Study on the optimal conditions of cellulase from termites The optimal pH when Cx from Reticulitermes flaviceps reacted with substrate sodium carboxymethylcellulose was between 5.0-7.4 and 5.0-6.2 when BG enzyme was reacted with substrate salicin, the relation between activities of enzymes and relevant pH values accorded with Quadratic models.

一、白蚁纤维素酶最适反应条件研究黄胸散白蚁 Reticulitermes flaviceps C_N酶与羧甲基纤维素钠(Carboxymethylcellulose sodium，CMC-Na)反应的最适pH值范围在5.0-7.4之间，BG酶与Salicin反应的最适pH值为5.0-6.2，2种酶的活性均与pH值符合二次项曲线模型。

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。
