Abstract
Objectives: To increase the efficiency of enzymatic hydrolysis for plant biomass conversion into renewable biofuel and chemicals. Results: By overexpressing the point mutation A824 V transcriptional activator Xyr1 in Trichoderma reesei, carboxymethyl cellulase, cellobiosidase and β-d-glucosidase activities of the best mutant were increased from 1.8 IU/ml, 0.1 IU/ml and 0.05
