摘要
乳酸菌(lactic acid bacterial,LAB)的胞外多糖(Exopolysaccharide,EPS)是多种乳酸菌在其生长代谢过程中分泌到细菌细胞壁外的一种次级代谢产物,因安全性高、生物活性好而受到广泛关注和研究。该文结合国内外乳酸菌EPS的研究现状,综述了乳酸菌EPS的生物合成方式、影响因素及功能特性,概述了EPS在食品、医药和环保领域的应用,并探讨乳酸菌EPS现阶段存在的问题以及未来的发展方向,为乳酸菌EPS的进一步开发和多领域应用奠定基础。
Exopolysaccharide(EPS)of lactic acid bacteria(LAB)is the secondary metabolite secreted to the outside of the cell wall by some lactic acid bacteria in the process of growth and metabolism,which has been widely concerned and studied due to its high safety and good biological activity.Combined with the domestic and foreign studies on lactic acid bacteria EPS,this paper reviewed the biosynthesis of lactic acid bacteria EPS,influencing factors and functional characteristics of the research progress.And the application of EPS in the field of food,medicine and environmental protection were briefly summarized.At the same time,the existing problems and future development direction of lactic acid bacteria EPS were discussed,which laid a foundation for the further development and multi-field application of lactic acid bacteria EPS.
