海藻糖脂的合成及应用前景

Synthesis and applications of trehaloselipids

海藻糖脂是一类生物表面活性化合物,与化学表面活性剂相比,具有低毒、可生物降解、在极端条件下稳定性强、环境友好等优势,具有广泛的应用价值和前景。目前国内还没有大规模商业应用的实例,主要是生产成本高、产量低、产物成分复杂等因素导致。本文中,笔者主要介绍了海藻糖脂的制备方法,分析比较了各种方法的优势与问题,综述了海藻糖脂的性质及其在生物医学、食品、化妆品、生物修复和石油工业领域的应用前景。海藻糖脂由于其特有的性质,将在实际应用中,尤其是在生物医学工程领域方面的应用中有望得到进一步的发展。

Trehalose lipids are glycolipid biosurfactants.In comparison to chemical surfactants,trehalose lipids have the advantages in lower toxicity,higher biodegradability,effectiveness at extremes of temperature,pH and salinity,environment-friendly,they have practical applications and prospects.However,the large-scale commercial success of trehalose lipids is currently scarce.Itis mainly due to the high cost,low yield and complexity of component of production.We introduce hereh the synthesis methods of trehalose lipids,and analyzetheir advantages and problems.We also summarize applications of trehalose lipids in the food,cosmetic,biomedical engineering,environmental protection and oil and petroleum industry.Finally,the advantages of trehalose lipids to other surfactant are highlighted,which enables an efficient development of trehalose lipids in their application,especially in biomedical engineering.
