| Abstract: | The fermentation variables (temperature, pH and agitation) were optimized by response surface methodology (RSM) alogorithm, Design Expert 7.1 and a response quadratic model was generated that revealed a correlation between all these parameters and also provided 23 solutions for process validation. Under the optimized conditions, the effect of inoculum size revealed 5.0 and 2.5% (v/v) of Saccharomyces cerevisiae Y-2034 and Pachysolan tannophilus Y-2460, respectively as optimum for sequential fermentation. The optimization of sequential fermentation led to improvement in total ethanol yield from 20.61 to 22.24 g L-1. |
