Techniques Used for Characterization of Microbial Exopolysaccharides

Exopolysaccharides (EPS) that are secreted by the bacteria are one of the main components of its structure. It is usually associated with the cell wall, or the bio film layer of the bacterial cell consisting of a monosaccharide as a framework or network. The study of its properties, structure, functions and interaction will enable us to gain knowledge about the potential benefits of Exopolysaccharides and the role played by them. Many techniques are available to study and analyze the structure. A multidisciplinary approach is needed that will cumulate data and give an insight and in-depth information about Exopolysaccharides. In this chapter, an effort is being made to introduce all the techniques with an emphasis on spectroscopic and microscopic techniques that can be used to characterize the Exopolysaccharides and analyze them. The techniques are described in brief providing subtle information about the principle, technique, advantages and limitations.
