The Isolation of one Chlorpyrifos Degrading Microbe and the Research of its Degrading Characterisation
A strain of bacteria X1 that can effectively degrade chlorpyrifos is isolated from the activated sludge in the aeration biological tank of municipal sewage treatment plant.X1 is G-.The degradation of chlorpyrifos and the growth are measured by different carbon and nitrogen sources, pH,and temperature.The results show that,the chlorpyrifos is not the single carbon source and nitrogen source to X1,and it has good growth and degradation rates when the pH value is 5.0 and 9.0,the temperature is about 30°C,and the best incubation time is two days,the additional carbon and nitrogen can make X1 grow better,but has little effect on the degradation rate.This study determined the best culture conditions for the bacterial X1 growth and degradation of chlorpyrifos,make theoretical basis for the development of antimicrobial and field application.
