摘要
木质纤维素类生物质复杂的理化组成和多级结构不均一性,是阻碍其经济高效水解产糖的关键。尽管辅助一些经济有效的预处理手段,但单一纤维素酶实现木质纤维素-糖转化依旧难以跨越酶解成本过高的障碍。综述了由纤维素酶和辅助酶(外源性水解酶)组成的复合酶在饲料工业、淀粉加工工业及其副产物附加值提取等方面的研究和应用情况,并对复合酶在木质纤维素-糖平台的未来发展进行了展望,为未来的纤维质生物炼制在提高酶解效率和降低酶解成本方面提供一种新思路。
The complicated chemical composition and recalcitrant heterogenic structure of lignocellulosic biomass feedstock have frustrated the economic and efficient enzymatic hydrolysis of it. In spite of assisting some effective pretreatment methods, it is still cost-expensive to achieve the lignocellulose-to-sugar conversion only with the cellu- lase. In this Review, the enzyme complexes comprising cellulase and its assisting enzymes （some hydrolytic en- zymes） applied in pulp and papermaking, feed industry, isolation and extraction of plant components, starch pro- cessing and value-added extraction of starchy industrial byproducts were focused on. The future application of en- zyme complexes in lignocellulose-to sugar platform was prospected, which gave a new insight to enhance the effi- ciency and reduce the cost of enzymatic hydrolysis for the lignocellulosic bio-refinery.
