Root-nodule bacteria were isolated from Inga laurina (Sw.) Willd. growing in the Cerrado Amazon
region, State of Roraima, Brazil. The 16S rRNA gene sequences of six strains (BR 10250 T
, BR
10248, BR 10249, BR 10251, BR 10252 and BR 10253) showed low similarities with currently
described species of the genus Bradyrhizobium. Phylogenetic analyses of sequences of five
housekeeping genes (dnaK, glnII, gyrB, recA and rpoB) revealed Bradyrhizobium iriomotense
EK05 T to be the closest type strain (97.4 % sequence similarity or less). Chemotaxonomic data,
including fatty acid profiles [with the major components C16 : 0 and summed feature 8 (C18 : 1v6c/
C18 : 1v7c)], the slow growth rate and carbon compound utilization patterns supported the
assignment of our strains to the genus Bradyrhizobium. Results from DNA–DNA hybridizations and
physiological traits differentiated our strains from the closest related species of the genus
Bradyrhizobium with validly published names. Sequences of symbiosis-related genes for
nodulation (nodC) and nitrogen fixation (nifH) grouped together with those of B. iriomotense
EK05T and Bradyrhizobium sp. strains BR 6610 (used as a commercial inoculant for Inga
marginata in Brazil) and TUXTLAS-10 (previously observed in Central America). Based on these
data, the six strains represent a novel species, for which the name Bradyrhizobium ingae sp. nov. is
proposed. The type strain is BR 10250T (5HAMBI 3600 T
)
