摘　　要：乳酸菌(Lactic acid bacteria,LAB)是一类重要的益生微生物,同时也是一类重要的工业发酵菌,在食品发酵生产上应用广泛,它的代谢产物也受到极大关注。本文总结了乳酸菌代谢合成的胞外多糖(Exopolysaccharide,EPS)的主要生理生化功能以及胞外多糖合成的四个主要过程,以期为乳酸菌EPS的应用、产量提高及结构改造提供指导。Lactic acid bacteria（LAB） were important probiotic microorganisms and critical industry t3actena, which were widely used in fermentation foods. The fermentation productions which produced by LAB were attracted great attention, This paper provided an overview of the main physiological and biochemical functions of exopolysaccharide （EPS） which produced by LAB, Besides, four metabolic pathways which related to exopolysaccharide biosynthesis also had been summarized,in order to provide evidence for the EPS applications, raising yields and structure modification.
