The biocatalyzed characters of the purified cellulases were investigated with the CMC-Na as substrate. The most appropriate catalyzed temprature for cellulase 1 is 60 "C,and 65 for cellulase 2. The two enzymes have the extreme stability at the temperatures no more than 50.The CMC-Na has the protective effect on the cellulase. The pH stability range of cellulase 1 is 4 ~ 8, and 6-9 for cellulase 2. Zn2+, Ca2+, Mg2+, K+, Li+can ativate cellulase 1. K+, Li"1 can ativate cellulase 2. Cellulase 1 can mainly decompose CMC and salicin. Cellulase 2 can decompose not only CMC and salicin, but other substrates feebly.

以羧甲基纤维素为底物时，酶1的最适催化温度为60℃，酶2的最适催化温度为65℃，在50℃以下稳定性较好，底物对酶有较强的保护作用；酶1和酶2的最适pH分别为5.5和5.5～6.0，酶1的pH稳定性范围为4～8，酶2的稳定性范围为6～9；Zn~(2+)，Ca~(2+)，Mg~(2+)，K~+，Li~+对酶1有激活作用，K~+，Li~+对酶2有激活作用；酶1主要对CMC和水杨素有分解作用，对其它底物几乎不分解；酶2除了可以分解CMC和水杨素外，对其它底物也有微弱的分解作用。
