The serious nature of these infections is compounded by increasing levels of drug resistance. Pure cultures of the Candida sp. were obtained from clinical isolates and fresh garlic extracts were obtained by extraction techniques. The antifungal activity of garlic extract was investigated in an in vitro system. The extract (100%, 75% and 50%) showed significant antifungal activity against Candida, whereas, low concentration (25%) of the extract showed less antifungal activity against the test organism. Antifungal activities of honey and lemon juice were tested against the Candida; however, the growth was not inhibited by these extracts. On the other hand honey and lemon when combined with garlic exhibited a good antifungal activity. The study thus confirms the antifungal properties of garlic extract along with additives like honey and lemon have significant antifungal activity against isolates of Candida species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Candida" title="Candida">Candida</a>, <a href="https://publications.waset.org/abstracts/search?q=garlic%20extract" title=" garlic extract"> garlic extract</a>, <a href="https://publications.waset.org/abstracts/search?q=lemon" title=" lemon"> lemon</a>, <a href="https://publications.waset.org/abstracts/search?q=synergitic%20antifungal%20activity" title=" synergitic antifungal activity"> synergitic antifungal activity</a> </p> <a href="https://publications.waset.org/abstracts/75056/an-in-vitro-study-on-synergetic-antifungal-activity-of-garlic-extract-with-honey-and-lemon-juice-against-candida-sp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75056.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">250</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">211</span> Synthesis of Antifungal by the Use of Green Catalyst</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elmeliani%20M%E2%80%99Hammed">Elmeliani M’Hammed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The work is carried out for the synthesis of antifungal effective against the fungus Fusarium oxysporum, Albedinis (Foa), the causative agent of bayoud, dates palm disease, through the use of raw clay as a green catalyst.

Material and Methods: A wild-type C. auris strain and its antifungal resistant derivative strain that is generated through induction by antifungal agents were used in this study. The strains were cultured onto media containing beauvericin alone or in combination with azole agents. Moreover, expression levels of four ABC-type transporter’s homologs in those strains were analyzed by real time PCR with or without antifungal stress by fluconazole or voriconazole. Results: Addition of beauvericin helped to partially restore the susceptibility of the resistant strain against fluconazole, suggesting participation of ABC-type transporters in the resistance mechanism. Real time PCR results showed that mRNA levels of three out of the four analyzed transporters in the resistant strain were more than 2-fold higher than their counterparts in the wild-type strain under negative control and antifungal agent-containing conditions. Conclusion: C. auris is an emerging multidrug-resistant pathogen causing human mortality worldwide. Providing effective treatment has been hampered by the resistance to antifungal drugs, demanding understanding the resistance mechanism in order to devise new therapeutic strategies. Our data suggest a partial contribution of ABC-type transporters to the resistance of this pathogen. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=resistance" title="resistance">resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=C.%20auris" title=" C. auris"> C. auris</a>, <a href="https://publications.waset.org/abstracts/search?q=transporters" title=" transporters"> transporters</a>, <a href="https://publications.waset.org/abstracts/search?q=antifungi" title=" antifungi"> antifungi</a> </p> <a href="https://publications.waset.org/abstracts/103949/role-of-abc-type-efflux-transporters-in-antifungal-resistance-of-candida-auris" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103949.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">169</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">209</span> Antifungal Activity of Silver Colloidal Nanoparticles against Phytopathogenic Fungus (Phomopsis sp.) in Soybean Seeds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20E.%20Mendes">J.

Therefore, the aim of this study was to evaluate the effect of silver nanoparticles (AgNPs) against Phomopsis sp. AgNPs were synthesized by silver nitrate reduction with sodium citrate and stabilized with ammonia. The synthesized AgNPs have further been characterized by UV/Visible spectroscopy, Biophysical techniques like Dynamic light scattering (DLS) and Scanning Electron Microscopy (SEM). The average diameter of the prepared silver colloidal nanoparticles was about 52 nm. Absolute inhibitions (100%) were observed on treated with a 270 and 540 µg ml-1 concentration of AgNPs. The results from the study of the AgNPs antifungal effect are significant and suggest that the synthesized silver nanoparticles may have an advantage compared with conventional fungicides. <p class="card-text"><strong>Keywords:</strong> <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=Phomopsis%20sp." title=" Phomopsis sp."> Phomopsis sp.</a>, <a href="https://publications.waset.org/abstracts/search?q=seeds" title=" seeds"> seeds</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanoparticles" title=" silver nanoparticles"> silver nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=soybean" title=" soybean"> soybean</a> </p> <a href="https://publications.waset.org/abstracts/13204/antifungal-activity-of-silver-colloidal-nanoparticles-against-phytopathogenic-fungus-phomopsis-sp-in-soybean-seeds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13204.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">459</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">208</span> Antifungal Lactobacilli Affect Mycelium Morphology and Protect Apricot Juice against Mold Spoilage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nora%20Laref">Nora Laref</a>, <a href="https://publications.waset.org/abstracts/search?q=Bettache%20Guessas"> Bettache Guessas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Preservation of foods mainly depends on delaying or inhibiting the growth of spoilage microorganisms, and antifungal activity of lactic acid bacteria is one of the technological properties researched.

