title: [Salinicola socius gen. nov., sp. nov., a moderately halophilic bacterium from a naphthalene-utilizing microbial association].
abstract: A chemoorganotrophic, moderately halophilic bacterium (strain SMB35) has been isolated from a naphthalene-utilizing microbial community obtained from salt mines (Perm region of Russia). Strain SMB35 grows in a wide salinity range, 0.5 to 30% (wt/vol) NaCl. Cells are gram-negative rods motile by means of a single polar flagellum. The predominant fatty acids are 16:1omega7, 16:0, 18:1omega7, and 19 cy. The major lipoquinone is an unsaturated ubiquinone with nine isoprene units (Q-9). The DNA G+C content is 63.0 mol%. The 16S rDNA-based phylogenetic analysis has shown that strain SMB35 formed a separate clade in the cluster of the family Halomonadaceae. The 16S rDNA sequence similarity of the isolate to the members of the family is in the range from 90.6% to 95.1%. The phylogenetic and phenotypic differences from Halomonas elongata (the type species of the genus) and from other members of the family suggest that the isolate represents a novel genus and species, for which the name Salinicola socius gen. nov., sp. nov. is proposed. The type strain is SMB35(T) (=VKM B-2397(T)).
