Abstract
Solid Substrate Fermentation system (SSF) was used to produce ethanol from various starchy substrates like sweet sorghum, sweet potato, wheat flour, rice starch, soluble starch and potato starch using thermotolerant yeast isolate (VS3) by simultaneous saccharification and fermentation process. Alcohol produced was estimated by gas chromatography after an incubation time of 96 hrs at 37 °C and 42 °C. More ethanol was produced from rice starch and sweet sorghum. The maximum amount of ethanol produced from these substrates using VS3 was 10 g/100 g and 3.5 g/100 g substrate (rice starch) and 8.2 g and 7.5 g/100 g substrate (sweet sorghum) at 37 °C and 42 °C respectively.