The results of the antifungal activity performed radial growth on solid medium (PDA; potatoes dextrose agar) showed that the crude esters and their corresponding FAMEs have exhibited against the two strains tested. Overall, FAMEs have provided an antifungal effect more efficient than that of crude esters. Inhibition of Aspergillus ochraceus has been labeled with percentages ranging from 13.33 to 26.61% by crude esters, While FAMEs inhibition was ranged between 27.33 to 41.13%. However, the inhibition observed against the Aspergillus flavus was varying from 14.68 to 18.59% by crude esters compared with the inhibition percentages ranging from 21.5 to 33.45% by the FAMEs. The antifungal potency of esters oils seeds of the studied plants may be an alternative for consideration by the authorities interested, due to serving the public health, in reducing the fungal enormous peril. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Citrullus%20colocynthis%20L." title="Citrullus colocynthis L.">Citrullus colocynthis L.</a>, <a href="https://publications.waset.org/abstracts/search?q=Linum%20usitatissimum%20L." title=" Linum usitatissimum L."> Linum usitatissimum L.</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigella%20sativa%20L." title=" Nigella sativa L."> Nigella sativa L.</a>, <a href="https://publications.waset.org/abstracts/search?q=FAMEs" title=" FAMEs"> FAMEs</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=Aspergillus%20flavus" title=" Aspergillus flavus"> Aspergillus flavus</a>, <a href="https://publications.waset.org/abstracts/search?q=Aspergillus%20ochraceus" title=" Aspergillus ochraceus"> Aspergillus ochraceus</a> </p> <a href="https://publications.waset.org/abstracts/13961/antifungal-activity-of-free-fatty-acids-methyl-esters-extracted-from-citrullus-colocynthis-l-linum-usitatissimum-l-nigella-sativa-l-against-toxigenic-aspergillus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13961.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">269</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">206</span> Design, Synthesis and In-Vitro Antibacterial and Antifungal Activities of Some Novel Spiro[Azetidine-2, 3’-Indole]-2, 4(1’H)-Dione </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ravi%20J.%20Shah">Ravi J.

All the compounds were characterized using IR, 1H NMR, MS and elemental analysis. They were screened for their antibacterial and antifungal activities. Results revealed that, compounds (7a), (7b), (7c), (7d) and (7e) showed very good activity with MIC value of 6.25-12.5 μg/ml against three evaluated bacterial strains and the remaining compounds showed good to moderate activity comparable to standard drugs as antibacterial agents. Compounds (7c) and (7h) displayed equipotent antifungal activity in comparison to standard drugs. Structure-activity relationship study of the compounds showed that the presence of electron withdrawing group substitution at 5’ and 7’ positions of indoline ring and on ortho or para position of phenyl ring increases both antibacterial and antifungal activity of the compound. Henceforth, our findings will have a good impact on chemists and biochemists for further investigations in search of bromine containing spiro fused antimicrobial agents. <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=2-Azetidinone" title=" 2-Azetidinone"> 2-Azetidinone</a>, <a href="https://publications.waset.org/abstracts/search?q=indoline" title=" indoline "> indoline </a> </p> <a href="https://publications.waset.org/abstracts/26460/design-synthesis-and-in-vitro-antibacterial-and-antifungal-activities-of-some-novel-spiroazetidine-2-3-indole-2-41h-dione" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26460.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">491</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">205</span> An Antifungal Peptide from Actinobacteria (Streptomyces Sp.

The preservative action of LAB is due to several antimicrobial metabolites, including lactic acid, acetic acid, hydrogen peroxide, bacteriocins, carbon dioxide, diacetyl, and reuterin. Several studies have focused on the antifungal activity compounds from natural sources for biopreservation in alternatives to chemical use. LAB has an antifungal activity which may inhibit food spoilage fungi. Lactobacillus strains isolated from silage prepared in our laboratory by fermentation of grass in anaerobic condition were screened for antifungal activity with overlay assay against Aspergillus spp. The antifungal compounds were originated from organic acids; inhibitory activity did not change after treatment with proteolytic enzymes. Lactobacillus strains were able also to inhibit Trichoderma spp, Penicillium spp, Fusarium roseum, and Stemphylim spp by confrontation assay. The inhibitory activity could be detected against the mould Aspergillus spp in the apricot juice but not in a bakery product. These antifungal compounds have the potential to be used as food biopreservation to inhibit conidia germination, and mycelia growth of spoilage fungi depending on food type, pH of food especially in heat, and cold processed foods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lactic%20acid%20bacteria" title="lactic acid bacteria">lactic acid bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=Lactobacillus" title=" Lactobacillus"> Lactobacillus</a>, <a href="https://publications.waset.org/abstracts/search?q=Aspergillus" title=" Aspergillus"> Aspergillus</a>, <a href="https://publications.waset.org/abstracts/search?q=antifungal%20activity" title=" antifungal activity"> antifungal activity</a> </p> <a href="https://publications.waset.org/abstracts/12158/control-of-spoilage-fungi-by-lactobacilli" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12158.