Abstract: With the development of glycobiology, the unique physical and chemical characteristics and bioactivities of bacterial expolysaccharides were paid great attentions by the concerned people. The classification and structure, physical and chemical characteristics,b iologicala ctivities andr elationship ofs tructurea ndf unctiono fp olysaccharidesp roducedb yb acteriumw ere introduced in detail in this paper. And the prospect of bacteria polysaccharides was envisaged. These information could be used as a theoretical foundation for the study and development of novel polysaccharides.

Key words: bacteriale xopolysaccharides, structure-function relation, characteristics, application
