Abstract

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.

Keywords: Cellulose, enzyme, regenerated cellulose, wood pulp.
