The A. niger was selected for saccharification as it is cellulolytic in nature and can hydrolyze cellulose
present in the substrates to simple sugars. Generally this step is carried out by commercially available cellulase
enzyme which is very expensive. In our study an attempt was made to design an economical process by the use
of intact fungal organism as a source of cellulase enzyme instead of commercially available enzyme. As A.niger
grows on the cellulosic substrates and hydrolyzes cellulose of the substrate and release simple sugars which can
be fermented to produce bioethanol.