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">331</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">203</span> In vitro Antifungal Activity of Methanolic Extracts of Eight Various Cultivar of Persian Punica granatum L. against Candida Species</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahindokht%20Bassiri-Jahromi">Shahindokht Bassiri-Jahromi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Pourshafie"> Mohammad Reza Pourshafie</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzad%20Katiraee"> Farzad Katiraee</a>, <a href="https://publications.waset.org/abstracts/search?q=Mannan%20Hajimahmoodi"> Mannan Hajimahmoodi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Mostafavi">Ehsan Mostafavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Malihe%20Talebi"> Malihe Talebi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Resistance of Candida species to antifungal agents has potentially serious implications for management of infections. Candida species are now fourth common organisms isolated from hospitalized patients. It is important to increase effective therapy. In the past decade, numerous reports of treatment failures were reported. Prevention and control of these infections will require new antimicrobial agents. Plant-derived antifungal have always been a source of novel therapeutics. The aim of this study was to investigate the antifungal effect of methanolic extract of pomegranate peel and pulp against Candida species. Material and Methods: Eight cultivars of Punica granatum L. were collected from Saveh Agricultural Investigation Center in Iran. Both pomegranate pulp and peel were dried and powdered separately. The dried powders were extracted by using a soxhlet extractor. The antifungal effect of methanolic extract of pomegranate peel and pulp were determined in vitro by minimum inhibitory concentration (MIC) against five standard species of (ATCC 10231), C. parapsilosis (ATCC 22019), C. tropicalis (ATCC 750), C. glabrata (PTCC 5297), and C. kroseii (PTCC 5295). Results: Maximum inhibitions of antifungal effect were attributed to peel extract pomegranate cultivar and Candida species. The most potential antifungal inhibition among 8 different cultivars observed by sour malas, sour white peel, and sour summer extracts respectively, against five Candida strains. The antifungal activity of pulp extracts against Candida species was approximately negative. Conclusion: The use of Punica granatum peel extract has been shown to possess antifungal activities. The phytochemistry and pharmacological actions of Punica granatum peel components suggest a wide range of clinical applications for the treatment and prevention of candidiasis. <p class="card-text"><strong>Keywords:</strong> <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=Candida%20species" title=" Candida species"> Candida species</a>, <a href="https://publications.waset.org/abstracts/search?q=Punica%20granatum%20L." title=" Punica granatum L."> Punica granatum L.</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmacognosy" title=" pharmacognosy"> pharmacognosy</a> </p> <a href="https://publications.waset.org/abstracts/26336/in-vitro-antifungal-activity-of-methanolic-extracts-of-eight-various-cultivar-of-persian-punica-granatum-l-against-candida-species" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26336.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">483</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">202</span> Seasonal Stirred Variations in Chemical Composition and Antifungal Activity of Medicinal Plants Turraea holstii and Clausena anisata</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francis%20Machumi">Francis Machumi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ester%20Innocent"> Ester Innocent</a>, <a href="https://publications.waset.org/abstracts/search?q=Pius%20Yanda"> Pius Yanda</a>, <a href="https://publications.waset.org/abstracts/search?q=Philip%20C.%20Stevenson"> Philip C.

In the present research, thirty basidiomycetes isolated from various ecological niches of Georgia and belonging to different taxonomic groups were screened for their antifungal activities against pathogenic fungi such as Aspergillus, Fusarium, and Guignardia bidwellii. Among mushroom tested, several potential producers of antifungal substances have been revealed, such as Schizophyllum commune, Lentinula edodes, Ganoderma abietinum, Fomes fomentarius, Hericium erinaceus, and Trametes versicolor. For mushroom cultivation and expression of antifungal potential, submerged and solid-state fermentations of different plant raw materials were performed and various approaches and strategies have been exploited. Sch. commune appeared as a most promising producer of antifungal compounds. It was established that among different agro-industrial wastes, the presence of mandarin juice production waste in a nutrient medium, causing the significant increase of antifungal activity Sch. commune (growth inhibition: Aspergillus – 59 %, Fusarium – 55 %, G. bidwellii – 78 %, after 3, 2 and 4 days of cultivation, respectively). Besides this, Sch. commune demonstrate similar antifungal activities in the presence of glucose, glycerol, maltose, mannitol, and xylose, and growth inhibition of Fusarium ranged in 41 % - 49 % during 6 days of cultivation. Inhibition of Aspergillus growth inhibition varied in 27 % - 36 %, and inhibition of G. bidwellii was in the range 49 % - 61 %, respectively. Sch. commune under solid-state fermentation of mandarin peels at 13 days of cultivation demonstrates powerful growth inhibition of pathogenic fungi (growth inhibition: Aspergillus – 50 %, Fusarium – 61 %, G. bidwellii – 68 %, after 3, 4, and 4 days of cultivation, respectively) as well as at 20 days old mushroom (growth inhibition: Aspergillus – 41 %, Fusarium – 54 %, G. bidwellii – 66 %, after 3 days of cultivation). It was established that Sch. commune was effective as a producer of antifungal compounds in submerged as well as in solid-state fermentation. Finally, performed study confirms that the higher basidiomycetes possess antifungal potential, which strongly depends on the physiological factors of growth.

