A strain with high degradability to alkyl-polyoxyethylene （Brij-30）, named B30, was isolated from the sewage of factory. According to bacteria morphology, dying reaction, physiological biochemical reaction and 16S rDNA sequence analysis, this strain was identified as Pan- doraea sp. Furthermore, effects of the bacterium strain （B30） on soil microbial community and Brij-30 degradation were also studied based on house culture. The result showed that nonionic surfactant Brij-30 addition restrained the growth of bacteria and actinomycete in soi...
