木质素酶及其高产菌株选育的研究进展

Research Advances in Ligninase and Screening of Its High-yield Strains

木质素(lignin)是自然界中一种极其丰富的可再生资源。由于其结构的特殊性和复杂性,使其成为了影响植物纤维素利用率的关键因素之一。因此,如何利用木质素酶降解木质纤维素材料中的木质素,使纤维素从木质素和半纤维素的包裹中释放出来,实现纤维素的高效利用,已成为人们关注的热点。对木质素酶及其高产菌株的选育等方面进行了归纳和总结,以期为木质素降解的进一步研究提供参考。

Lignin is a renewable resource very abundant in nature.It is one of the key factors which affect utilization of plant cellulose because of its unique structure and complexity.Therefore,it has been a hot research spot to explore how to use ligninase to degrade lignin in lignocellulosic materials,release lignin from package of cellulose and hemicellulose and thus achieve efficient use of cellulose.This review concludes the studies on ligninase and screening of its high-yield strains in order to provide reference for degradation of lignin.
