Production of some enzymes in the autolysis of the white-rot fungus Coriolus versicolor in fermenter.

The autolysis and production of some extracellular enzymes by Coriolus versicolor was studied in submerged cultures. After 48 days of incubation the fungus lost 31% of its maximum dry weight. 1.3-beta-glucanase was excreted at the beginning of autolysis and proteases were present during the course of the experiment. On the other hand, laccase was produced in very small amount in the first days of incubation, reaching the maximum activity at the 8th-day of autolysis.
