Exopolysaccharide (EPS) production has been reported in both prokaryotes
and eukaryotes. Bacterial EPSs have been used in both food and non-food applications.
The demand for these EPSs has increased in the last two decades due to various
advantages associated with these biopolymers compared to other plant and animal
based hydrocolloids. Synthesis mechanism, structure, and characteristics of EPS vary
with species of bacteria. Different methods of isolation and characterization of bacterial
EPS have been reported. EPSs of bacteria have various technological properties, which
suit their application in various industries. This chapter discusses the classification of
EPS, EPS-producing bacterial species, biosynthesis of homopolysaccharides and
heteropolysaccharides, extraction and purification of EPS, characterization of EPS,
functional properties and various food applications of EPSs, and health benefits of
EPSs.
