Bacteria excrete exopolysaccharide around the neighborhood growth. The amount and
composition of the exopolysaccharide is highly variable depending on the genus and species of bacteria. Bacteria
desperately need energy to produce exopolysaccharide. Therefore, the presence of a carbon source in the growth
media can serve as a component in addition to the formation of cells may also serve as a source of energy that is
required for exopolysaccharide synthesis and excretion
