Abstract

The action and effects of Trichoderma reesei cellulases (EG I, EG II, CBH I and CBH II) and their structural domains, i.e. core proteins and cellulose binding domains (CBD) on ECF bleached softwood kraft pulps were studied. The presence of CBD in the enzymes enhanced the enzymatic solubilization of cellulose from pulp. The CBD was also found to direct the site of the action of enzymes on pulp fibres. The effects of the core proteins on technical properties of cellulose resembled of those of the corresponding intact enzyme. However, the higher viscosity of the pulp after treatment with core protein than with intact enzyme suggests that CBD could play a role in the detrimental effect of cellulases on pulp viscosity.
