	<span style="line-height:1.5;">The removal of pesticides in the environment mainly
depends on natural degradation, especially on microbial degradation.
Biodegradation has many advantages, such as
complete degradation, no secondary pollution, quick effect and wide spectrum.
Based on the single-factor experiments and Box-Benhnken design, the effect of four factors on the degradation of
chlorpyrifos by </span><i style="line-height:1.5;">P. stutzeri </i><span style="line-height:1.5;">ZH-1 was investigated. The four factors,
including temperature (¡æ), oscillator speed
(rpm), inoculum concentration (%) and pH, and their interactions on the
degradation of chlorpyrifos were studied through the use of respons</span><span style="line-height:1.5;">e surface
analysis. The optimal conditions of chlorpyrifos-degrading were
as follows: Temperature 36.7¡æ, oscillator speed 130.00 rpm, inoculum concentration 7%, pH 7. Under these
conditions, the
degradation rate of chlorpyrifos was 96.48%. Moreover, </span><i style="line-height:1.5;">P.</i><i style="line-height:1.5;"> stutzeri </i><span style="line-height:1.5;">ZH-1 could be used efficiently for remediation of contaminated
soils.</span>
