A Gram-negative, yellow-coloured, chemoheterotrophic, non-motile, strictly aerobic, rod-shaped bacterium, designated IMCC1914(T), was isolated from coastal surface seawater of the Yellow Sea, Korea. The temperature, pH and NaCl ranges for growth were 3-37 degrees C, pH 8.0-11.0 and 0.5-4.0 %. The DNA G+C content of the strain was 38.1 mol% and the major cellular fatty acids were iso-C(15 : 1) (32.1 %), iso-C(15 : 0) (20.6 %) and iso-C(17 : 0) 3-OH (7.8 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain IMCC1914(T) was related most closely to Gaetbulibacter saemankumensis SMK-12(T), with a sequence similarity of 96.2 %. On the basis of phylogenetic data and several distinct phenotypic characteristics, strain IMCC1914(T) (=KCCM 42380(T) =NBRC 102040(T)) could be assigned to the genus Gaetbulibacter as the type strain of a novel species, for which the name Gaetbulibacter marinus sp. nov. is proposed. In addition, an emended description of the genus Gaetbulibacter is presented.
从韩国黄海沿岸表层海水中分离出一株革兰氏阴性、黄色、化能异养、无运动性、严格需氧的杆状细菌，命名为IMCC1914(T)。该菌株生长的温度范围为3-37℃，pH范围为8.0-11.0，NaCl浓度范围为0.5-4.0%。该菌株的DNA G+C含量为38.1 mol%，主要细胞脂肪酸为异-C(15 : 1)(32.1%)、异-C(15 : 0)(20.6%)和异-C(17 : 0) 3-OH(7.8%)。基于16S rRNA基因序列的系统发育分析表明，菌株IMCC1914(T)与沙门氏菌Gaetbulibacter saemankumensis SMK-12(T)关系最为密切，序列相似性为96.2%。根据系统发育数据和几个明显的表型特征，菌株IMCC1914(T)(=KCCM 42380(T)=NBRC 102040(T))可归为Gaetbulibacter属，作为一个新物种的模式菌株，为此提出新名称Gaetbulibacter marinus sp. nov.。此外，还给出了Gaetbulibacter属的修订描述。
