ABSTRACT
A Gram-stain-negative, facultatively anaerobic, non-motile, rod-shaped and orange-pigmented bacterium, designated 1505T, was isolated from marine sediment that was obtained off the coast of Weihai, PR China. Strain 1505T was found to grow at 10-35 °C (optimum, 28 °C), at pH 6.0-9.0 (optimum, 7.5) and in the presence of 1-4â% (w/v) NaCl (optimum, 2â%). Cells were positive for oxidase and catalase activity. The 16S rRNA gene based phylogenetic analysis revealed that the nearest phylogenetic neighbours of strain 1505T were Seonamhaeicola algicola Gy8T (97.1â%), Seonamhaeicola marinus B011T (96.3â%) and Seonamhaeicola aphaedonensis KCTC 32578T (95.6â%). Based on phylogenomic analysis, the average nucleotide identity values between strain 1505T and S. algicola Gy8T, S. marinus B011T and S. aphaedonensis KCTC 32578T were 75.9, 76.0 and 77.7â%, respectively; the digital DNA-DNA hybridization values based on the draft genomes between strain 1505T and S. algicola Gy8T, S. marinus B011T and S. aphaedonensis KCTC 32578T were 20.0, 20.7 and 21.4â%, respectively. Menaquinone-6 (MK-6) was detected as the major respiratory quinone. The dominant cellular fatty acids were iso-C15ââ1 G and C18ââ1ω9c. The DNA G+C content of strain 1505T was 33.3 mol%. The polar lipids included phosphatidylethanolamine, six aminolipids and four unidentified lipids. Based on its phylogenetic and phenotypic characteristics, strain 1505T is considered to represent a novel species of the genus Seonamhaeicola, for which the name Seonamhaeicola maritimus sp. nov. is proposed. The type strain is 1505T (=KCTC 72528T=MCCC 1H00389T).
