A novel marine bacterium, designated strain CNURIC014(T) was isolated from coastal seawater of Jeju Island in Korea. Strain CNURIC014(T) formed yellow colonies on marine agar 2216 and the cells were Gram-negative, non-motile, strictly aerobic, rod-shaped. The temperature, pH and NaCl ranges for growth were 15-37 degrees C, pH 6.0-9.0 and 1.0-7.0% NaCl. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain CNURIC014(T) was most closely related to Gaetbulibacter marinus and Gaetbulibacter saemankumensis, with a sequence similarity of 95.1% and 94.6%, respectively. The DNA G+C content of the strain was 33.1 mol% and the major respiratory quinone was menaquinone-6. The major cellular fatty acids were iso-C(15:1) (22.8%), iso-C(15:0) (18.8%), summed feature 3 (iso-C(15:0) 2-OH/C(16:1) omega 7c, 12.9%) and iso-C(17:0) 3-OH (11.5%). On the basis of phenotypic, phylogenetic, and genotypic data, strain CNURIC014(T) represents a novel species within the genus Geatbulibacter, for which the name Gaetbulibacter jejuensis sp. nov. is proposed. The type strain is CNURIC014(T)(=KCTC 22615(T) =JCM 15976(T)).
一株新的海洋细菌，命名为 CNURIC014(T) 菌株，从韩国济州岛的沿海海水中分离得到。CNURIC014(T) 菌株在海洋琼脂 2216 上形成黄色菌落，细胞呈革兰氏阴性，非运动性，严格需氧，棒状。生长的温度、pH 值和 NaCl 范围分别为 15-37°C、pH6.0-9.0 和 1.0-7.0%NaCl。基于 16S rRNA 基因序列的系统发育分析表明，菌株 CNURIC014(T) 与 Gaetbulibacter marinus 和 Gaetbulibacter saemankumensis 最为密切相关，序列相似性分别为 95.1%和 94.6%。菌株的 DNA G+C 含量为 33.1mol%，主要呼吸醌为menaquinone-6。主要细胞脂肪酸为 iso-C(15:1)(22.8%)、iso-C(15:0)(18.8%)、summed feature 3(iso-C(15:0)2-OH/C(16:1)omega 7c，12.9%)和 iso-C(17:0)3-OH(11.5%)。基于表型、系统发育和基因型数据，菌株 CNURIC014(T) 代表 Geatbulibacter 属中的一个新种，命名为 Gaetbulibacter jejuensis sp. nov.。模式菌株为 CNURIC014(T)(=KCTC 22615(T)=JCM 15976(T))。
