用不同的提取微生物酶处理不同的纤维素原料。由酶处理引起的纤维素结构和性质的变化取决于组成、酶的类型和纤维素材料的类型。内切葡聚糖酶和粗纤维素酶对纤维素的结构都有明显的影响。发现晶体结构的变化在酶解过程中优先攻击纤维素I的（0 0 2）晶面。(C)2004年爱思唯尔公司All rights reserved.
Different cellulosic materials were treated with different extraceller microbial enzymes. Changes in structure and properties of the cellulose caused by enzymatic treatment depend on the composition, the type of enzyme and the type of cellulosic materials. Both endoglucanase and crude cellulase have pronounced effects on the structure of cellulose. The variation of crystal structure was found to attack preferentially the (0 0 2) crystal planes for cellulose I during enzymatic hydrolysis. (C) 2004 Elsevier Inc. All rights reserved.
