摘　　要：The widespread use of pesticides has caused serious harm to ecosystems,necessitating effective and environmentally friendly treatment methods.Bioremediation stands out as a promising approach for pollutant treatment,wherein the metabolic activities of microorganisms can transform toxic pesticides into compounds with lower or no toxicity.In this study,we obtained eight pesticide-degrading strains from pesticide-contaminated sites through continuous enrichment and screening.Four highly efficient pesticide-degrading strains(degradation ratios exceeding 80%)were identified.Among them,Pseudomonas sp.BL5 exhibited the strongest growth(exceeding 10^(9) CFU·ml^(-1))and outstanding degradation of benzene derivatives and chlorinated hydrocarbons at both laboratory and pilot scales,with degradation ratios exceeding 98%and 99.6%,respectively.This research provides new tools and insights for the bioremediation of pesticide-related pollutants.
