exopolysaccharide
(noun)
 a type of sugar-composed polymer secreted by a microorganism into the external environment
Examples of exopolysaccharide in the following topics:
- 
Glycocalyx- Specifically, this consists mostly of exopolysaccharides, glycoproteins, and glycolipids.
 
- 
Industrial Microorganisms- The bacterial species which are classified under Xanthomonas exhibit the ability to produce the acidic exopolysaccharide commonly marketed as xanthan gum, used as a thickening and stabilizing agent in foods and in cosmetic ingredients to prevent separation.
 
- 
Extremophiles and Biofilms- Interactions among the organisms that populate a biofilm, together with their protective exopolysaccharidic (EPS) environment, make these communities more robust than free-living, or planktonic, prokaryotes.
