The bacteria from Ochrobactrum genus are commonly found in the soil and association with the roots of plants. The O-polysaccharide and the glucan were isolated from the Ochrobactrum rhizosphaerae PR17(T) strain. Purified polysaccharides were analysed using chemical methods and NMR spectroscopy. Sugar and absolute configuration assignment combined with NMR data revealed the chemical structure of the repeating unit of the O- [formula: see text].
