Abstract: Mutant strains of Bradyrhizobium japonicum having enhanced nodulation properties were created by transposon mutagenesis of known Bradyrhizobium japonicum strain I-110. The mutant strains grow well in a yeast-extract mannitol medium, produce extracellular polysaccharides at a level greater than the parent strain under appropriate conditions, are capable of growth on a nutirent medium containing a normally inhibitory amount of succinic acid, and contain a 21 Kdalton protein absent from the parent strain. Such strains can be used to inoculate soil in which soybean plants are grown, resulting in improved plant yields.
