Rising fuel prices and declining fossil fuel reserves have compelled to search cheap sources of energy as biofuels. Biofuels like bioethanol reduce reliance on imported petroleum and decrease greenhouse gas emissions. Owing to depleting convention fuel reserves, there is global emphasis on ethanol production by microbial fermentation process. To ensure food security, bioethanol production from biomass which does not compete directly with food, is required. In this perspective, Deoiled rice bran (DORB), an agrowaste product represents a renewable and cheap non-food biomass resource. The present work was emphasized on ethanol production from DORB hydrolysate by Saccharomyces cerevisiae MTCC 4780 under optimized fermentation condition by specific gravity method. The result revealed maximum ethanol production of 9.68% at temperature 30ºC, fermentation duration of 48 h and pH 6. To the best of our knowledge, this is the first report on ethanol production from deoiled rice bran by yeast Saccharomyces cerevisiae MTCC 4780.