Over the past two decades, the incidence of fungal infections has increased due to the development of resistance. In this study, the QSAR was performed on a series of esters of 2-carboxamido-3-(1H-imidazole-1-yl) propanoic acid derivatives. These compounds have showed moderate and very good antifungal activity. The multiple linear regression (MLR) was used to generate the linear 2d-QSAR models. The dataset consists of 115 compounds with their antifungal activity (log MIC) against «Candida albicans» (ATCC SC5314). Descriptors were calculated, and different models were generated using Chemoffice, Avogadro, GaussView software. The selected model was validated. The study suggests that the increase in lipophilicity and the reduction in the electronic character of the substituent in R1, as well as the reduction in the steric hindrance of the substituent in R2 and its aromatic character, supporting the potentiation of the antifungal effect. The results of QSAR could help scientists to propose new compounds with higher antifungal activities intended for immunocompromised patients susceptible to multi-resistant nosocomial infections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quantitative%20structure%E2%80%93activity%20relationship" title="quantitative structure–activity relationship">quantitative structure–activity relationship</a>, <a href="https://publications.waset.org/abstracts/search?q=imidazole" title=" imidazole"> imidazole</a>, <a href="https://publications.waset.org/abstracts/search?q=antifungal" title=" antifungal"> antifungal</a>, <a href="https://publications.waset.org/abstracts/search?q=candida%20albicans%20%28ATCC%20SC5314%29" title=" candida albicans (ATCC SC5314)"> candida albicans (ATCC SC5314)</a> </p> <a href="https://publications.waset.org/abstracts/174183/construction-of-qsar-models-to-predict-potency-on-a-series-of-substituted-imidazole-derivatives-as-anti-fungal-agents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174183.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">84</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">199</span> Promissing Antifungal Chitinase from Marine Strain of Bacillus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ben%20Amar%20Cheba">Ben Amar Cheba</a>, <a href="https://publications.waset.org/abstracts/search?q=Taha%20Ibrahim%20Zaghloul"> Taha Ibrahim Zaghloul</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Hisham%20El-Massry"> Mohamad Hisham El-Massry</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Rafik%20El-Mahdy"> Ahmad Rafik El-Mahdy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Seventy two bacterial strains with ability to degrade chitin were isolated during a screening program.

R2 with a given accession number DQ 923161. This strain was able to produce high levels of extracellular chitinase. The chitinase of Bacillus sp. R2 hydrolyzed several chitinous substrates preferentially and showed a maximum activity toward the β chitin such as Calmar pen and squid bone chitins with the folds 1.47 and 1.23 respectively. The enzyme also exhibited a substrate binding capacity of more than 70% for squid chitin, shrimp shell colloidal chitin, chitosan and prawn shell chitin. The chitinase showed a moderate antifungal activity against many phytopathogenic fungi such as Aspergillus niger, A. flavus, Penicillium degitatum and Fusarium calmorum.This strain could be a suitable candidate for chitinase production on an industrial scale for using as promising antifungal biopestecide. <p class="card-text"><strong>Keywords:</strong> <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=Bacillus%20sp.%20R2" title=" Bacillus sp.

The rising of antifungal resistance severely lowers the efficacy of the limited antifungal agents available. New antifungal drugs that target new mechanisms are necessary to tackle the current shortfalls. Amongst post- modifications, phosphorylation is a predominant and an outstanding protein alteration in all eukaryotes. In fungi, protein phosphorylation plays a vital role in many signal transduction pathways, including cell cycle, cell growth, metabolism, transcription, differentiation, proliferation, and virulence. The investigation of Aspergillus fumigatus phosphatases revealed seven genes essential for viability. Inhibiting one of these phosphatases is a new interesting route to develop novel antifungal drugs. In this study, we carried out an early drug discovery process targeting oneessential phosphatase, GlcA. Here, we report the identification of new GlcA inhibitors that show antifungal activity. These important finding open a new avenue to the development of novel antifungals to expand the current narrow arsenal of clinical candidates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=invasive%20fungal%20diseases" title="invasive fungal diseases">invasive fungal diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphatases" title=" phosphatases"> phosphatases</a>, <a href="https://publications.waset.org/abstracts/search?q=GlcA" title=" GlcA"> GlcA</a>, <a href="https://publications.waset.org/abstracts/search?q=competitive%20inhibitors" title=" competitive inhibitors"> competitive inhibitors</a> </p> <a href="https://publications.waset.org/abstracts/154247/the-discovery-of-competitive-glca-inhibitors-that-inhibits-the-human-pathogenic-fungi-aspergillus-fumigatus-and-candida-albicans" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154247.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">120</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">196</span> Antifungal Susceptibility of Yeasts Isolated from Clinical Samples from a Tertiary Hospital from State of Puebla</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Munguia-Perez">Ricardo Munguia-Perez</a>, <a href="https://publications.waset.org/abstracts/search?q=Nayeli%20Remigio-Alvarado"> Nayeli Remigio-Alvarado</a>, <a href="https://publications.waset.org/abstracts/search?q=M.Miriam%20Hernandez-Arroyo"> M.Miriam Hernandez-Arroyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Elsa%20Casta%C3%B1eda-Roldan"> Elsa Castañeda-Roldan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fungi have emerged as important pathogens causing morbidity and mortality mainly in immunosuppressed, malnourished and elderly patients. It has detected an increase in resistance to azoles primarily to fluconazol. The fungal infections have become a problem of public health for the resistance to antifungal agents, they have developed new antifungals with broad-spectrum. The aim of this study was determine the antifungal susceptibility of yeasts isolated from clinical samples (respiratory secretions, exudates, wounds, blood cultures, urine cultures) obtained from inpatients and outpatients of a tertiary hospital from State of Puebla. The antifungal susceptibility of the yeast from several clinical samples were determined by the CLS M44-A disk diffusion methods. 149 samples of yeast were analyzed. All species were 100% susceptible to nystatin and amphotericin B. Candida albicans showed resistance of 95.5 % to fluconazole, 50.7 % to 5-flurocytosine and 55.2 % intermediate susceptibility to ketoconazole. Candida glabrata 81.3 % was susceptibility to ketoconazole and 75 % to fluconazole, for the case of 5-flurocytosine the 56.3 % was susceptible.

