摘　　要：鼠李糖脂是一种阴离子生物表面活性剂,不仅具有表面活性剂增溶、破乳、消泡等特性,还具有低毒、环境友好、易降解等优点。鼠李糖脂是由铜绿假单菌在特定条件下发酵产生,发酵液的分离纯化成为制约其产量及纯度的关键因素。文章对鼠李糖脂发酵液常用的分离纯化方法进行了综述,论述了不同分离方法的优缺点。Rhamolipid is an anionic biosurfactant,which not only has the characteristics of surfactant dissolution,milk breaking and desolization,but also has the advantages of low toxicity,environment friendly and easy degradation.Rhamolipid is produced by the fermentation of P.aeruginosa under specific conditions,and the isolation and purification of fermentation liquid becomes a key factor restricting its yield and purity.This paper reviews the commonly used separation and purification methods of rhamhamhalolipid fermentation broth,and discusses the advantages and disadvantages of different separation methods.
