An irregular rod-shaped, non-gliding, yellow-pigmented bacterium was isolated from seawater from the western North Pacific Ocean near Japan. The strain, designated S1-66T, was Gram-negative, obligately aerobic, heterotrophic and oxidase-positive. Growth occurred in the presence of 1-4 % NaCl, with optimum growth at 2 % NaCl. The strain grew at 15-30 °C, with optimum growth at 20-25 °C. The G+C content of genomic DNA was 48.1 mol% (HPLC). The predominant isoprenoid quinone was MK-6 and the major cellular fatty acids were iso-C15:0 (26.4 %), iso-C15:1 (20.3 %) and iso-C17:0 3-OH (14.2 %). Phylogenetic trees generated by using 16S rRNA gene sequences revealed that strain S1-66T belongs to the family Flavobacteriaceae and showed 94.2 % sequence similarity to the most closely related type strain, Ulvibacter antarcticus IMCC3101T. On the basis of phenotypic and phylogenetic features, S1-66T is classified in a novel genus and species within the family Flavobacteriaceae, for which the name Aureitalea marina gen. nov., sp. nov. is proposed. The type strain of Aureitalea marina is S1-66T (=NBRC 107741T=KCTC 23434T).
从日本附近西太平洋海域的海水中分离到一株不规则杆状、非滑行、黄色素的革兰氏阴性需氧异养氧化细菌。该菌株被命名为 S1-66T,能在 1-4%NaCl 浓度下生长,最适盐度为 2%NaCl。生长温度范围为 15-30°C,最适生长温度为 20-25°C。G+C 含量为 48.1 mol%(HPLC)。主要的异戊二烯醌为 MK-6,主要的细胞脂肪酸为 iso-C15:0(26.4%)、iso-C15:1(20.3%)和 iso-C17:0 3-OH(14.2%)。基于 16S rRNA 基因序列构建的系统发育树显示,菌株 S1-66T 属于黄杆菌科,与最密切相关的模式菌株南极 Ulvibacter antarcticus IMCC3101T 的序列相似性为 94.2%。根据表型和系统发育特征,S1-66T 被分类为黄杆菌科的一个新属和新种,命名为 Aureitalea marina 属,新种。Aureitalea marina 的模式菌株为 S1-66T(=NBRC 107741T=KCTC 23434T)。
