sp. nov., of the family , isolated from marine sediment.

A Gram-stain-negative, ovoid or rod-shaped, non-flagellated, motile-by-gliding and aerobic bacteria, designated S10-8, was isolated from marine sediment of the Yellow Sea. Colonies of strain S10-8 had a pink-red pigmentation and its cells were approximately 0.5-0.8 μm×1.0-2.5 μm in size. Growth occurred at 10-45 °C (optimally at 33-37 °C), in the presence of 0-12.0 % NaCl (optimally at 2.0-5.0 %, w/v) and at pH 5.0-8.5 (optimally at pH 7.0-7.5). Phylogenetic analysis of the 16S rRNA gene indicated that strain S10-8 is a member of the genus within the family , and the 16S rRNA gene sequence similarity of strain S10-8 to its closest relative KCTC 12367 was 96.9 %. Strain S10-8 contained MK-7 as the predominant menaquinone and summed feature 4 (iso-C I and/or anteiso-C B) and iso-C as the major fatty acids. The major polar lipids were phosphatidylethanolamine, an unidentified aminophospholipid and an unidentified lipid. The size of the draft genome was 4 623 791 bp and the G+C content was 53.5 mol%. There were low DNA-DNA hybridization values (<48.3±5.2 %) and average nucleotide identity values (<86.5 %) between strain S10-8 and the most closely related recognized species. Therefore, we propose a novel species in the genus to accommodate the novel isolate: sp. nov. (type strain S10-8=KCTC 42769=ACCC 19859).
