摘要： A Gram-stain-negative, rod-shaped, red-pigmented, aerobic bacterium, strain M2(T), was isolated from a seawater sample collected from the western Pacific Ocean at a depth of 1000 m and characterized using polyphasic taxonomy. Strain M2(T) was catalase-positive and oxidase-negative. Cells grew at 4-33 degrees C (optimum, 25 degrees 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 M2(T) was associated with the genus Hymenobacter. Strain M2(T) showed the highest 16S rRNA gene sequence similarities to Hymenobacter actinosclerus CCUG 39621(T) (95.7 %), Hymenobacter tibetensis XTM003(T) (95.6 %) and Hymenobacter psychrotolerans Tibet-IIU11(T) (95.2 %). The DNA G+C content was 59.98 mol%. Strain M2(T) contained C-16 (:) (1)omega 5c (25.0 %), iso-C-15 (:) (0) (23.9 %) and summed feature 3 (C-16 (: 1)omega 6c and/or C-16 (:) (1)omega 7c, 20.4 %) as major cellular fatty acids. The major quinone of strain M2(T) was menaquinone 7 and the major polar lipid was phosphatidylethanolamine. The major polyamine of strain M2(T) was sym-homospermidine. The phylogenetic analysis and physiological and biochemical data showed that strain M2(T) 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 M2(T)(=CCTCC AB 2017185(T)=KCTC 62120(T)).
