Factors influencing the production of cellulases by Sporotrichum thermophile.

ABSTRACT

Cellulase production and growth of a strain of Sporotrichum thermophile were studied by using a mineral salts medium supplemented with yeast extract and insoluble cellulose. The effects of cultural conditions, such as pH, nitrogen source, substrate concentration, and temperature, were examined. Maximum production of C1 and CX cellulases occurred at 45 C in 2 to 4 days, in the presence of 1% Solka/Floc as substrate, when NaNO3 or urea used as sources of nitrogen. Under these conditions, cellulolytic activity of culture filtrates appeared to be similar to that reported for Trichoderma viride grown in a favorable environment. However, comparable yields of cellulase were produced by S. thermophile in less than one-quarter the time required by mesophilic fungi.
