaminants"> emerging contaminants</a>, <a href="https://publications.waset.org/abstracts/search?q=narrow%20grass%20hedges" title=" narrow grass hedges"> narrow grass hedges</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetative%20filter%20strips" title=" vegetative filter strips"> vegetative filter strips</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetative%20filter%20strip%20modeling%20system" title=" vegetative filter strip modeling system"> vegetative filter strip modeling system</a> </p> <a href="https://publications.waset.org/abstracts/129712/simulation-of-antimicrobial-resistance-gene-fate-in-narrow-grass-hedges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129712.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">132</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">7358</span> Antimicrobial Agents Produced by Yeasts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20B%C3%BCy%C3%BCks%C4%B1r%C4%B1t">T.

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">362</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">7357</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">415</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">7355</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.

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">492</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">7354</span> Antibacterial Hydrogels for Wound Care</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saba%20Atefyekta">Saba Atefyekta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: Control of bacterial bioburden in wounds is an important step for minimizing the risk of wound infection. An antimicrobial hydrogel wound dressing is developed out of soft polymeric hydrogels that contain antimicrobial peptides (AMPs). Such wound dressings can bind and kill all types of bacteria, even the resistance types at the wound site. Methods: AMPs are permanently bonded onto a soft nanostructured polymer via covalent attachment and physical entanglement. This improves stability, rapid antibacterial activity, and, most importantly, prevents the leaching of AMPs. Major Findings: Antimicrobial analysis of antimicrobial hydrogels using in-vitro wound models confirmed >99% killing efficiency against multiple bacterial trains, including MRSA, MDR, E. Coli. Furthermore, the hydrogel retained its antibacterial activity for up to 4 days when exposed to human serum. Tests confirmed no release of AMPs, and it was proven non-toxic to mammalian cells. An in-vivo study on human intact skin showed a significant reduction of bacteria for part of the subject’s skin treated with antibacterial hydrogels. A similar result was detected through a qualitative study in veterinary trials on different types of surgery wounds in cats, dogs, and horses. Conclusions: Antimicrobial hydrogels wound dressings developed by permanent attachment of AMPs can effectively and rapidly kill bacteria in contact. Such antibacterial hydrogel wound dressings are non-toxic and do not release any substances into the wound. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20wound%20dressing" title="antibacterial wound dressing">antibacterial wound dressing</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20peptides" title=" antimicrobial peptides"> antimicrobial peptides</a>, <a href="https://publications.waset.org/abstracts/search?q=post-surgical%20wounds" title=" post-surgical wounds"> post-surgical wounds</a>, <a href="https://publications.waset.org/abstracts/search?q=infection" title=" infection"> infection</a> </p> <a href="https://publications.waset.org/abstracts/162114/antibacterial-hydrogels-for-wound-care" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162114.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">80</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">7353</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">200</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">7352</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. During 2015-2016, all samples were isolated and identified by ISO 6579:2002. A total of 604 samples of rectal swab were collected and isolated for the presence of Salmonella. Salmonella was detected in 109 of 604 (18.05%) samples. The most prevalent serovars were Salmonella Kentucky (22.94%), Give (20.18%) and Typhimurium (7.34%). In this study, 66.97% of the isolates were resistant to at least one antimicrobial drug and 38.39% were multidrug resistant. The highest resistances were found in nalidixic acid (49.54%), ampicillin (30.28%), tetracycline (27.52%), amoxicillin (26.61%), ciprofloxacin (23.85) and norfloxacin (19.27%). The results showed high prevalence of Salmonella spp. in chickens and antimicrobial resistance patterns.

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">202</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">7350</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">58</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">7349</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 resultant Ag: HAp films coated on commercially pure Si disks substrates were systematically characterized by Scanning Electron Microscopy (SEM) coupled with X-ray Energy Dispersive Spectroscopy detector (X-EDS), Glow Discharge Optical Emission Spectroscopy (GDOES) and Fourier Transform Infrared spectroscopy (FT-IR). GDOES measurements show that a substantial Ag content has been deposited in the films. The X-EDS and GDOES spectra revealed the presence of a material composed mainly of phosphate, calcium, oxygen, hydrogen and silver. The antimicrobial efficiency of Ag:HAp thin films against Escherichia coli and Staphylococcus aureus bacteria was demonstrated. Ag:HAp thin films could lead to a decrease of infections especially in the case of bone and dental implants by surface modification of implantable medical devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=silver" title="silver">silver</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroxyapatite" title=" hydroxyapatite"> hydroxyapatite</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title=" thin films"> thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=GDOES" title=" GDOES"> GDOES</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a>, <a href="https://publications.waset.org/abstracts/search?q=FTIR" title=" FTIR"> FTIR</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20effect" title=" antimicrobial effect"> antimicrobial effect</a> </p> <a href="https://publications.waset.org/abstracts/2458/production-and-characterization-of-silver-doped-hydroxyapatite-thin-films-for-biomedical-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2458.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">425</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">7345</span> Retrospective Audit of Antibiotic Prophylaxis in Spinal Patient at Mater Private Network Cork 2019 vs 2021</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ciaran%20Smiddy">Ciaran Smiddy</a>, <a href="https://publications.waset.org/abstracts/search?q=Fergus%20Nugent"> Fergus Nugent</a>, <a href="https://publications.waset.org/abstracts/search?q=Karen%20Fitzmaurice"> Karen Fitzmaurice</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A measure of prescribing and administration of Antimicrobial Prophylaxis before and during Covid-19(2019 vs. 2021) was desired to assess how these were affected by Covid-19.

To reduce the inconveniences produced by these pesticides, the use of "biopesticides" originated from plants could be an alternative. The aim of this work is the valuation of a botanical species: Eucalyptus camaldulensis from Northeastern Algeria which extracts are supposed to have an antimicrobial activity, similar to pesticides. The extraction of secondary metabolites from the leaves of E. camaldulensis was realized using methanol and water, and measurements of total polyphenols were made by spectrometric method. Determination of the antimicrobial activity of the extracts at issue was realized in vitro on phyto-pathogenic fungal and bacterial stumps. Tests of comparison were included in the essays by using the chemical pesticidal products of synthesis. The obtained results show that the plant contains polyphenols with an efficiency mattering of the order of 22 %. These polyphenols have a strong fungicidal and bactericidal pesticidal activity against various microbial stumps and the values of the zones of inhibition are more important compared with that obtained in the presence of the chemicals of synthesis (fungicide). <p class="card-text"><strong>Keywords:</strong> <a
