O-specific polysaccharide was obtained by mild acid hydrolysis of the lipopolysaccharide of plant-growth-promoting rhizobacteria Azospirillum doebereinerae GSF71 and studied by sugar analysis along with H and C NMR spectroscopy, including 2D H,H COSY, TOCSY, ROESY, H,C HSQC, and HMBC experiments. It was established that the polysaccharide is linear and consists of tetrasaccharide repeating units with the following structure.
