Biological functions of Aclnetobacter sp. exopolysaccharides

T. P. Pirog

Acinetobacter sp. exopolysaccharide (EPS) shows protective func¬tions as regards producer cells and protects from unfavourable environmental factors microorganisms cells which are in trophic relationship with Acinetobacter sp. Definite microorganisms (micro-mycetes, anaerobic sulpliate- and chromate-reducing bacteria, some of the aerobic heterotrophs) use EPS as a sole carbon source. EPS synthesized by Acinetobacter sp. can be a source of nonorganic cations for microorganisms under the conditions of low concen¬trations of nutrients.
