英文摘要	The biorefinery process for sugarcane bagasse saccharification generally requires significant accessibility of cellulose. we reported a novel method of cascade cellulase enzymatic hydrolysis coupling with ultrafine grinding pretreatment for sugarcane bagasse saccharification. three enzymatic hydrolysis modes including single cellulase enzymatic hydrolysis, mixed cellulase enzymatic hydrolysis, and cascade cellulase enzymatic hydrolysis were compared. the changes on the functional group and surface morphology of bagasse during cascade cellulase enzymatic hydrolysis were also examined by ft-ir and sem respectively. the results showed that cascade enzymatic hydrolysis was the most efficient way to enhance the sugarcane bagasse saccharification. more than 65% of reducing sugar yield with 90.1% of glucose selectivity was achieved at 50 degrees c, ph=4.8 for 72 h (1200 r/min) with cellulase i of 7.5 fpu/g substrate and cellulase ii of 5 fpu/g substrate.
