| 摘 要： | 采用人工土壤试验法,研究了在不同Cd暴露环境中赤子爱胜蚓(Eisenia fetida)体内纤维素酶活性变化的响应。结果表明在短时间内随着Cd浓度增大,蚯蚓体内纤维素酶活性有明显的下降趋势,表现为纤维素酶活性有一定程度的抑制;随着Cd浓度增加和染毒时间延长,蚯蚓体内纤维素酶活性表现出不同程度的升高,在高浓度Cd暴露环境中,Cd对蚯蚓体内纤维素酶活性有显著的诱导作用。

| Abstract: | The research explored response of cellulase in Eisenia fetida in soils with Cd at different concentrations, as per artificial soil test. The results indicated that as Cd concentration increased, the activity of cellulase was decreasing in a short peri- od, which suggested that cellulase activity was inhibited to certain extent. As Cd concentration and the treatment period grew, the activities increased in varying de- grees. With Cd at a high concentrate, Cd had a kind of induction effects on cellu- lase activity in earthworms. |
