Abstract:

In order to provide the theoretic basis in bioremediation, the cypermethrin degradation microbial community CD-1 was obtained from cypermethrin contaminated oil. The degradation characteristics and the optimal degraing conditions were studied. The result shows that CD-1 has wide range adaptability to environmental. When the initial concentration of cypermethrin was lower than 250 mg/L, the degrading efficiency could reach more than 90% after 72 hours at pH 7.5 and 30℃. Under natural conditions, the degrading efficency of CD-1 was up to 80% after 5 days.
