Description of sp. nov., isolated from seawater.

A Gram-stain-negative, non-motile by gliding and moderately halophilic rod-shaped bacterium HN-2-9-2 was isolated from seawater in Tongyeong, Republic of Korea. The strain grew at concentrations of 0.5‒7 % (w/v) NaCl, at pH 5.5‒8.5 and in a temperature range of 18‒45 °C. HN-2-9-2 shared the highest 16S rRNA gene sequence percentage with BH206 (98.2 %). The average nucleotide identity (ANI), average amino acid identity (AAI) and digital DNA-DNA hybridisation (dDDH) values between HN-2-9-2 and the BH206 were 76.0 %, 81.9 % and 19.7 %, respectively. The genome comprised 3 509 958 bp with a DNA G+C content of 43.0%. HN-2-9-2 contained MK-6 as the sole menaquinone. The predominant fatty acids were iso-C, anteiso-C, iso-C 3-OH, iso-C, iso-CG and summed feature 9, comprising iso-Cω6/C 10-methyl. The polar lipids contained phosphatidylethanolamine, one unidentified phospholipid, two unidentified aminolipids, an unidentified glycolipid and six unidentified lipids. The polyphasic taxonomic properties indicate that the strain represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is HN-2-9-2 (=KCTC 82934=NBRC 115920).
