Cellulase is the most abundant biomass; it is renewable and in-expensive for the bioconversion to bio-fuels and bioproducts. There are many sources to derive cellulosic biomass from such municipal waste, agricultural residues, forestry or pulp and energy crops. Cellulose is commonly degraded by enzyme called cellulase. Cellulase refer class of enzymes produced chiefly by fungi, bacteria and protozoans that catalysis the cellulose. Due to its diversity of their application cellulase have attracted much interest. The major industrial application of cellulases are in textile industry for bio-polishing of fabrics, house-hold laundry detergents for improving fabrics softness and brighteness. Cellulases hydrolyze cellulose and produces primary products glucose, cellbiose and cello-oligosaccharides. There are three types of cellulase enzymes [cellbiohydrolase(CBH), endo-β1,4- glucanase(EG) and β- glucosidase]. Enzymes within these classification can be separated into individual components, such as microbial cellulase composition may consist of one or more CBH component, one or more EG components and possibly β- glycosidase. Commercial production of cellulase has been tried by either solid or submerged culture including batch, fed batch and continuous flow process. Media used in cellulase fermentation contain cellulose in different degrees of purity, or as raw lignocellulosic subtrates, which is especially true in solid state fermentation.
