Fruits are natural sources of sugars harbored by different yeast strains. The local fruits were used as sources for the presence of diverse yeast strains with different morphology and biochemical characteristics. Out of the 122 isolates, 9 did not show any production of S02 in the media. These 9 strains were evaluated for stress tolerance assays and found that the strains L1 and J7 could tolerate ethanol, pH and temperature stress better than the other strains. These strains were also found to be amylolytic and potential ethanol producers. L1 and J7 were identified to be Saccharomyces cerevisiae isolate L1 and Saccharomyces cerevisiae isolate J7 and received Genbank accession numbers OK326788 and OK326764 respectively.
