Cellulase treatment for decreasing viscosity of cellulose (dissolving pulp) is a promising approach to reduce the use of toxic chemicals, such as hypochlorite in the dissolving pulp manufacturing process. In this study, the use of an endoglucanase-rich cellulase to replace the hypochlorite for this purpose and its improvements of the Fock reactivity were investigated. The results showed that at a...
This study was to determine the effect of fiber hornification on the viscosity decrease of prehydrolysis kraft-based dissolving pulp using a commercial endoglucanase-rich cellulase. Three pulp samples, namely never-dried (ND), air-dried (AD) and oven-dried (OD), were used. The results showed that the enzymatic performance in the viscosity decrease was affected by the fiber history: the ND sample showed...
