Effect of Myrothecium sp. cellulase on different types of cellulose and cellulosic materials.
Three types of cellulase preparations were applied to different types of cellulose and cellulosic materials. The action of these types of cellulase on cellulose powder was increased with the increase of enzyme concentration. Both carboxymethyl cellulose (CMC) and sodium carboxymethyl cellulose (Na-CMC) released high amounts of reducing sugar as affected by cellulase application. Different types of paper pulp were moderately hydrolyzed, while agricultural wastes were slightly hydrolyzed. Vegetable and fruits cellulose were equally hydrolyzed but at low rate. Pretreatment of cellulose or cellulosic materials by grinding or by swelling with phosphoric acid gave rise to increased hydrolysis by the enzyme. Cellobiose was detected chromatographically as an intermediate product of hydrolysis of both cellulose and carboxymethyl cellulose with glucose.
