ABSTRACT
A gram-negative, motile, non-spore-forming rod, designated NS12(T), was isolated from macerated petioles of Rumex sp. after enrichment with oxalate. On the basis of 16S rRNA gene sequence similarity, strain NS12(T) was phylogenetically related to the genera Azorhizobium and Xanthobacter in the class Alphaproteobacteria. Strain NS12(T) was most closely related to Azorhizobium doebereinerae BR 5401(T) and Azorhizobium caulinodans ORS 571(T) (98.3 and 97.3â% 16S rRNA gene sequence similarity, respectively). Membership of the genus Xanthobacter was excluded by phenotypic characterization. The whole-cell fatty acid compositions of the isolate was typical of members of the genus Azorhizobium with C18ââ1ω7c, cyclo-C19ââ0ω8c, 11-methyl-C18ââ1ω7c and C16ââ0 as the main components. The results of DNA-DNA hybridization and physiological tests allowed the genotypic and phenotypic differentiation of strain NS12(T) from the two members of the genus Azorhizobium. Therefore it is concluded that the isolate represents a novel species of the genus Azorhizobium, for which the name Azorhizobium oxalatiphilum sp. nov. is proposed. The type strain is NS12(T) (â=âDSM 18749(T)â=âCCM 7897(T)). The description of the genus Azorhizobium is also emended.
