Effect of culture conditions on the production of cellulases by Trametes trogii

Production of the components of the cellulase complex by Trametes trogii was investigated under different culture conditions. Endoglucanase, exoglucanase and beta-glucosidase were produced by Trametes trogii under shaken and stationary conditions using crystalline cellulose as the only carbon source...
