In order to introduce enzymatic saccharification into the production of ethanol fuels from cellulosic biomasses, significant reduction of the enzyme cost is required by dramatic improvement on saccharification of crystalline cellulose. Ammonia treatment of cellulose converts its crystalline structure from type I to type III(I). In the present work, the authors demonstrated that production velocity of glucose from crystalline cellulose III(I) by the optimized cocktail of PcCel6A and PcCel7D from Phanerochaete chrysosporium attained 155-times higher than that from Cellulose I by TrCel7A from Trichoderma reesei. Moreover production velocity of glucose from high density crystalline cellulose III(I) by PcCel6A only attained more than 400μM/min.
