摘要: 以自合成的木质素磺酸钠基固体酸(Sl-C-S-H2O2)为催化剂,并耦合纤维素酶实现玉米芯的两步水解建立糖平台。考察预处理条件对木糖收率的影响,最高木糖收率可达83.4%;在国产纤维素酶的作用下,48 h葡萄糖收率即可达92.6%,两步反应的总还原糖收率达88.1%。

Abstract: In this work, the hydrolysis of corncob was combined with pretreatment by self-synthesized carbon-based solid acid catalyst and subsequent enzymatic hydrolysis of treated residue by cellulase. Through the optimization of the pretreatment reaction condition, the highest xylose yield of 83.4% was obtained. Then, the treated residue was enzymatic hydrolysis by domestic cellulose with the glucose yield of 92.6% was obtained at 48 h and the total yield of reducing sugar up to 88.1% was obtained within these two-step hydrolysis process.

Key words: biomass, saccharification, enzymatic hydrolysis, carbon-based solid acid, pretreatment
