Screening of mulberry yeast for the production of OC-amylase and ethanol

Abstract

Twenty isolates of yeast were isolated from the leaves of twenty mulberry varieties and used them for the production of ?-amylase and ethanol. Maximum production of ?-amylase was recorded in isolates. MY-1 (3.84 U/ml), W-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 7th day of incubation in Jaggery medium. Among the isolates, isolate MY-1 found to be superior for both ?-amylase and ethanol production. However, isolates MY-20 and MY-11 were found superior for only ethanol production. © Global Science Publications.
