BETA-GLUCOSIDASE VARIANTS HAVING IMPROVED ACTIVITY, AND USES THEREOF

摘要

The present invention relates to the expression and optimization of enzymes involved in lignocellulosic biomass decomposition. The present invention relates more specifically to beta-glucosidase variants comprising at least one deterioration among the amino acids located at positions 225, 238, 240, and 241 according to the numbering in SEQ ID NO:2 of beta-glucosidase for Trichoderma reesei, and also relates to the use of said variants, having improved performance, in methods for cellulose decomposition and biofuel production.
