An aerobic, Gram-stain-negative, rod-shaped and motile strain, designated SCS-3, was isolated from deep-sea sediment of the South China Sea. Phylogenetic analysis based on the 16S rRNA gene sequence similarities revealed that strain SCS-3 represented a novel species of the genus , with closely related strains '' MSA67 (98.61 %), IFO13584 (98.22 %) and IO390501 (97.72 %). The G+C content of the genomic DNA is 63.44 mol%. The digital DNA-DNA hybridization values with '' MSA67, IFO13584 and IO390501 were 24.50, 21.8 and 24.80 %, respectively. The major polar lipids of strain SCS-3 were diphosphatidylglycerol, phosphatidylglycerol and three unidentified glycolipids. Ubiquinone-10 was the sole isoprenoid quinone, and C, C 7 11-methyl and summed feature 8 (C ω7 and/or C ω6) were the major fatty acids. Based on polyphasic taxonomic data, strain SCS-3 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is SCS-3 (=JCM 34403=GDMCC 1.2221).
一株好氧、革兰氏阴性、杆状、可运动的菌株，被命名为 SCS-3，从南海深海沉积物中分离得到。基于 16S rRNA 基因序列相似性的系统发育分析表明，菌株 SCS-3 代表了一个新的属种，与密切相关的菌株 '' MSA67（98.61%）、IFO13584（98.22%）和 IO390501（97.72%）最为相似。基因组 DNA 的 G+C 含量为 63.44 mol%。与 '' MSA67、IFO13584 和 IO390501 的数字 DNA-DNA 杂交值分别为 24.50、21.8 和 24.80%。菌株 SCS-3 的主要极性脂为双磷脂酰甘油、磷脂酰甘油和三种未鉴定的糖脂。泛醌-10 是唯一的异戊二烯醌，C、C 7 11-甲基和总和特征 8（Cω7 和/或 Cω6）是主要的脂肪酸。基于多相分类学数据，菌株 SCS-3 代表了一个新的属种，建议将其命名为 sp. nov.。模式菌株为 SCS-3（=JCM 34403=GDMCC 1.2221）。
