The enzymatic digestibility of sugarcane bagasse was greatly increased by alkali (NaOH)-peracetic acid (PAA) pretreatment under mild conditions. The effects of several factors affecting the pretreatment were investigated. It was found that when bagasse was pre-pretreated by 10% (based on initial dry materials) NaOH with 3:1 liquid-to-solid ratio at 90 °C for 1.5 h and further delignified by 10% peracetic acid (based on initial dry materials) at 75 °C for 2.5 h, the yield of reducing sugars reached 92.04% by enzymatic hydrolysis for 120 h with...
