ABSTRACT
This study reports structural information on extracellular, water-soluble polysaccharides from 5 different strains of Rhizobium, viz. R. trifolii J60, R. meliloti J1017, 202, 204 and 207. All the 5 polysaccharides had glucose and galactose in approximate molar ratio of 71. Methylation analysis revealed that the polysaccharides contained (1 leads to 3), (1 leads to 6), (1 leads to 4), (1 leads to 4, 1 leads to 6)-linked D-glucose residues, (1 leads to 3)-linked D-galactose and non-reducing terminal D-glucose attached to pyruvate. This structure was found to be exactly the same as that of succinoglycan, a succinic acid containing water-soluble polysaccharide elaborated by Alcaligenes faecalis var. myxogenes 10C3. The similarity of the structure of polysaccharides of two different Rhizobium species and also to the polysaccharide produced by Alcaligenes are discussed in terms of host specificity.
