Improvement of the capacity to hydrolyze corncob residues through deciphering the lignocellulolytic enzyme system of a hyper-cellulolytic mutant strain Trichoderma reesei CU7-4.

ABSTRACT:

Background

The degradation of agricultural wastes is crucial for sustainable economic and environmental development, necessitating efficient cellulolytic enzymes to enable high-value bioconversion. The filamentous fungus Trichoderma reesei is a widely used cellulase producer for deconstructing agricultural wastes in biomass conversion. However, its enzyme system remains suboptimal and requires further refinement to achieve economical bioconversion of agricultural wastes.

Results

Herein, a hyper-cellulolytic T. reesei mutant strain CU7-4 derived from the industrial strain RUT-C30 was obtained by UV mutagenesis. When degrading the different pretreated corncob residues, CU7-4 exhibited a 20% improvement in saccharification efficiency compared to the parental strain RUT-C30. Fur
