摘　　要：纤维素内切酶(EG)被广泛应用于食品、造纸、纺织、酿造等行业,受到人们的广泛关注。纤维素内切酶,即内切-β-1,4-葡聚糖酶(EG),是纤维素酶系的重要组成之一,能够特异性切割纤维素内部的无定型区,从而启动纤维素的分解;其来源十分广泛,在一些古细菌、细菌、真菌中均有存在。目前,CAZymes数据库中已有数百种EG得到表征,且有相当一部分性能优异的EG被应用于工业生产中。因此,对EG的来源、分类、结构及应用等方面进行了综述,对探究EG的作用机制及应用价值具有重要意义。Endocellulase(EG)has been widely used in food,papermaking,textile,brewing,and other industries,and had attracted wide attention.Endo-β-1,4-glucanase(EG)is one of the important components of cellulase,which can specifically cleave the amorphous region of cellulose to initiate cellulose decomposition.It has a wide range of sources,including some archaea,bacteria,and fungi.At present,hundreds of EGs have been characterized in the CAZymes database,and a considerable number of EGs with excellent performance were used in the industry.However,the complexity of cellulosic substrates limits the further application of EG.Therefore,this paper reviewed the source,classification,structure,and application of EG,which was of great significance for further exploring the mechanism and application value of EG and solving existing problems.
