摘　　要：生物表面活性剂是由微生物产生的可降低界面张力的两亲性化合物。因此,生物表面活性剂可以增加溶质溶解度、生物活性以及有机物的分解速率。本研究采用海洋假单胞菌类分析了生物表面活性剂对原油回收和隔离的作用。生物表面活性剂的制备是在玻璃烧瓶内和实验室条件下完成的。本研究试验了两个pH值范围的四种不同浓度的盐溶液,以期获得打破油包水或水包油乳液将油与水隔离开来的最佳生物表面活性剂浓度。当生物表面活性剂浓度为0.1%时可以达到最好的效果。Biological decomposition techniques and isolation of environmental pollutions using biosurfactants bacteria are effective methods of environmental protection. Suffactants are amphiphilic compounds that are produced by local microorganisms and are able to reduce the surface and the stresses between surfaces. As a result, they will increase solubility, biological activity, and environmental decomposition of organic compounds. This study analyzes the effects ofbiosurfactants on crude oil recovery and its isolation using pseudomonas sea bacteria species. Preparation of biosurfactants was done in glass flasks and laboratory conditions. Experiments were carried out to obtain the best concentration ofbiosurfactants for isolating oil from water and destroying oil-inwater or water-in-oil emulsions in two pH ranges and four saline solutions of different concentrations. The most effective results were gained when a concentration of 0.1% biosurfactants was applied.
