Enzymatic Hydrolysis of Softwood and Hardwood Regenerated Celluloses

Regenerated celluloses from Kraft wood pulps (from hardwoods and softwoods) were hydrolysed by means of cellulase of Trichoderma reesei. Our results highlighted that a 75% hydrolysis yield was reached for hardwood regenerated cellulose (HRC) and 90% for softwood regenerated cellulose (SRC). Crystallinity indices from X-Ray diffraction patterns were used to measure hydrolysis rate of crystalline and amorphous regions. Addition of β-glucosidase to the enzymatic complex of Trichoderma reesei was confirmed to enhance yields of hydrolysis.
