Problems such as agricultural safety and environmental pollution by using chlorpyrifos and other pesticides had become major issues which needed to be solved. The white rot fungi had a unique degradation ability and mechanism to a variety of xenobiotic, which had a good prospect in the bioremediation of the environment. Optimizing the conditions of degrading pesticides chlorpyrifos by using phanerochaete chrysosporium were studied in this work. The optimal culture medium and initial pH value were HCHN and 5.5 respectively. The initial concentration of chlorpyrifos added into the culture could be reach 200mg/L with a highest degradation rate at the range of experimental concentration. In addition, veratryl alcohol and Mn²⁺ can effectively promote the degradation. The degradation rate of chlorpyrifos could arrive to 90% in the 15 day under optimal conditions. The present works lay the foundation of study on reducing the residual chlorpyrifos in agricultural and forest products and soil bioremediation in the next step.
