摘　　要：采用铜绿假单胞菌AB91095自制鼠李糖脂发酵液,并将其运用到含油废水的微生物处理中,考察其对戈登氏菌降解石油烃的影响.实验结果表明,采用浓度为12 CMC的鼠李糖脂发酵液,在添加量分别为3 mL、5 mL、7 mL条件下,戈登氏菌对石油烃的降解率相应提高了11.97%、16.11%、18.88%.可见,鼠李糖脂发酵液可以明显促进戈登氏菌对石油烃的降解作用.实验过程同时发现鼠李糖脂发酵液本身对石油烃无降解作用.Rhamnolipid fermentation broth produced by P. aeruginosa AB91095 was used for oily wastewater treatment. The effect of oil degradation by Gordon＇s bacteria was studied with rhamnolipid fermentation broth. The results showed that the oil cannot be degraded by rhamnolipid fermentation broth, while it can enhance the degradation of oil with Gordon. The degradation rate increased 11.97%, 16. 11% and 18.88% respectively by adding 3 mL, 5 mL and 7 mL rhamnolipid broth, and the experimental results showed rhamnolipid fermentation alone can not enhance the degradation of oil.
