ABSTRACT

The utilization of ethanol as an alternative fuel has escalated recently because of some conceivable reasons. Bioethanol can be produced by fermenting sugars from biomasses and used as fuel for vehicular engine internal combustion. Currently, most of the conventional ethanol fermentation feedstocks are relying on agricultural crops, such as starch-based crops and sugar-based crops. Saccharomyces sp were isolated from different fruits, including (i) White Grapes, (ii) Black grapes, (iii) Sapota. The isolated Saccharomyces sp were screened for production by qualitative method. Ethanol were produced by using corn cob as substrate through fermentation process. Optimization were studied by employing pH, temperature and inoculum size. The pH 5.0 showed 1.03% of ethanol production. The temperature (300C) and inoculum size (1.0 ml) showed 1.23% and 1.54% of ethanol were produced.

Keywords: Bioethanol, Corn cob, Saccharomyces sp , optimization studies and Submerged fermentation.
