ABSTRACT
Glucans are d-glucose polymers having unique physical properties and are produced by a wide variety of microorganisms. Glucans are high-molecular-weight (MW) microbial polysaccharides (Manjanna et al. 2009) and can be divided into three groups: exocellular, cell wall, and intercellular. The exocellular polysaccharides (EPS) are easy to isolate from cell culture medium because these are constantly diffused outside the cells. Other types of polysaccharides are integral parts of the cell wall or capsular products, and therefore difcult to separate from cell biomass.
