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.

摘要： The invention relates to a multi-enzymatic preparation containing the secretome of the CNCM I-4639 strain of
Aspergillus japonicus . This secretome, which contains in particular cellulases and hemicellulases, can be used for the saccharification of lignocellulosic substrates, in particular in combination with the secretome of
Trichoderma reesei .-
