In this research, the activities of CWDE were measured by saccharifying according to the theory that red-brown amino compounds were produced when 3, 5-dinitro salicylic acid and aldehyde were heated together. And the testing conditions were made clear. The activity of Cx should be tested with optimal temperature of 50℃, optimal pH of 4.8, incubation time of 30 min, and optimal substrate of 0.6% CMC-Na. Due to the heat-libality, Cx should be sterilized more than 10 min. The testing conditions of the activity ofβ-G were almost the same with Cx except the substrate of 0.5% salicin and the sterilization time of more than 15 min.

Salicin：水杨苷
1828年慕尼黑大学的药剂学教授约翰.毕希纳(JohannBuchner)从止疼用的植物中分离出了很少量的苦味黄色针状晶体,他把这种晶体命名为水杨苷(salicin).而早在1826年,两个名叫布拉格奈特利(Brugnatelli)和方塔纳(Fontana)的意大利人就得到了纯度不高的水杨苷.
