Abstract

To investigate the effects of exogenous bacterial on soil chlorimuron-ethyl pollution remediation, a chlorimuron-ethyl degrading strain LW3 isolated from long-term contaminated soils was used to study the influencing factors of chlorimuron-ethyl reparation in soil microcosms. The results indicated that the rate of degradation was in accordance with the inoculation amount. But when the inoculation amount reached 1.0×106 CFU/g dry soil, then increase the amount of inoculum had no obvious effect on increasing the degradation rate. The optimum degradation temperature was 30℃, the optimum initial pH 7. When soil moisture content was lower than 40%, the degradation rate increased with increasing soil water content. In flooded conditions, the degradation of chlorimuron-ethyl was inhibited seriously.
