A Gram-stain-negative, aerobic, motile by gliding, rod-shaped and pink-coloured bacterium, designated strain SW-16, was isolated from the sediment of small stream in the Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SW-16 formed a lineage within the genus of the family . Phylogenetic analysis also showed that strain SW-16 was most closely related to 15-51 (98.0% 16S rRNA gene sequence similarity), R135 (97.5%), 15-52 (97.4%), DS-27 (97.0%) and THG-T17 (97.0%). Growth was observed at 10-37 °C (optimum at 30 °C), pH 6-8 (optimum at pH 7) and with 0-2.0 % NaCl (optimum at 0%). The major fatty acids of the bacterial strain were iso-C, iso-C 3-OH and summed feature 3 (iso-C 2-OH and/or C 7). The predominant respiratory quinone was menaquinone-7 and the major polar lipids were phosphatidylethanolamine, two unidentified amino lipids, one unidentified phospholipid and three unidentified lipids. The genome size of strain SW-16 was 5.8 Mbp and the G+C content was 38.5 mol%. Based on the results of phenotypic, genomic and phylogenetic analyses, strain SW-16 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is SW-16 (=KEMB 1602-396=KCTC 82079=JCM 34181).
一株革兰氏阴性、需氧、滑行运动、杆状且呈粉红色的细菌，被命名为 SW-16 菌株，从韩国小溪的沉积物中分离得到。基于 16S rRNA 基因序列的系统发育分析表明，SW-16 菌株形成了属内的一个分支。系统发育分析还表明，SW-16 菌株与 15-51（98.0% 16S rRNA 基因序列相似性）、R135（97.5%）、15-52（97.4%）、DS-27（97.0%）和 THG-T17（97.0%）最为密切相关。该菌在 10-37°C（最适温度为 30°C）、pH 6-8（最适 pH 为 7）和 0-2.0% NaCl（最适为 0%）的条件下生长。该菌的主要脂肪酸为 iso-C、iso-C 3-OH 和 sum feature 3（iso-C 2-OH 和/或 C 7）。主要呼吸醌为menaquinone-7，主要极性脂类为磷脂酰乙醇胺、两种未鉴定的氨基酸脂类、一种未鉴定的磷脂和三种未鉴定的脂类。SW-16 菌株的基因组大小为 5.8 Mbp，G+C 含量为 38.5 mol%。基于表型、基因组和系统发育分析的结果，SW-16 菌株代表了属的一个新种，建议将其命名为 sp. nov.。其模式菌株为 SW-16（=KEMB 1602-396=KCTC 82079=JCM 34181）。
