Abstract:
:Cultures of Sclerotium rolfsii and Trichoderma viride together in autoclaved soil were assayed at intervals during 8 days of incubation for proteolytic activity (PA) of T. viride. Significant proteolytic activity was detected only in soil containing T. viride (i.e., T. viride alone or S. rolfsii + T. viride); greatest activity occurred between 3 and 4 days after infestation and declined rapidly thereafter. Maximal PA in the mixed-culture soil was accompanied by an increase in soil pH. optimal pH values for PA was 5.5-6.5 with a maximum at 6.0.
