Polysaccharides are essential natural metabolites found in all life forms such as microorganisms, animals and plants with various biochemical structures and biological functions. Among all the life forms microbial exopolysaccharides are produced in shorter time duration as they responsible for the microbial cell adhesion and protection during unfavorable growth conditions. Microbial exopolysaccharides are composed of repeated sugar units of same or different types and form a complex by associating with proteins, lipids, metal ions, extracellular DNA (eDNA), organic and inorganic compounds to form a protective layer around the microbial colonies collectively known as biofilm. Specific functions of exopolysaccharides depend on structural composition and habitat of a host microorganism. There are various techniques to study the composition and structure of exopolysaccharides such as High Performance Anion Exchange Chromatography with Pulsed Amperometric Detection, Size Exclusion Chromatography coupled with multi-laser light scattering (SEC-MALLS),X-Ray diffraction (XRD), Differential Scanning Calorimetry (DSC), Fourier Transform Infrared (FTIR) and Thermal Gravimetric Analysis (TGA), etc. In the current article, we reviewed microbial exopolysaccharides physiochemical properties, composition, analyzing techniques through which possible commercial applications in dairy products, cosmetics, research, agriculture and petroleum industry can be performed.

微生物胞外多糖：合成途径，类型及其商业应用。
多糖是存在于所有生命形式中的必不可少的天然代谢产物，例如具有各种生化结构和生物学功能的微生物，动植物。在所有生命形式中，微生物胞外多糖的产生时间较短，因为它们在不利的生长条件下负责微生物细胞的粘附和保护。微生物胞外多糖由相同或不同类型的重复糖单元组成，并通过与蛋白质，脂质，金属离子，细胞外DNA（eDNA），有机和无机化合物缔合而形成复合物，从而在微生物菌落周围形成保护层，统称为生物膜。胞外多糖的具体功能取决于宿主微生物的结构组成和栖息地。
