%X This study investigated the effect of Cd on remediation of DDT contaminated soil using free laccase and immobilized reversed micelles laccase. The results show: degradation rates of ingredients of DDT and total DDT reduced with increasing of Cd concentration, the higher percentage of components in total DDT, the greater impact of Cd on them. Degradation rates of different components were p, p'-DDT > p, p'-DDD > o,p'-DDT > p, p'-DDE. When Cd concentration was 0, 0.5, 1 and 2 mg x kg(-1), the responding degradation rates of DDTs were measured at 50.68%, 32.50%, 14.92% and 13.40%, respectively. Compared with free laccase, degradation rate of total DDT by immobilized reversed micelles laccase nearly increased by 20% in soil without Cd and 30% in soil with 0.5 mg x kg(-1) Cd, implying that immobilized reversed micelles laccase is more effective for DDT degradation than free laccase.
