Abstract


Cellulases are the hydrolytic group of enzymes, responsible for release of sugars in the bioconversion of the cellulosic biomass into a variety of value added industrial products. Fungal isolated cellulases are well studied and playing a significant role in various industrial processes. Enzymatic depolymerisation of cellulosic material has been done by the various fungal isolated enzymes. In the present study, the cultivation conditions for cellulase production from Aspergillus species were optimized. Optimization of scarification conditions such as time course, inoculum size, carbon source and concentration, nitrogen source, various pH levels were performed for the production of extracellular carboxymethyl cellulase and endoglucanase enzyme. The result exhibited, 15 % inoculums size, corncobs 2 % concentration, Urea and medium pH 7 at 30oC supported high yield of carboxymethyl cellulase (38.80 U/ml/min) and exoglucanase enzyme (10.94 U/ml/min) through a submerged fermentation (SmF). In future biotechnological applications in cellulase enzyme production attain a vital role to obtain high degradable yield.
