ABSTRACT:
The present invention pertains to a method of converting cellulose to glucose by treating a pretreated lignocellulosic substrate with an enzyme mixture comprising cellulase enzyme and a modified CBHO, wherein the modified CBHI is present in the enzyme mixture at an amount relative to all CBHI-type enzymes from about 15% to about 100% (w/w),depending upon the modified CBHI used. The pretreated lignocellulosic substrate is selected from the group consisting of agricultural residues, residues after starch or sugar removal dedicated ethanol crops forestry products, and pulp and paper products, or combinations thereof.
