THE STRUCTURE OF THE EXOPOLYSACCHARIDE OF PSEUDOMONAS FLUORESCENS STRAIN H13

Abstract An acidic exopolysaccharide was isolated from P. fluorescens strain H13. The structure of the polysaccharide repeating unit was determined using chemical methods and 1D and 2D NMR techniques. The repeating unit was characterized as a trisaccharide composed of d -glucose, 2-acetamido-2-deoxy- d -glucose and 4-O- acetyl-2-acetamido-2-deoxy- d -mannuronic acid.
