A Gram-negative, rod-shaped, Stenotrophomonas-like bacterial strain, DS-16T, was isolated from soil from Dokdo, Korea, and subjected to a polyphasic taxonomic study. Strain DS-16T grew optimally at pH 6.0-7.0 and 30 °C in the presence of 0.5% (w/v) NaCl. It contained Q-8 as the predominant ubiquinone and iso-C16:0, iso-C15:0 and iso-C17:1ω9c as the major fatty acids. The DNA G+C content was 65.1 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DS-16T joined the cluster comprising Stenotrophomonas species. The levels of 16S rRNA gene sequence similarity between strain DS-16T and the type strains of Stenotrophomonas species ranged from 95.5 to 97.5%. DNA-DNA relatedness data and differential phenotypic properties, together with the phylogenetic distinctiveness of strain DS-16T, demonstrated that this novel strain differs from Stenotrophomonas species with validly published names. On the basis of phenotypic, phylogenetic and genetic data, strain DS-16T (=KCTC 12543T=CIP 108839T) should be classified in the genus Stenotrophomonas as a member of a novel species, for which the name Stenotrophomonas dokdonensis sp. nov. is proposed.
