title: Stenotrophomonas dokdonensis sp. nov., isolated from soil.
abstract: A Gram-negative, rod-shaped, Stenotrophomonas-like bacterial strain, DS-16(T), was isolated from soil from Dokdo, Korea, and subjected to a polyphasic taxonomic study. Strain DS-16(T) grew optimally at pH 6.0-7.0 and 30 degrees C in the presence of 0.5 % (w/v) NaCl. It contained Q-8 as the predominant ubiquinone and iso-C(16 : 0), iso-C(15 : 0) and iso-C(17 : 1)omega9c 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-16(T) joined the cluster comprising Stenotrophomonas species. The levels of 16S rRNA gene sequence similarity between strain DS-16(T) 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-16(T), demonstrated that this novel strain differs from Stenotrophomonas species with validly published names. On the basis of phenotypic, phylogenetic and genetic data, strain DS-16(T) (=KCTC 12543(T) = CIP 108839(T)) should be classified in the genus Stenotrophomonas as a member of a novel species, for which the name Stenotrophomonas dokdonensis sp. nov. is proposed.
