A novel process by using bisulfite pulping method for bagasse pretreatment to improve enzyme adsorption on fibers and their enzymatic hydrolysis were studied.The cellulase adsorption on the pretreated bagasse was measured by spectrophotometry with a kinetic model,and then the relationship between cellulase adsorption and the yield of hydrolysis was discussed.The results show that the rising of temperature of sulfite pretreatment and increasing of the dosage can improve the cellulase adsorption on the pretre...
