Surfactants are chemically synthesized surface-active compounds widely used for large number of applications in various industries. During last few years there is increase demand of biological surface-active compounds or biosurfactants which are produced by large number of microorganisms as they exert biodegradability, low toxicity and widespread application compared to chemical surfactants. They can be used as emulsifiers, de-emulsifiers, wetting agents, spreading agents, foaming agents, functional food ingredients and detergents. Various experiments at laboratory scale on sand-pack columns and field trials have successfully indicated effectiveness of biosurfactants in microbial enhanced oil recovery (MEOR).
表面活性剂是一种化学合成的表面活性化合物，广泛应用于各种工业领域。在过去的几年中，人们对生物表面活性剂或生物表面活性剂的需求不断增加，因为与化学表面活性剂相比，它们具有生物降解性、低毒性和广泛的应用。它们可用作乳化剂、破乳剂、润湿剂、展布剂、发泡剂、功能性食品成分和清洁剂。在沙柱和现场试验中的各种实验室规模实验表明，生物表面活性剂在微生物提高采油率（MEOR）方面的有效性。
