Abstract

Bioethanol is a renewable energy source produced from fermentation of sugar released by saccharification of lignocellulosic materials. Pretreatment followed by enzymatic hydrolysis and fermentation has been reported as a very effective process for conversion of lignocellulosics to bioethanol. The present study investigates the effect of enzymatic hydrolysis using different enzymes like cellulase, xylanase and � glucosidase on alkali, acid and untreated water hyacinth and then optimizing the enzyme concentration. The study of the interaction among the three enzymes has been carried out to achieve the maximum total reducing sugar as well as xylose yield. The optimized predicted results of the influencing parameters for maximum yield of total reducing sugar are cellulase concentration of 15 U/g, xylanase concentration of 300 U/g and �-glucosidase concentration of 59.68 U/g, with a value of 431.421 mg/g and a desirability of 0.996.
