abstract= A facultatively anaerobic, Gram-stain-negative, non-motile and straight to slightly curved long rod-shaped bacterial strain, designated XSD2T, was isolated from coastal seawater of Xiaoshi Island, PR China. The cells were catalase-positive, oxidase-negative and non-flagellated. Strain XSD2T was found to grow at 20–40 °C (optimum, 33 °C), at pH 6.0–8.5 (pH 7.0–7.5) and with 1–5 % (w/v) NaCl (3 %). Carotenoid pigments were produced. The major cellular fatty acids (>10.0 %) were iso-C15 : 0, iso-C16 : 0 3-OH and C17 : 1ω6c and the major polar lipids were phosphatidylethanolamine, one unidentified aminolipid and three unidentified polar lipids. The sole respiratory quinone was MK-7 and the genomic DNA G+C content was 44.1 mol%. The result of the 16S rRNA gene sequence analysis confirmed the affiliation of this organism to the order Marinilabiliales , family Prolixibacteraceae , with Mariniphaga sediminis SY21T as its closest relative with only 93.6 % sequence similarity. On the basis of physiological, biochemical and chemotaxonomic characteristics, we propose that strain XSD2T (=KCTC 62994T=MCCC 1H00347T) represents a novel species of a novel genus in the family Prolixibacteraceae , for which the name Maribellus luteus gen. nov., sp. nov. is proposed.,
