sp. nov., a marine bacterium from deep-sea sediment.

A Gram-stain-negative, rod-shaped and motile strain, designated PAMC 27536, was isolated from deep-sea sediment in the East Sea, Korea. Analysis of the 16S rRNA gene sequence of the strain showed an affiliation with the genus . Phylogenetic analyses revealed that strain PAMC 27536 was related most closely to CL-YJ9 with a 16S rRNA gene sequence similarity of 98.5 % and to other members of the genus (94.0-91.7 %). Genomic relatedness analyses between strain PAMC 27536 and KCCM 42386 gave an average nucleotide identity of 85.6 % and an estimated DNA-DNA hybridization of 24.6 % using the genome-to-genome distance calculator, indicating that they represent genomically distinct species. Cells of strain PAMC 27536 grew optimally at 25-30 °C and pH 7.0-7.5 in the presence of 3 % (w/v) sea salts. The major cellular fatty acids were Cω6 and/or Cω7, Cω6 and/or Cω7, and C. The major isoprenoid quinone was Q-8. The genomic DNA G+C content was 56.1-57.2 mol%. Based on the phylogenetic, chemotaxonomic, genomic and phenotypic data presented, a novel species with the name sp. nov. is proposed, with PAMC 27536 ( = KCCM 43095 = JCM 30410) as the type strain.
