Abstract

A Gram-negative, non-motile, non-spore-forming, moderately halophilic rod (strain SM-1) was isolated from salt marsh around the junction of the Youngsan River and the Yellow Sea in Korea and subjected to a polyphasic taxonomic study. This organism grew optimally at 37 °C and was able to grow at 10 and 45 °C. It grew optimally in the presence of 2–3 % (w/v) NaCl. The major fatty acids in strain SM-1 were iso-C and C. Strain SM-1 and DSM 11525 were characterized by having ubiquinone-8 as the predominant respiratory lipoquinone. The DNA G+C content of strain SM-1 was 59 mol%. Phylogenetic analysis based on 16S rDNA sequences showed that strain SM-1 formed a coherent cluster with ; this relationship was supported by a bootstrap resampling value of 100 %. The level of 16S rDNA identity between strain SM-1 and the type strain of was 98·6 %. The mean level of DNA–DNA relatedness between strain SM-1 and the type strain of was 20·6 %. Therefore, on the basis of phenotypic properties, phylogeny and genomic data, strain SM-1 should be placed in the genus as a member of a novel species, for which the name sp. nov. is proposed. The type strain of the novel species is strain SM-1 (=KCCM 41586 =JCM 11542).
