Effects of cellobiose and glucose on cellulose hydrolysis by both growing and resting cells of Bacteroides cellulosolvens.

Abstract:

:The cellulase system of Bacteroides cellulosolvens was subjected to both catabolite repression and feedback inhibition by cellobiose. Cellulose-solubilizing activity was 50% inhibited at a cellobiose concentration of 2.6 g/L and completely inhibited by 12 g/L. Glucose at 12 g/L (the highest concentration tested) had no effect on cellulase activity. Supplementation of B. cellulosolvens cellulase with beta-glucosidase resulted in increased conversion of cellobiose to glucose; however, a constant cellobiose pool size of approximately 7 g/L was maintained.