All concentrations of extracts from three hard corals showed no antifungal activity towards the tested strains. In antibacterial assays, the hard coral extracts showed significant activity solely against Staphylococcus aureus with MICs ranging from 3 to 9 μg/ml. The highest antibacterial activity was found in the aqueous methanol extract of Porites compressa with an inhibition zone of 22 mm against Staphylococcus aureus at 18 μg/ml extract concentration. Methanol extracts from Porites harrisoi and Porites compressa exhibited only weak cytotoxic activities. It is important for future research to concentrate on finding the mechanisms employed by corals to defend themselves against invasion, the mechanism of infections and the type of chemical compounds in coral extracts that inhibit antibacterial growth or proliferation in underexplored areas such as the Persian Gulf. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibacterial" title="antibacterial">antibacterial</a>, <a href="https://publications.waset.org/abstracts/search?q=antifungal" title=" antifungal"> antifungal</a>, <a href="https://publications.waset.org/abstracts/search?q=cytotoxic" title=" cytotoxic"> cytotoxic</a>, <a href="https://publications.waset.org/abstracts/search?q=hard%20corals" title=" hard corals"> hard corals</a>, <a href="https://publications.waset.org/abstracts/search?q=Persian%20Gulf" title=" Persian Gulf"> Persian Gulf</a> </p> <a href="https://publications.waset.org/abstracts/34016/screening-for-antibacterial-antifungal-and-cytotoxic-agents-in-three-hard-coral-species-from-persian-gulf" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34016.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">489</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">193</span> Beta-Cyclodextrin Inclusion Complexes for Antifungal Food Packaging Applications </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Munoz-Shuguli">Cristina Munoz-Shuguli</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Rodriguez"> Francisco Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20Bruna"> Julio Bruna</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Jose%20Galotto"> M.

The development of active food packaging materials with antifungal properties has been proposed as an innovative strategy in order to prevent this problem. In this way, natural compounds as the essential oils or their derivatives, also called volatile compounds (VC), can be incorporated in the food packaging materials to control the fungal growth during fruit packaging. However, if the VC is incorporated directly in the packaging material, it is released very fast due to VC high volatility. For this reason, the formation of inclusion complexes through the encapsulation of VC into beta-cyclodextrin (β-CD) and their incorporation in package materials is an alternative to maintain an antifungal atmosphere around the packaged fruits for longer times. In this context, the aim of this work was to develop inclusion complexes based in β-CD and VC (β-CD:VC) for further application in the antifungal food packaging materials development. β-CD:VC inclusion complexes were obtained with two different molar ratios 2:1 and 1:1, through co-precipitation method. The entrapment efficiency of β-CD:VC as well the release of antifungal compound from inclusion complexes exposed to different relative humidity (25, 50, and 97 %) to headspace were determined by gaseous chromatography (GC). Also, thermal and antimicrobial properties of β-CD:VC were determined through thermogravimetric analysis (TGA) and antifungal assays against Botrytis cinerea, respectively. GC results showed that β-CD:VC 2:1 had a higher entrapment efficiency than β-CD:VC 1:1, with values of 75.5 ± 3.71 % and 59.6 ± 1.51 %, respectively. It was probably because during the synthesis of β-CD:VC 1:1, there was less molecular space to the movement of VC molecules. Furthermore, the release of VC from β-CD:VC was directly related with the relative humidity. High amount of VC was released when the inclusion complexes were exposed to high humidity, possibly due to the interactions between the water molecules and the β-CD hydrophilic wall. On the other hand, a better thermal stability of VC in inclusion complexes allowed to verify its effective encapsulation into β-CD. Finally, antimicrobial assays showed that the inclusion complexes had a high antifungal activity at very low concentrations. Therefore, the results obtained in this work allow suggesting the β-CD:VC inclusion complexes as potential candidates to the development of fruit antifungal packaging materials, which activity is relative humidity dependent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Botrytis%20cinerea" title="Botrytis cinerea">Botrytis cinerea</a>, <a href="https://publications.waset.org/abstracts/search?q=fruit%20packaging" title=" fruit packaging"> fruit packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=headspace%20release" title=" headspace release"> headspace release</a>, <a href="https://publications.waset.org/abstracts/search?q=volatile%20compounds" title=" volatile compounds"> volatile compounds</a> </p> <a href="https://publications.waset.org/abstracts/125111/beta-cyclodextrin-inclusion-complexes-for-antifungal-food-packaging-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125111.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">122</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">192</span> Antifungal Activity of Commiphora myrrha L. against Some Air Fungi</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20E.%20Al-Sabri">Ahmed E.

