Extracellular polysaccharide composition, ex planta nitrogenase activity, and DNA homology in Rhizobium japonicum



Extracellular polysaccharide composition, ex planta nitrogenase activity, and DNA homology in Rhizobium japonicum



Journal of Bacteriology 158(3): 1168-1171



The composition of the major acidic extracellular polysaccharide (EPS) of 25 strains of Rhizobium japonicum was determined. Eight strains synthesized an acidic EPS containing rhamnose and 4-O-methylglucuronic acid and were closely related according to DNA homology; these strains also expressed high levels of ex planta nitrogenase activity.
