摘要：
A PNP -degrading strain was isolated from parathion-methyl contaminated soil sample and identified as Arthrobacter on the basis of its complete 16S rRNA gene sequence analysis. The strain could tolerate concentrations of PNP up to 300 mg/L and degrading completely 200 mg/L PNP within 16 h. To study the applicability of the strain for bioremediation of PNP, The effects of parameters such as pH value ,salinities, glucose concentrations on PNP degradation were investigated.The experimental results showed that biodegradation of PNP occurred quickly at an optimal pH of 8.0 and at 0.1% salt (NaCl) contents and 0.01%(W/V) glucose were the best cosubstrate for the process of PNP biodegradation.
