abstract= A Gram-stain-negative and facultatively anaerobic bacterium, SY21T, was isolated from marine sediments of the coastal area in Weihai, China (122° 0′ 37″ E 37° 31′ 33″ N). Cells of strain SY21T were 0.3–0.5 μm wide and 1.5–2.5 μm long, catalase- and oxidase-positive. Colonies on 2216E agar were transparent, beige- to pale-brown-pigmented, and approximately 0.5 mm in diameter. Growth occurred optimally at 33–37 °C, pH 7.0–7.5 and in the presence of 2–3 % (w/v) NaCl. Phylogenetic analysis of the 16S rRNA gene indicated that strain SY21T was a member of the genus Mariniphaga within the family Prolixibacteraceae. The closest described neighbour in terms of 16S rRNA gene sequences identity was Mariniphaga anaerophila Fu11-5T (94.7 %). The major respiratory quinone of strain SY21T was MK-7, and the dominant fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and anteiso-C15 : 0. The major polar lipids were phosphatidylethanolamine, aminolipid and an unidentified lipid, and the DNA G+C content was 37.9 mol%. The distinct phylogenetic position and phenotypic traits distinguished the novel isolate from M. anaerophila Fu11-5T. Phenotypic and genotypic analysis indicated that strain SY21T could be assigned to the genus Mariniphaga. The name Mariniphaga sediminis sp. nov. is proposed, with the type strain SY21T ( = KCTC 42260T = MCCC 1H00107T).,
