    Cellulolysis by Mucor pusillus.

    Abstract

    Culture filtrates of Mucor pusillus NRRL 2543 contained hydrolytic enzymes that attacked native cellulose, acid-swollen cellulose, carboxymethylcellulose, and cellobiose. The distribution profiles of cellulolytic and beta-glucosidase activities after gel filtration on Sephadex G-75 showed the presence of several active peaks. Glucose was the only product of hydrolysis when native cellulose was used as the substrate. Acid-swollen cellulose, when treated with cellulase free of beta-glucosidase activity, gave rise to glucose, cellobiose, and at least two higher molecular weight components which were also hydrolyzed in turn to cellobiose and glucose. The presence of a multiple cellulolytic enzyme system was indicated, the components of which may have specific roles in the degradation of cellulose.
