Proposal for combining Bradyrhizobium spp. (Aeschynomene indica) with Blastobacter denitrificans and to transfer Blastobacter denitrificans (Hirsch and Muller, 1985) to the genus Bradyrhizobium as Bradyrhizobium denitrificans (comb. nov.).

The symbiotic bradyrhizobia of Aeschynomene indica and the aquatic budding bacterium Blastobacter denitrificans have much in common and this study broadens the characters that are shared between the two. The 23S rRNA gene sequences of the bradyrhizobial isolates were most similar to each other and to the sequence of Bl. denitrificans.
