| Abstract: | Lactic acid bacteria（LAB） are generally recognized as safe.Moreover extracellular polysaccharide（EPS） produced by LAB have excellent physical properties and biological activity,which arises people＇s wide concern.Therefore the study of polysaccharide biosynthetic pathways and suger catabolism were very useful to improve the production and structure of EPS.This article provides a review of EPS biosynthetic pathways,genetic regulation,and the research progress of polysaccharide production and structure engineering. |
