The rate of synthesis of Pyrenochacta terrestris cellulase was determined on the substrates of glucose, cellulose, and cellulose + glucose. Enzyme production was rapid on cellulose, almost negligible on glucose, and intermediate on cellulose + glucose. On the latter substrate, cellulase appeared after the near exhaustion of glucose. The authors suggest that extremely low concentrations of soluble carbohydrate regulate cellulase synthesis.
