Enhanced production of cellulase, hemicellulase, and β‐glucosidase by Trichoderma reesei (Rut C‐30)

Abstract

The Production of cellulases and Hemicellulases was studied with Trichoderma reesei Rut C‐30, This organism produced, together with high cellulase activities, considerable amounts of xylanases and β‐glucosidase. Three cellulose concentration (1, 2.5, and 5.0%) were examined to determined the maximum levels of cellulase activity obtainable in submerged culture. Temperature and pH profiling was used to increase cell mass to maximum levels within two days and thereby enhancing fermentor productivity at higher substrate levels. The effect of temperature, pH, Tween‐80 concentration, carbon sources, and substrate concentration on the ration of mycelial growth and extracellulose enzyme production are described.
