title: Marinobacterium profundumsp. nov., a marine bacterium from deep-sea sediment.
abstract: A Gram-stain-negative, rod-shaped and motile strain, designated PAMC 27536T, 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 genusMarinobacterium. Phylogenetic analyses revealed that strain PAMC 27536Twas related most closely toMarinobacterium rhizophilumCL-YJ9Twith a 16S rRNA gene sequence similarity of 98.5 % and to other members of the genusMarinobacterium(94.0-91.7 %). Genomic relatedness analyses between strain PAMC 27536TandM. rhizophilumKCCM 42386Tgave 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 27536Tgrew 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 C16 : 1ω6cand/or C16 : 1ω7c, C18 : 1ω6cand/or C18 : 1ω7c, and C16 : 0. 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 nameMarinobacterium profundumsp. nov. is proposed, with PAMC 27536T( = KCCM 43095T= JCM 30410T) as the type strain.
