| 摘 要： | 木质素酶降解木质纤维素材料中的木质素，使木质素-半纤维素-纤维素结构解体，纤维素得以暴露出来供后续步骤处理。它广泛应用于生物制浆、生物漂白、废水处理等工业过程中。由于近年利用可再生木质纤维素材料用酶法水解生产酒精成了研究热点，因而作为纤维素材料生物转化工艺预处理过程中的关键角色，木质素酶也极大地唤起人们的研究兴趣。本文介绍了木质素与白腐真菌（phanerochaete chrysosporium）木质素降解酶系的特征以及锰过氧化物酶、木质素过氧化物酶、漆酶等3种木质素酶的催化作用机理，归纳了目前流行的木质素酶产生菌的筛选方法及近年来从自然界筛选木质素酶高产菌的种类，并对产木质素酶野生菌株的诱变育种与基因工程改造的进展进行了阐述。

| Abstract: | Ligninolytic enzyme system can degradate the lignin in lignocellulose materials and further destroy the lignin-hemicellulose-cellulose structure of lignocellulose materials;As a result, cellulose is exposed thus further be-ing processed.Ligninolytic enzyme system is widely used in bio-pulping, bio-bleaching, wastewater treatment et al.because reproducible lignocellulose material-based alcohol production using enzymatic hydrolysis technology is increasingly research focus, ligninolytic enzyme system, as a cr... |
