It is an alcohol obtained from fermentation of sugars, starches or from cellulosic biomass. This research aims to develop and assess an enzyme based biomass to ethanol conversion process, which employs agricultural waste materials, as alternative sources of cellulosic material feedstock (rice bran and groundnut shells) Cellulase producing organism Aspergillus niger and ethanol producing organism Saccharomyces cerevisiae are used in this process to digest the cellulose and to convert them into alcohol. This method implies ethanol conversion in an easy, less expensive method. The cellulosic biomass is pretreated by acid and alkali methods. Simultaneous Saccharification and Fermentation (SSF) process is preferred for this production. The physio chemical parameters (pH and temperature) which influences the production of ethanol were optimized.
