abstract= A Gram-stain-negative, rod-shaped, red-pigmented, aerobic bacterium, strain M2T, was isolated from a seawater sample collected from the western Pacific Ocean at a depth of 1000 m and characterized using polyphasic taxonomy. Strain M2T was catalase-positive and oxidase-negative. Cells grew at 4–33 °C (optimum, 25 °C), at pH 6–9 (optimum, 7) and with 0–4 % (w/v) (optimum, 1 %) NaCl. Phylogenetic trees based on 16S rRNA gene sequences showed that strain M2T was associated with the genus Hymenobacter. Strain M2T showed the highest 16S rRNA gene sequence similarities to Hymenobacter actinosclerus CCUG 39621T (95.7 %), Hymenobacter tibetensis XTM003T (95.6 %) and Hymenobacter psychrotolerans Tibet-IIU11T (95.2 %). The DNA G+C content was 59.98 mol%. Strain M2T contained C16 : 1ω5c (25.0 %), iso-C15 : 0 (23.9 %) and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c, 20.4 %) as major cellular fatty acids. The major quinone of strain M2T was menaquinone 7 and the major polar lipid was phosphatidylethanolamine. The major polyamine of strain M2T was sym-homospermidine. The phylogenetic analysis and physiological and biochemical data showed that strain M2T should be classified as representing a novel species of the genus Hymenobacter, for which the name Hymenobacter profundi sp. nov. is proposed. The type strain is M2T (=CCTCC AB 2017185T=KCTC 62120T).,
