摘要： Pretreatment of lignocellulose is a key step in a commercial biorefinery. To increase the cellulose mass fractions and enhance the enzymatic hydrolysis, sugarcane bagasse was pretreated with methods of dilute acid, dilute alkaline and acid coupled alkaline. The efficiency of these three methods is compared. After pretreated with acid coupled alkaline, the cellulose mass fraction in sugarcane bagasse increased from 54.43%% to 93.53%. The initial hydrolysis rate for acid coupled alkaline treated sample was up to 15.13 times greater than those of untreated one. Thus, acid coupled alkaline pretreatment is a promising method for enhancing enzymes accessibility of lignocellulose.
