| 摘 要： | 从胜利油田采出水及其它样品中筛选得到破乳效果较好的D3破乳菌,考察了该破乳菌的培养条件及代谢产物。结果表明,D3菌的适宜生长条件为:温度40℃,pH 7~9,培养时间72 h。D3菌为革兰氏阴性细菌,归为沙雷氏菌属;其代谢产物主要含有:鼠李糖酯、脂肽类、醛、胺。D3菌质量浓度10 g/L时,油水的界面张力由7.65 mN/m降至0.98 mN/m;当菌浓度在0.5~1.0 g/L时,含油污水的除油率大于50%。 |

| Abstract: | D3 biodemusifier was obtained from oil water of Shengli oil field and other oil fields.The better growth condition of D3 biodemusifier is 40 ℃,pH 7~9 and training time 72 h.D3 biodemusifier is Grain-negative bacteria,and it belongs to Serratia.Its metabolite mainly contain rhamnolipid,lipopeptide,aldehyde and amine.When the mass concentration of D3 is 10 g/ L,the interfacial tension is reduced from 7.65 mN/m to 0.98 mN/m.When the mass concentration of D3 is 0.5～1.0 g/L,the rate of removing oil is over 50% from oil wastewater. |