The increasing population leads to an increase in demand for food. A large number of crops are infected by different microbes, and nutrient deficiency of soil adversely affects the yield of crops. Furthermore, the use of chemical fertilizers like Nitrogen, Phosphorus, Potassium (NPK) Urea, and Diammonium phosphate (DAP) and pesticides have environmental consequences. Therefore, there is an urgent need to explore alternative renewable and sustainable biofertilizers. Maize is one of the top growing crops in Pakistan, but it has low yield compared to other countries due to deficiency of organic matter, widespread nutrients deficiency (phosphorus and nitrogen), unbalanced use of fertilizers and various fungal diseases. In order to get rid of all these disadvantages, Digestate emerged as a win-win opportunity for the control of a few plant diseases and a replacement for the chemical fertilizers. The present study was designed to investigate the effect of Anerobic digestate on Antifungal Activity and in different parameters of Maize. The antifungal activity, minimum inhibitory concentration (MIC), and minimum fungicidal concentration (MFC) against selected phytopathogens (Colletotrichum coccodis, Pythium ultimum, Phytophthora capsci, Rhizoctonia solani, Bipolaris oryzae and Fusarium Fujikuroi) were determined by microtiter plate method. The effect of various fertilizers in different growth parameters height, diameter, chlorophyll, leaf area, biomass, and yield were studied in field experiments. The extracts from anaerobic digestate have shown antifungal activity against selected phytopathogens, the highest activity was noted against P. ultimum, the MIC activity was high in case of P. ultimum and B. oryzae. The present study concludes that anaerobic digestate have a positive effect on maize growth and yield as well as an antifungal activity which can be potentially a good biofertilizer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestate" title="anaerobic digestate">anaerobic digestate</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=MIC" title=" MIC"> MIC</a>, <a href="https://publications.waset.org/abstracts/search?q=phytopathogens" title=" phytopathogens"> phytopathogens</a> </p> <a href="https://publications.waset.org/abstracts/105304/investigation-of-the-effect-of-anaerobic-digestate-on-antifungal-activity-and-in-different-parameters-of-maize" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105304.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">125</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">190</span> In Vitro Antifungal Activity of Essential Oil Artemisia Absinthium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bouchenak%20Fatima">Bouchenak Fatima</a>, <a href="https://publications.waset.org/abstracts/search?q=Lmegharbi%20Abdelbaki"> Lmegharbi Abdelbaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Houssem%20Degaichia"> Houssem Degaichia</a>, <a href="https://publications.waset.org/abstracts/search?q=Benrebiha%20Fatima"> Benrebiha Fatima</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The essential oil composition of the leaf of Artemisia absinthium from region of Cherchell (The south of Algeria) was investigated by GC, GC-MS. 27 constituents were identified correspond to 84, 63% of the total oil.

Toxic metabolites produced by phytopathogenic fungi also pose significant risks to animal and human health. Extensive application of synthetic fungicides is not a sustainable solution since it poses risks to human, animal and environmental health. Unsaturated fatty acids may provide an environmentally friendly alternative because of their direct antifungal activity against phytopathogens as well as through the stimulation of plant defense pathways. The present study assessed the in vitro and in vivo efficacy of two hydroxy fatty acids, coriolic acid and ricinoleic acid, against the phytopathogens Fusarium graminearum, Pyrenophora tritici-repentis, Pyrenophora teres f. teres, Sclerotinia sclerotiorum, and Leptosphaeria maculans. Antifungal activity of coriolic acid and ricinoleic acid was evaluated using broth micro-dilution method to determine the minimum inhibitory concentration (MIC). Results indicated that both ricinoleic acid and coriolic acid showed antifungal activity against phytopathogens, with the strongest inhibitory activity against L. maculans, but the MIC varied greatly between species. An antifungal effect was observed for coriolic acid in vivo against pathogenic fungi of wheat and barley. This effect was not correlated to the in vitro activity because ricinoleic acid with equivalent in vitro antifungal activity showed no protective effect in vivo. Moreover, neither coriolic acid nor ricinoleic acid controlled fungal pathogens of canola. In conclusion, coriolic acid inhibits some phytopathogens in vivo and may have the potential to be an effective crop protection agent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coriolic%20acid" title="coriolic acid">coriolic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20inhibitory%20concentration" title=" minimum inhibitory concentration"> minimum inhibitory concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=pathogenic%20fungi" title=" pathogenic fungi"> pathogenic fungi</a>, <a href="https://publications.waset.org/abstracts/search?q=ricinoleic%20acid" title=" ricinoleic acid"> ricinoleic acid</a> </p> <a href="https://publications.waset.org/abstracts/92179/investigating-the-potential-use-of-unsaturated-fatty-acids-as-antifungal-crop-protective-agents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92179.