Microbial exopolysaccharides (MPSs) such as xanthan, dextran, gellan or pullulan have been commercially used, in their natural or modified state, for many years. A large number of these natural polymer applications is a consequence of their excellent physical and chemical properties, based on their capacity to alter the basic properties of water (e.g. thickening or gelling). In addition, these polymers have related secondary functions, such as emulsification, suspension, stabilization, encapsulation, flocculation, film forming, binding and coating. MPSs, and particularly exopolysaccharides have many other novel properties to offer, and discovery of immune modulation and bifidogenic effect of some of them should provide other applications. This work focuses on the more recent developments in the extent of application of microbial polysaccharides in the various fields what makes these polymers promising and versatile materials in future, and also on our investigations within these natural products.
