Utilization of cellulosic wastes with biosynthesis of cellulase

The influence of different pretreatment methods of cellulosic materials to increase the productivity of the cellulase biosynthesis was analyzed. The most effective pretreatment method for cotton cellulose is the thermomechanical destruction in a worm extruder (5-15 minutes) with hydrolysis catalyts. The enzymatic saccharification degree was increased about 4 fold. Utilizing a pretreated cellulose an increase of 70-120% in C sub(1)-activity was found besides their level was stabilized in higher values. It was demonstrated that enzymatic hydrolysis parameters would be applied as model for biochemical utilization of cellulosic materials in the biosynthesis of cellulases.
