Abstract: The majority of bacteria are packaged by extracellular polysaccharides,which play an important role in their survival and growth,whether in nature or pathological conditions.The unique bioactivities of bacterial expolysaccharides and their application prospects were paid great attention by the concerned people.The structure,physical and chemical characteristics,biological activities of polysaccharides produced by bacterium were introduced in detail in this paper,especially the application of several bacterial expolysaccharides in industry.The future development of bacteria polysaccharides was envisaged.It provides theoretical basis for the further development of functional bacteria and expansion of application of bacterial exopolysaccharides in industrial.

Key words: Bacterial expolysaccharides, Bioactivities, Application