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">177</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">186</span> Antifungal Potential of the Plant Growth-Promoting Rhizobacteria Infecting Kidney Beans</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhazira%20Shemsheyeva">Zhazira Shemsheyeva</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhanara%20Suleimenova"> Zhanara Suleimenova</a>, <a href="https://publications.waset.org/abstracts/search?q=Olga%20Shemshura"> Olga Shemshura</a>, <a href="https://publications.waset.org/abstracts/search?q=Gulnaz%20Mombekova"> Gulnaz Mombekova</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhanar%20Rakhmetova"> Zhanar Rakhmetova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bacteria that colonize plant roots and promote plant growth are referred to as plant growth-promoting rhizobacteria (PGPR). They not only provide nutrients to the plants (direct plant growth promotion) and protect plants against the phytopathogens (indirect plant growth promotion) but also increase the soil fertility. Indirectly PGPRs improve the plant growth by becoming a biocontrol agent for a fungal pathogen. The antifungal activities of the PGPrhizobacteria were assayed against different species of phytopathogenic fungi such as Fusarium tricinctum, Fusarium oxysporum, Sclerotiniasclerotiorum, and Botrytis cinerea. Pseudomonas putidaSM-1, Azotobacter sp., and Bacillus thuringiensis AKS/16 strains have been used in experimental tests on growth inhibition of phytopathogenic fungi infecting Kidney beans. Agar well diffusion method was used in this study. Diameters of the zones of inhibition were measured in millimeters. It was found that Bacillus thuringiensis AKS/16 strain showed the lowest antifungal activity against all fungal pathogens tested. Zones of inhibition were 15-18 mm. In contrast, Pseudomonas putida SM-1 exhibited good antifungal activity against Fusarium oxysporum and Fusarium tricinctum by producing 29-30 mm clear zones of inhibition. The moderate inhibitory effect was shown by Azotobacter sp. against all fungal pathogens tested with zones of inhibition from24 to 26 mm. In summary, Pseudomonas putida SM-1 strain demonstrated the potential of controlling root rot diseases in kidney beans. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PGPR" title="PGPR">PGPR</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudomonas%20putida" title=" pseudomonas putida"> pseudomonas putida</a>, <a href="https://publications.waset.org/abstracts/search?q=kindey%20beans" title=" kindey beans"> kindey beans</a>, <a href="https://publications.waset.org/abstracts/search?q=antifungal%20activity" title=" antifungal activity "> antifungal activity </a> </p> <a href="https://publications.waset.org/abstracts/120943/antifungal-potential-of-the-plant-growth-promoting-rhizobacteria-infecting-kidney-beans" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120943.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">154</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">185</span> Antimicrobial Activity of Igusa and the Application to Foam Materials for Food Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Nanako">I.

Igusa ( Juncus effuses var. decipiens ), which is commonly known in the forms of TATAMI. Juncus spp. grow at a relatively high humidity area (Japan, China and Southeast Asia ). Yatsushiro region in the southern part of Kumamoto prefecture is major produing area of Igusa. Igusa found to have honeycomb structure and was also shown to have the ability to control humidity. And Igusa has been used as a medicinal herb for diuretic and antiphlogistic agent. In previous study, we investigated antimicrobial effects of Igusa, and showed high antimicrobial activity against food poisoning bacteria. Therefore, the food trays blended Igusa can be kept clean by antimicrobial activity of Igusa. We focus on ‘Igusa foam materials’. In this study, we investigated the antibacterial and antifungal activity of Igusa, and new application to foam materials for food industry. Materials and method: We used Igusa foam materials (3 × 3 × 3 cm) as a sample. We set about fifteen types of samples combined with a commercial antibacterial agent A, a commercial antibacterial agent B, potassium laurate (C12K) and a commercial antifungal agent C, a commercial antifungal agent D and a commercial antifungal agent E. We selected four bacteria strains (Escherichia coli NBRC 3972, Staphylococus aureus NBRC 12732, Salmonella typhimurium NBRC 13245, Bacillus subtilis NBRC 3335 ) and three fungus strains (Penicillium pinophilum NBRC 6345, Cladosporium cladosporioides NBRC 30314, Aspergillus oryzae NBRC 5238 ). The fungus was cultured at 30 °C on Igusa foam materials after inoculation of the fungus for fourteen days. The bacteria was cultured at 30 °C on Igusa foam materials after inoculation of the bacteria for three days. And the Igusa foam materials were washed with 10 mL normal saline after three days. The normal saline washed Igusa foam materials plated the NA medium. After, It was cultured at 30 °C and used colony counting method. Result and Conclusion: The fifteen types of sample of Igusa foam materials had antifungal activity against C. cladosporioides, A. oryzae and P. pinophilum for fourteen days. The four types of sample contained potassium laurate and antibacterial agent A, sample contained antibacterial agent B and antifungal agent D, sample contained A and antifungal agent E, sample contained B and E had antibacterial activity against B. subtilis. The three types of sample contained potassium laurate and A, sample contained B and D, sample contained A and E had antibacterial activity against S. typhimurium. The five types of sample contained potassium laurate and A, sample contained B and D, sample contained A and E, sample contained B and E, sample contained B and antifungal agent C had antibacterial activity against E. coli and S. aureus. These results indicate that Igusa of Igusa foam materials had high antifungal activity. In addition, Igusa foam materials combined with a commercial antibacterial agent had antibacterial activity. In the future, we consider that use of Igusa foam materials may be spread from food industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibacterial" title="antibacterial">antibacterial</a>, <a href="https://publications.waset.org/abstracts/search?q=antifungal" title=" antifungal"> antifungal</a>, <a href="https://publications.waset.org/abstracts/search?q=foam%20materials" title=" foam materials"> foam materials</a>, <a href="https://publications.waset.org/abstracts/search?q=Igusa" title=" Igusa"> Igusa</a> </p> <a href="https://publications.waset.org/abstracts/49379/antimicrobial-activity-of-igusa-and-the-application-to-foam-materials-for-food-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49379.