摘要
木质纤维生物质是地球上最丰富的可再生生物质资源,可为造纸、化工、纺织和生物能源等工业提供重要的原材料。木质纤维生物质主要包括木质素、纤维素和半纤维素三种生物多聚物成分。如何利用分子手段改造这些生物聚合物,提高它们的工业利用率是目前高度关注的问题。综述了近年来木质纤维多聚物在生物合成与改造方面的研究进展,展望了利用分子技术改造植物木质纤维生物质实现其高效利用的前景。
Lignocellulosic biomass, the most abundant renewable resources on the earth, provides main raw materials for production of paper, chemicals, textile products, bioenergy and so on. Lignocellulosic biomass mainly consists of three biopolymers: cellulose, hemicellulose and lignin. The utilization of these biopolymers is determined by their compositional and structural properties. Modification of the biopolymers through molecular technology promises more efficient utilization of lignocellulosic biomass. This review summaries the recent progress on the biosynthesis and molecular modification of three biopolymers and offers perspectives of molecular technology for lignocellulosic biomass modification.
