A Gram-stain-negative, aerobic, chemoheterotrophic, yellow, non-motile and flexirubin-positive bacterium, designated strain IMCC12008(T), was isolated from coastal seawater of the Yellow Sea and subjected to polyphasic taxonomy. Optimal growth was observed at 25 °C, pH 7.0 and in the presence of 2% (w/v) NaCl. Based on 16S rRNA gene sequence analysis and subsequent phylogenetic analyses, strain IMCC12008(T) belonged to the genus Ulvibacter of the family Flavobacteriaceae, with Ulvibacter antarcticus IMCC3101(T) (96.0%) and Ulvibacter litoralis KMM 3912(T) (95.8%) having the highest sequence similaries. The major fatty acids were iso-C(15 : 0) (26.2%) and iso-C(15 : 1) G (10.5%). The DNA G+C content was 38.1 mol%. Strain IMCC12008(T) contained menaquinone-6 (MK-6) as the respiratory quinone, and polar lipids comprising phosphatidylethanolamine, two unidentified aminolipids and an unknown aminophospholipid. On the basis of data collected from this study, strain IMCC12008(T) ( = NBRC 109484(T) = KCTC 32322(T)) represents a novel species of the genus Ulvibacter, for which the name Ulvibacter marinus sp. nov. is proposed.
一株革兰氏阴性、需氧、化能异养、黄色、非运动和富含菲啶的细菌，被命名为菌株 IMCC12008(T)，从黄海沿海水域中分离得到，并进行了多相分类学研究。最佳生长条件为 25°C、pH7.0 和 2%（w/v）NaCl。基于 16S rRNA 基因序列分析和后续的系统发育分析，菌株 IMCC12008(T)属于黄杆菌科的 Ulvibacter 属，与 Ulvibacter antarcticus IMCC3101(T)（96.0%）和 Ulvibacter litoralis KMM 3912(T)（95.8%）具有最高的序列相似性。主要脂肪酸为 iso-C(15 : 0)（26.2%）和 iso-C(15 : 1) G（10.5%）。DNA G+C 含量为 38.1mol%。菌株 IMCC12008(T)含有menaquinone-6 (MK-6)作为呼吸醌，极性脂类包括磷脂酰乙醇胺、两种未鉴定的胺脂和一种未知的胺磷脂。基于本研究收集的数据，菌株 IMCC12008(T)（ = NBRC 109484(T) = KCTC 32322(T)）代表了 Ulvibacter 属的一个新种，命名为 U. marinus sp. nov.。