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">245</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">184</span> A Comparative Study on the Synthesis, Characterizations and Biological (Antibacterial and Antifungal) Activities of Zinc Doped Silica Oxide Nanoparticles Based on Various Solvents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Arshad">Muhammad Arshad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghulam%20Hussain%20Bhatti"> Ghulam Hussain Bhatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Qayyum"> Abdul Qayyum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Zinc-doped silica oxide nanoparticles having size 7.93nm were synthesized by the deposition precipitation method by using different solvents (acetonitrile, n-hexane, isoamylalchol). Biological potential such as antibacterial activities against Bacillussubtilusand Escherichia coli, and antifungal activities against Candida parapsilosis and Aspergilusniger were also investigated by Disc diffusion method. Different characterizations techniques including Fournier Transmission Infrared Spectroscopy (FT-IR), X-ray diffraction (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Thermo-gravimeteric Analysis (TGA), Atomic forced microscopy (AFM), and Dynamic Light Scattering (DLS) were used. FT-IR characterization confirmed the presence of metal oxide bond (SiO2) while XRD showed the hexagonal structure. SEM and TEM characterization showed the morphology of nanoparticles. AFM study showed good particle size distribution as depicted by a histogram. DLS study showed the gradual decease in the size of nanoparticles from 24.86nm to 13.24 nm. Highest antibacterial activities revealed by acetonitrile solvents (6%and 4.5%) followed by isoamylalchol (3% and 2.4%) while n-hexane solvent showed the lowest activity (2%and 1%) respectively. Higher antifungal activities exhibited by n-hexane (0.34 % and 0.43%) followed by isoamylalchol (0.27% and 0.19%) solvent while acetonitrile (0.21% and 0.17%) showed least activity respectively. Statistical analysis by using one-way ANOVA also indicated the significant results of both biological activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title="nanoparticles">nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=precipitation%20methods" title=" precipitation methods"> precipitation methods</a>, <a href="https://publications.waset.org/abstracts/search?q=antibacterial" title=" antibacterial"> antibacterial</a>, <a href="https://publications.waset.org/abstracts/search?q=antifungal" title=" antifungal"> antifungal</a>, <a href="https://publications.waset.org/abstracts/search?q=characterizations" title=" characterizations"> characterizations</a> </p> <a href="https://publications.waset.org/abstracts/73323/a-comparative-study-on-the-synthesis-characterizations-and-biological-antibacterial-and-antifungal-activities-of-zinc-doped-silica-oxide-nanoparticles-based-on-various-solvents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73323.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">207</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">183</span> Inhibitory Action of Fatty Acid Salts against Cladosporium cladosporioides and Dermatophagoides farinae</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yui%20Okuno">Yui Okuno</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariko%20Era"> Mariko Era</a>, <a href="https://publications.waset.org/abstracts/search?q=Takayoshi%20Kawahara"> Takayoshi Kawahara</a>, <a href="https://publications.waset.org/abstracts/search?q=Takahide%20Kanyama"> Takahide Kanyama</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Morita"> Hiroshi Morita</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Fungus and mite are known as allergens that cause an allergic disease for example asthma bronchiale and allergic rhinitis. Cladosporium cladosporioides is one of the most often detected fungi in the indoor environment and causes pollution and deterioration. Dermatophagoides farinae is major mite allergens indoors. Therefore, the creation of antifungal agents with high safety and the antifungal effect is required. Fatty acid salts are known that have antibacterial activities. This report describes the effects of fatty acid salts against Cladosporium cladosporioides NBRC 30314 and Dermatophagoides farinae. Methods: Potassium salts of 9 fatty acids (C4:0, C6:0, C8:0, C10:0, C12:0, C14:0, C18:1, C18:2, C18:3) were prepared by mixing the fatty acid with the appropriate amount of KOH solution to a concentration of 175 mM and pH 10.5. The antifungal method, the spore suspension (3.0×104 spores/mL) was mixed with a sample of fatty acid potassium (final concentration of 175 mM). Samples were counted at 0, 10, 60, 180 min by plating (100 µL) on PDA. Fungal colonies were counted after incubation for 3 days at 30 °C. The MIC (minimum inhibitory concentration) against the fungi was determined by the two-fold dilution method. Each fatty acid salts were inoculated separately with 400 µL of C. cladosporioides at 3.0 × 104 spores/mL. The mixtures were incubated at the respective temperature for each organism for 10 min. The tubes were then contacted with the fungi incubated at 30 °C for 7 days and examined for growth of spores on PDA. The acaricidal method, twenty D. farinae adult females were used and each adult was covered completely with 2 µL fatty acid potassium for 1 min. The adults were then dried with filter paper. The filter paper was folded and fixed by two clips and kept at 25 °C and 64 % RH. Mortalities were determained 48 h after treatment under the microscope. D. farina was considered to be dead if appendages did not move when prodded with a pin. Results and Conclusions: The results show that C8K, C10K, C12K, C14K was effective to decrease survival rate (4 log unit) of the fatty acids potassium incubated time for 10 min against C. cladosporioides. C18:3K was effective to decrease 4 log unit of the fatty acids potassium incubated time for 60 min. Especially, C12K was the highest antifungal activity and the MIC of C12K was 0.7 mM. On the other hand, the fatty acids potassium showed no acaricidal effects against D. farinae. The activity of D. farinae was not adversely affected after 48 hours. These results indicate that C12K has high antifungal activity against C. cladosporioides and suggest the fatty acid potassium will be used as an antifungal agent. <p
