摘　　要：Ｐｓｅｕｄｏｍｏｎａｓ ２３—１菌株烃代谢产生一种胞外糖脂类表面活性剂。分析表明，糖脂的糖基为鼠李糖，脂肪酸是十碳癸酸。发酵液糖脂含量１１．５ｇ／Ｌ，其临界胶束浓度（ＣＭＣ）为２００ｍｇ／Ｌ，乳化性能稳定。产生糖脂类生物表面活性可能是该菌株微生物采油增油效果显著的主要原因。Pseudomonas 23-1 Can metabolize hydrocarbon to produce the surfactant which is glycolipid outside the cell. The glycolipid, whose content is 1.25g / L, is composed of rhamnose and tencarbon fatry acid. It's critical micella concentration is 200g/L. It has the good ability to emulsify the oil. The main reason of improving the product of oil, decreasing the viscosity and enhancing the flow of oil is the effect of surfastant-glycolipid.
