Resumo
Several serological methods have been used for the characterization and identification of soybean bradyrhizobia. However, some problem were non-reactivity of certain strains and cross-reactivity among others. Since lipopolysaccharide (LPS) can often be used in strain identification, the objective was to investigate the antigenic properties and polyacrylamide gel electrophoretic pattern of 12 Brazilian strains of Bradyrhizobium japonicum that nodulate soybean and to compare them to standard strains. The close correlation between the LPS patterns obtained by SDS-PAGE and the serological analysis permitted us to assign the strains to nine groups different or the same as the standard strains.
