CHEMICAL-COMPOSITION OF EXOPOLYSACCHARIDES PRODUCED BY ACINETOBACTER SP ON MEDIA WITH VARIOUS K+ CONCENTRATIONS

Exopolysaccharides produced by Acinetobacter sp. grown on media with v arious contents of K+ had the same molar proportion of neutral monosac charides (rhamnose, mannose, galactose, and glucose) as well as of glu curonic and pyruvic acids. At the same time, they differed in their mo lar proportion of acylated and nonacylated polysaccharides and the con tent of fatty acids in their acylated polysaccharides. The properties of the exopolysaccharide solutions of Acinerobacter sp. are determined by the relative contents of acylated and nonacylated polysaccharides and the content of fatty acids in acylated polysaccharides.
