Abstract
Twenty isolates of yeast were isolated from the leaves of twenty mulberry varieties and used them for the production of cc-amylase and ethanol. Maximum production of cc-amylase was recorded in isolates. MY-1 (3.84 U /m1), MY-5 (1.60 U/ml) and MY-6 (1.22 U/ml) at 30°C in yeast extract triptone medium. Isolates MY-20 (2.77%) MY-11 (2.72%) and MY-1 (2.52%) produced maximum ethanol on 7h1 day of incubation in Jaggery medium. Among the isolates, isolate MY-1 found to be superior for both cc-amylase and ethanol production. However, isolates MY-20 and MY-11 were found superior for only ethanol production.
