英文摘要：

The progress in the production of exopolysaccharides by Klebsiella sp.is discussed,including composition,function and fermentation process of the exopolysaccharides.And the problems in the process of exopolysaccharides production are also discussed.It is pointed out that the research emphasis should be placed on using the mathematic tools to optimize the fermentation process and modifying downstream recovery process.Then the comparison with their counterparts and exoploitation of the potential function of the exopolysaccharides will be focused on.
