Optimization of batch alcoholic fermentation of Cyperus esculentus

Journal Article:

Abstract

In our earlier work carried out on alcoholic fermentation of molasses the optimum sugar concentration was between 14.0 and 17.0% w/v sugars, beyond which ethanol content decreased drastically. However in the present work, ethanol concentration was still high at 20% w/v sugars. This suggested that the strain had enhanced tolerance to the adverse effects of C. esculentus medium than molasses. Substituting the calculated parameter values (a[sub 1]-a[sub 10]) and optimal conditions of pH, S and T into equation, the calculated yield equals 92.7%. We again tried to verify experimentally the reliability of the theoretical optimal values obtained. The concentration of ethanol obtained was 9.2 [+-] 0.2% v/v. This was higher than the maximum concentration recorded before simulation (8.9% v/v). The experimental yield obtained was 90.3 [+-] 1.6% which is in close agreement with the simulated value of 92.7%.
