Abstract
Abstract The effect of varying concentrations of d -glucono-1,4-lactone (2.6–8.4 m m ), a potent inhibitor of β- d -glucosidase, on the production of carboxymethylcellulase (CMCase), 4-nitrophenylcellobiosidase (pNPCase) and true cellulase by Clostridium thermocellum strain YS was studied in the presence of cellobiose and Avicel. It was found that d -glucono-1,4-lactone up to 8.4m m had no effect on the production of CMCase, pNPCase and true cellulase by C. thermocellum grown either on cellobiose or on Avicel. Thus, it was concluded that cellobiose rather than its transglycosylated product is the inducer of the cellulase system in C. thermocellum .
