| dc.description.abstract | Bioconversion of different carbohydrate substrates to ethanol and acetic acid was studied in glucose, fructose, jaggery, grape juice, kinnow pulp juice, sugarcane juice and apple juice by inoculating Saccharomyces cerevisiae G. Maximum ethanol production of 8.72% was observed with sugarcane juice followed by grape juice which was found to be 7.92%. After wine production, sugarcane wine and grape wine were further used for production of vinegar using Acetobacter aceti NRRL 746 with titrable acidity of 4.1 and 4.5, respectively after 25 days of incubation. Treated and untreated mixed agricultural waste was also used as substrate for the production of ethanol using cellulose degrading bacterial strain N11 and S. cerevisiae G via simultaneous saccharification and fermentation. Ethanol production was observed over a period of 7 days and the maximum ethanol production (0.3%) was observed in case of acid pretreatment followed by alkali pretreated mixed agricultural waste which was found to be 0.1%. Acid pretreated agricultural waste biomass was found to be promising substrate for ethanol production. | en |
