A Gram-reaction-negative, non-motile, strictly aerobic, dark pink-pigmented and rod-shaped bacterial isolate, designated 14-121-B13T, was isolated from surface seawater off the coast of the South Sea at Namhae-gun, Republic of Korea. Cells were catalase- and oxidase-positive and required NaCl for growth. Strain 14-121-B13T grew optimally at 30 °C, in the presence of 2 % (w/v) NaCl and at pH 7.5-8.0.Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain 14-121-B13T clustered with the type strain of Umboniibacter marinipuniceus, with which it exhibited 96.7 % sequence similarity. The DNA G+C content of strain 14-121-B13T was 48.9 mol%. The major cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0. The major respiratory quinone was ubiquinone Q-7 and the polar lipids detected in strain 14-121-B13T were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unidentified aminolipid, unidentified phospholipids, unidentified aminophospholipids and unidentified lipids. Based on the phenotypic, chemotaxonomic and phylogenetic data presented, strain 14-121-B13T is considered to represent a novel species of the genus, Umboniibacter for which the name Umboniibacter roseus sp. nov. is proposed. The type strain is 14-121-B13T ( = DSM 29882T = KCTC 42467T).
从韩国南海郡南海海岸的表层海水中分离出一株革兰氏阴性、无运动性、严格需氧、深粉色色素沉着的杆状细菌,命名为14-121-B13T。细胞过氧化氢酶和氧化酶呈阳性,生长需要氯化钠。菌株14-121-B13T在30 °C、2%(w/v)氯化钠存在及pH 7.5 - 8.0条件下生长最佳。基于16S rRNA基因序列构建的邻接法、最大似然法和最大简约法系统发育树表明,菌株14-121-B13T与海紫红脐菌模式菌株聚类在一起,与其序列相似性为96.7%。菌株14-121-B13T的DNA G+C含量为48.9 mol%。主要细胞脂肪酸为特征性总和3(C16 : 1ω7c和/或C16 : 1ω6c)和C16 : 0。主要呼吸醌为泛醌Q-7,在菌株14-121-B13T中检测到的极性脂类有双磷脂酰甘油、磷脂酰甘油、磷脂酰乙醇胺、一种未鉴定氨基脂、未鉴定磷脂、未鉴定氨基磷脂和未鉴定脂类。根据所提供的表型、化学分类和系统发育数据,菌株14-121-B13T被认为代表脐菌属的一个新物种,为此提出玫瑰色脐菌新种(Umboniibacter roseus sp. nov.)。模式菌株为14-121-B13T( = DSM 29882T = KCTC 42467T)。
