Reclassification of Agromonas oligotrophica into the genus Bradyrhizobium as Bradyrhizobium oligotrophicum comb. nov.
Agromonas oligotrophica JCM 1494(T) was isolated in Japan in 1983, and the name was validly published in 1985. Analysis of the 16S rRNA gene sequence showed that Agromonas oligotrophica LMG 10732(T) ( = JCM 1494(T)) is located within the genus Bradyrhizobium, with Bradyrhizobium denitrificans LMG 8443(T) as its closest relative, showing 99.6 % 16S rRNA gene sequence identity. However, Agromonas oligotrophica LMG 10732(T) and Bradyrhizobium denitrificans LMG 8443(T) can be distinguished by housekeeping gene sequence analysis, phenotypic characterization and DNA-DNA hybridization. Agromonas oligotrophica is also genotypically and phenotypically different from the remaining species of the genus Bradyrhizobium, and we therefore propose the reclassification of Agromonas oligotrophica into the genus Bradyrhizobium as Bradyrhizobium oligotrophicum comb. nov. (type strain LMG 10732(T)  = JCM 1494(T)  = ATCC 43045(T)).
