A Gram-negative, motile, aerobic and oval- or rod-shaped bacterial strain, DS-56T, which is phylogenetically closely related to the genus Devosia, was isolated from soil from Dokdo, Korea. Strain DS-56T grew optimally at pH 6.5-7.5 and 25 °C in the presence of 0.5% (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain DS-56T joins the cluster comprising Devosia species, at a bootstrap resampling value of 100%. The levels of 16S rRNA gene sequence similarity between strain DS-56T and the type strains of recognized Devosia species ranged from 95.4 to 96.4%. Strain DS-56T contained Q-11 as the predominant ubiquinone, unlike Devosia species, which contain Q-10 as the predominant ubiquinone. The novel strain also contained some fatty acids, including branched and hydroxy fatty acids, that are not detected in Devosia species. The DNA G+C content of strain DS-56T was 66.2 mol%. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain DS-56T represents a novel species of the genus Devosia, for which the name Devosia insulae sp. nov. is proposed. The type strain is DS-56T (=KCTC 12821T = DSM 17955T).
