ABSTRACT

 

The agricultural crop like Maize is the most abundant cereal crop grown in India. It also produces the agro wastes like corncobs. It is used for the production of bio ethanol. Aspergillus flavus isolated locally was used to hydrolyze the corncobs into simple sugars (5%). Thus pretreated simple sugars are filtered and the filtrate was inoculated with Saccharomyces cerviceae for further fermentation at different pH and temperature. The rate of degradation effect of Aspergillus flavus and Saccharomyces cerviceae was enumerated using various parameters viz., temperature, pH, etc. The preliminary results using corn cob as biomass show the production of 3.2 % ethanol at pH 5.0 and temperature 30°C.
