A Gram-reaction-negative, aerobic, flagellated and coccoid-shaped bacterial strain, designated SM1702, was isolated from Antarctic intertidal sediment collected off Ardely Island, West Antarctica. The strain grew at 0-30 °C and with 0.5-5.0 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences and single-copy orthologous clusters both showed that strain SM1702, together with , occupied an independent phylogenetic branch, sharing the highest 16S rRNA gene sequence similarity with type strain of the latter (95.6 %). The major fatty acids were summed feature 3 (C 7 and/or C 6), summed feature 8 (C 7 and/or C 6), C, and summed feature 2 (C 3-OH and/or iso-C I). Polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The genomic DNA G+C content of strain SM1702 was 27.1 mol%. Based on the results of the polyphasic characterisation for strain SM1702, it is identified as the representative of a novel species of , for which the name sp. nov. is proposed. The type strain of is SM1702 (=MCCC 1K03471=KCTC 62796).
从南极西部阿德莱岛附近采集的南极潮间带沉积物中分离出一株革兰氏阴性、需氧、具鞭毛且呈球状的细菌菌株，命名为SM1702。该菌株在0-30°C和0.5-5.0%（w/v）NaCl条件下生长。基于16S rRNA基因序列和单拷贝直系同源簇的系统发育分析均表明，菌株SM1702与[此处缺失相关菌名]一起占据一个独立的系统发育分支，与后者的模式菌株具有最高的16S rRNA基因序列相似性（95.6%）。主要脂肪酸为总和特征3（C7和/或C6）、总和特征8（C7和/或C6）、C以及总和特征2（C3-OH和/或异-CI）。极性脂质为磷脂酰乙醇胺和磷脂酰甘油。菌株SM1702的基因组DNA G+C含量为27.1mol%。基于对菌株SM1702的多相特征分析结果，它被鉴定为[此处缺失相关菌属名]一个新物种的代表，为此提出新物种名称[此处缺失新物种名称]sp. nov.。[此处缺失相关菌属名]的模式菌株为SM1702（=MCCC 1K03471=KCTC 62796）。
