Devosia insulae sp. nov., isolated from soil, and emended description of the genus Devosia.
A Gram-negative, motile, aerobic and oval- or rod-shaped bacterial strain, DS-56(T), which is phylogenetically closely related to the genus Devosia, was isolated from soil from Dokdo, Korea. Strain DS-56(T) grew optimally at pH 6.5-7.5 and 25 degrees 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-56(T) joins the cluster comprising Devosia species, at a bootstrap resampling value of 100 %. The levels of 16S rRNA gene sequence similarity between strain DS-56(T) and the type strains of recognized Devosia species ranged from 95.4 to 96.4 %. Strain DS-56(T) 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-56(T) was 66.2 mol%. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain DS-56(T) represents a novel species of the genus Devosia, for which the name Devosia insulae sp. nov. is proposed. The type strain is DS-56(T) (=KCTC 12821(T)=DSM 17955(T)).
