Abstract
The factors influencing cellulase activity of Chaetomium spirale (Zopf) grown on cotton fibre were examined. Culture filtrates of the oraganism gave highest activities when grown for eight days in a stationary liquid culture at 30°C in a cellulose-mineral medium with an initial pH value of 4.2. Addition of small quantities (0.1% w/v) of proteose peptone of casein hydrolysate markedly improved enzyme activity and so did the weekly transfer to a fresh cellulose-mineral medium of the fungus inoculum.
