Heat resistance of genus Byssochlamys isolated from bottled raphia palm wine

Bottled raphia palm wine was cultured in a laboratory medium amended with 0.5% acetic acid (pH 4.8). Two cultures of identified heat resistant yeast (HRY) and one unidentified yeast species were isolated. Cultures of the isolates grown on potato dextrose agar for 10 days at 26°C, survived pasteurization temperature at 80°C for 20 min and 85°C for 15 min. Of these HRY identified...

Isolation and random amplified polymorphic DNA (RAPD) analysis of wild yeast species from 17 different fruits

The purpose of this study was to isolate the wild yeast strains present on different fruits and performing random amplified polymorphic DNA (RAPD) analysis to know the genetic inter relationship between different isolated species. Seventeen different fruit namely mango, apple, banana, black grapes, sapotae, orange, plum, jamun, pear, cherry, dates, pomegranate, figs, papaya, pineapple, green grapes and raisins were used...

Influence of bacteria and protozoa from the rumen of buffalo on in-vitro activities of anaerobic fungus Caecomyces sp. isolated from the feces of elephant

Anaerobic fungal isolates Caecomyces sp. from the feces of elephant andOrpinomyces sp. from buffalo rumen were co-cultured in-vitro with rumen bacterial and protozoal fractions collected from buffalo to observe the possible fate of these fungi in the rumen, if inoculated as microbial-feed supplements. When co-cultured together or separately with rumen bacteria and protozoa, Caecomycessp....

Influence of culture media on growth, colony character and sporulation of fungi isolated from decaying vegetable wastes

The mycelial growth rate, colony character and sporulation pattern of ten fungal isolates, grown on three different culture media viz., Potato Dextrose Agar (PDA), Czapek’s Dox + Yeast Extract Agar (CYA) and Lignocellulose Agar (LCA) were observed after seven days of incubation at 25±1οC. The colony diameter, culture characteristics (texture, surface and reverse colouration, zonation) and...
