CUTTING AND CRUSHING PRETREATMENT OF CELLULOSIC MATERIAL FOR ENZYMATIC SACCHARIFICATION

摘要

PURPOSE:To improve the enzymatic saccharification ratio of a cellulosic material, by cutting and crushing a cellulosic material mechanically with a rotary cutter, and carrying out the enzymatic saccharification. CONSTITUTION:A cellulosic material is conditioned to a water-content of preferably =40wt%, especially about 10wt% corresponding to the air-dried state, and cut mechanically at room temperature with a rotary cutter having a rotary rod furnished with plural edges at the circumference. The cut cellulosic material is subjected to the conventional enzymatic saccharification process.
