GLUCOSE METABOLISM IN PENICILLIUM DIGITATUM

Abstract

The utilization of glucose by proliferating Penicillium digitatum cells has been examined by the radiorespirometric method. Glucose is catabolized by this organism mainly (77%) by way of the Embden–Meyerhof–Parnas pathway in conjunction with the tricarboxylic acid cycle and CO 2 fixation processes. A minor portion (23%) of the administered glucose is utilized via an oxidative route involving a C 1 –C 5 cleavage. Pathway estimations on the basis of CO 2 production and glucose consumption were also discussed.
