中文摘要：

分离到的1株真菌月状旋孢腔菌（Cochlioboluslunatus）Cd7，可在2000mgL。镉（Cd^2＋）液体培养液中存活，显示菌株具有较强的抗镉能力．吸附实验结果表明，菌丝球投加量为2gL^-1时，无论菌丝球灭活与否，菌株对Cd^2＋的吸附率随Cd^2＋浓度的升高而下降，吸附量随Cd^2＋浓度的升高而增加．当Cd^2＋浓度100mgL。以下时，灭活菌丝球对Cd^2＋的吸附量为活菌丝球的70％以上．菌丝球投加量为0．5．3．0gL^-1，菌株对Cd^2＋的吸附率随菌丝球投加量增加而增加，吸附量随菌丝球投加量的增加而急剧减少pH6.0、金属离子浓度为100mgL。时，菌丝球对单一Cd^2＋、Pb^2＋、Cu^2＋和Zn^2＋离子的平均吸附量顺序为：Cd^2＋〉Zn^2＋〉Cu^2＋〉Pb^2＋．金属离子的共存抑制菌体对各离子的吸附，离子种类越多，抑制作用越明显.图3表2参23

英文摘要：

A strain of Cochliobolus lunatus with high cadmium resistance was isolated and found to survive in liquid medium containing 2 000 mg L^-1 cadmium. Results showed with 2 g L^-1 mycelial pellets, the adsorption rates of Cd~＋ decreased with the increasing Cd concentration, but the adsorption quantity increased with the increase of Cd concentration. Inactivated myceliums could adsorb 70% more Cd than living ones when Cd was less than 100 mg Ll. When mycelial pellets was added in the range of 0.5-3.0 g L^-1, the adsorption rates of Cd^2＋ increased with the increasing mycelial pellets, but the adsorption quantity decreased sharply. Mycelial pellets showed different adsorption ability for different metals with the order of adsorption quantity of Cd^2＋ 〉 Zn^2＋ 〉 Cu^2＋ 〉 Pb^2＋ when single metal was in the concentration of 100 mg L^-1 at pH 6.0. Co-existence of different metals inhibited the absorption of metallic ions by mycelial pellets, the more ion species, the more obvious the inhibition. Fig 3, Tab 2, Ref23
