【 摘 要 】

Aiming at the problems of high content and high environmental pollution of phenols in petrochemical wastewater, a strain capable of efficiently degrading phenol, catechol, m-cresol and 2,4-DCP was isolated from petrochemical wastewater and identified as Stenotrophomonas maltophilia, named DSM2. The highest degradation percentages of strain DSM2 to phenol, catechol, m-cresol and 2,4-DCP were 82.65%, 92.28%, 95.39% and 49.28%, respectively. When strain DSM2 was cultured with strain B29 which could produce biosurfactant, the results showed that strain PB29 could promote the degradation to catechol, m-cresol and 2,4-DCP, increased by 4.67%, 30.11% and 17.39%, respectively. And adding biosurfactant produced by strain PB29 enhanced the degradation of phenol and 2,4-DCP, increased by 6.11% and 11.90%.
