The structure of an exopolysaccharide from Rhizobium sp. strain ANU280 (derivative of the broad host-range strain NGR234) has been determined.Fragments generated by partial acid hydrolysis were fractionated by sequential ion-exchange and gel chromatography, and their structures were assigned by 13C-n.m.r. spectroscopy.Extensive overlap of structure between the fragments, together with the results of periodate oxidation and colorimetric analyses, permitted assignment of the nonasaccharide repeating-unit shown below.The terminal galactosyl group carries a 4,6-O-(1-carboxyethylidene) group and, probably, an acetyl group.
