从渤海表层沉积物中分离到一株革兰氏染色阴性杆状兼性好氧菌株，由单色（极或侧）鞭毛运动，命名为BSS09T。在10-45°C（最适32°C）、1.0 - 7.0% (w/v) NaCl（最适4.0%）和5.0-8.0（最适pH 6.0）条件下观察生长。基于16S rRNA基因序列的系统发育分析表明，菌株bss09t属于roseibiumu属，与oseibium hamelinenseJCM 10544T序列相似性最高，为96.5%。显著优势脂肪酸为C18: 1ω7c。极性脂质包括一种磷脂酰胆碱、一种磷脂酰单甲基乙醇胺、一种未知的氨基脂、一种磷脂酰甘油、一种磷脂酰乙醇胺和一种未知的极性脂质。主要呼吸醌为Q-10。菌株bss09tdna G+C含量为57.1%。根据这一多相研究的证据，菌株BSS09Tis被认为是roseibium属的一个新种，其名称为ameroseibium sediminissp。11月被提议。型应变为BSS09T（=KCTC 52373T=MCCC 1K03201T）。
A Gram-stain-negative, rod-shaped, facultatively aerobic strain, motile by a monotrichous (polar or lateral) flagellum, designated BSS09T, was isolated from surface sediment of the Bohai Sea, PR China. Growth was observed at 10–45 °C (optimum 32 °C), in the presence of 1.0–7.0 % (w/v) NaCl (optimum 4.0 %) and at pH 5.0–8.0 (optimum pH 6.0). Phylogenetic analysis, based on 16S rRNA gene sequences, revealed that strain BSS09Tbelonged to the genusRoseibiumand showed the highest sequence similarity of 96.5 % toRoseibium hamelinenseJCM 10544T. The significant dominant fatty acid was C18 : 1ω7c. The polar lipids comprised one phosphatidylcholine, one phosphatidylmonomethylethanolamine, one unidentified aminolipid, one phosphatidylglycerol, one phosphatidylethanolamine and one unidentified polar lipid. The major respiratory quinone was Q-10. The DNA G+C content of strain BSS09Twas 57.1 mol%. On the basis of evidence from this polyphasic study, strain BSS09Tis proposed to represent a novel species of the genusRoseibium, for which the nameRoseibium sediminissp. nov. is proposed. The type strain is BSS09T(=KCTC 52373T=MCCC 1K03201T).
