生物表面活性剂合成的促产因子研究进展

Research Progress in the Impacts of Promoting Factors on Biosurfactants Synthesis

生物表面活性剂是微生物产生的一类具有表面活性的代谢产物,与化学表面活性剂相比,具有高效、低毒、易降解的优点。本文综述了氨基酸、酵母提取物、金属离子和有机酸作为促产因子时,对生物表面活性剂产量、结构和同系物组成影响的研究进展,并对其促产机理进行了归纳总结,最后对此领域的研究进行了展望。

Biosurfactants are a class of surface active metabolites produced by microorganisms. Compared with chemical surfactants,biosurfactants have the advantages of high biodegradability,low toxicity,and high efficiency. Summarizes the research progress in the impacts of promoting factors such as amino acids,yeast extracts,metal ions and organic acids on yield,structure and homologue composition of biosurfactants. In addition,the promoting mechanisms of these factors on biosurfactant production are also concluded. At the end of this review,the prospect on this field are introduced.
