Therefore, the present study was attempted to study physicochemical properties, antioxidant and antimicrobial activities of mango seed kernel and peel wastes. The result of physicochemical properties indicated that significantly higher oil yield (38.75±1.77), specific gravity (0.86±0.04), acid value (2.66±0.20) and free fatty acid value (1.34±0.12); and higher DPPH (16.70±0.70) antioxidant activities were recorded for mango seed oil extract. However, significantly higher hydrogen peroxide scavenging activity (HPSA, 31.10±1.70) and ascorbic acid (43.00±2.73) were recorded for fruit peel oil extract. Stronger antibacterial activity with maximum zone of inhibition (16.50 mm), minimum inhibitory concentration MIC (0.10µl/ml) and corresponding minimum bactericidal concentration MBC (0.20 µl/ml) was recorded for seed oil extract against S. aureus. Stronger antifungal activity with maximum zone of inhibition (16.47 mm), MIC (0.05 µl/ml, the least value) and MFC (0.10 µl/ml) for seed oil extract against C. albicans. It can be concluded from the results of present study that seed oil extract was found to be more effective antioxidant and antimicrobial potential than peel oil extract in mango (M. indica L.)\u0000 ","PeriodicalId":153699,"journal":{"name":"Fungal Territory","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125159480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wild yeasts could provide an alternative to common domesticated brewer’s yeasts by offering a new range of sensory characteristics and improved performance in harsh brewing conditions such as high gravity and high ethanol concentration in wort. High gravity brewing is practical and profitable as it increases production capacity, therefore reducing investment and energy costs. Exploiting the existing natural diversity could lead to finding superior industrial yeasts as well as a better understanding of biodiversity. The aim of the present study was to determine if wild yeast strains isolated from the ecosystem at a regional level (Northeast Mexico) showed favorable characteristics in the brewing process. Sixty-three yeast isolates were obtained from diverse samples including flowers and fruits. Five isolates were selected after three rounds of beer fermentation based on their sensory characteristics. Tests to assess growth over time, flocculation potential, ethanol yield, osmotolerance and ethanol tolerance were applied to two reference yeasts (commercial beer brewing strains) and to the selected isolates of interest which were identified as Saccharomyces cerevisiae by MEX67 amplification and ITS sequencing. The results indicated that the selected wild isolates exhibit characteristics comparable to commercial reference strains in terms of growth and stress tolerance.","PeriodicalId":153699,"journal":{"name":"Fungal Territory","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122398319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fungi were isolated from palm-oil mill wastes and screened for their lipid-hydrolyzing potentials. Lipase production and activity characteristics were determined using different substrates. Sixteen, out of the 75 fungi isolated, exhibited lipolytic characteristics. Yeast isolate PL2 gave the highest zone of hydrolysis (44.5 mm) and was identified as Kodamaea ohmeri. This yeast was cultured under diverse media conditions for lipase production and the enzyme produced under each physicochemical condition was determined spectrophotometrically. The optimum parameters for lipase production (1% Tween-80, Ca2+, peptone, 37°C and pH 6) were used to produce lipase which was further purified through (NH4)2SO4 precipitation, membrane dialysis and gel chromatography. The activity of the partially purified lipase increased progressively with each purification stage. The lipase had optimum activity at 50oC and was alkalophilic with peak pH for enzymatic hydrolysis at 8.0. The lipase was supported by 0.5% concentrations of SDS and Triton X-100 (129.9 and 129.4%, respectively), and a 100-fold activity increase with 0.5% Tween-80. Lipase activity was augmented by Manganese and calcium ions (10 mM) but inhibited by NH4+, Fe3+ and Na+. The use of Tween-80 resulted in increased enzyme yield as well as better enzyme characteristics compared to other substrates. The knowledge obtained in this study may be harnessed for commercialization of Kodamaea ohmeri lipase.","PeriodicalId":153699,"journal":{"name":"Fungal Territory","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130774264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most often, these contaminants are fungi and molds-based microbes producing toxic contaminants that result in severe deterioration of some of the quality characteristics of these agro products. These toxic metabolites are called mycotoxin. Many fungi toxic in food and feed are known to be hazardous to human and animal’s health. To prevent the contamination of mycotoxins in foods and feeds, primary, secondary, and tertiary methods are required. Similarly, certain treatments are equally necessary to control the continuous growth of these toxins in the products. This study deals with the review of these various preventive and corrective methods with the view of providing useful insight to the current practices of mitigating the production and contamination of mycotoxins in food and feed products. The study discusses the tendency of an integrated Taguchi model for predicting or studying mycotoxin through the combination of various preventive activities to emerge the optimum preventive procedure.","PeriodicalId":153699,"journal":{"name":"Fungal Territory","volume":"18 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130392208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The direct plate enrichment counts and filtration technique recorded the highest number of counts (59 % and 32 %) respectively. The sabauraud dextrose Agar (SDA) was observed as the medium that recorded the highest colonies (60 cfu/100 ml) for incubation period of 5 d at 30 oC. Six different fungal taxa were recovered from the three examined sites (ST1, ST2 and ST3) and the ST3 was reported to have the highest number of isolated species. However, certain fungi were observed to be more distributed than others, specifically in species of Aspergillus and Penicillium which tended to be the most common. Although, species of other genera such as Acremonium sp., Rhizopus stolonifer, Mucor racemosus and Trichophyton sp. were also present but in low counts.
