报告了从油田分离到的XL—02菌株对石油烃的降解,探讨了pH值、接种量、油质量浓度及温度对菌体生长和降油率的影响。结果表明,XI-02菌株对pH值具有较宽的适应范围,且pH值在7.0～7.5时,降油效果最好;随着接种量的增加除油率逐步增加;相对较低的含油量和在30～35℃下除油率高。
The degradation of petroleum hydrocarbons by XL-02 strain isolated from the oilfield was reported. The effects of pH value, inoculum size, oil mass concentration and temperature on the growth and oil drop rate of the cells were also discussed. The results showed that strain XI-02 had a wide range of pH value, and the best oil-reducing effect was obtained at pH 7.0-7.5. With the inoculation amount increasing, the oil removal rate gradually increased. The relatively low oil content And high oil removal rate at 30-35 ° C.
