Research progress of cellulase production by Trichoderma reesei

Trichoderma reesei has many advantages in cellulase production, such as the extensive of growth environment, good stability, efficient enzyme production, reasonable mold structure of cellulase components. The screening method of high cellulase producing strain by Trichoderma reesei was described, including nature selective breeding, mutation breeding, protolast fusion, genetic engineering, enzyme modification and so on. Furthermore, a brief exposition was made in the application and outlook of cellulase enzymes produced by Trichoderma reesei in food, animal feed,medicine and other fields.
