title: Structural studies of a novel exopolysaccharide produced by a mutant of Rhizobium meliloti strain Rm1021.
abstract: The structure of a novel expolysaccharide obtained from a mutant of Rhizobium meliloti strain Rm1021 was elucidated by a combination of enzymic, chemical, and spectroscopic methods. The polysaccharide is composed of a disaccharide repeating-unit, beta-D-Glcp-(1----3)-alpha-D-Galp-(1----3), having a 6-O-acetyl group attached to most D-glucose residues and a 4,6-O-(1-carboxyethylidene) group attached to every D-galactose residue.
