[Effect of carbon and nitrogen sources on the cellulolytic activity of Trametes trogii].
Trametes trogii was grown in a liquid synthetic medium containing different carbon and nitrogen sources. Enzymatic activities of cellulases (endoglucanase, exoglucanase and beta-glucosidase) were measured in culture supernatants. Organic nitrogen sources were the most favourable for growth and cellulase production. Increasing nitrogen concentrations also increased cellulase production. Among carbon sources, crystalline cellulose, cellobiose and a mixture of carboxymethylcellulose and cellobiose induced maximal endoglucanase production. The optimal concentration of the carbon source was 10 g/l.
