A Gram-staining-negative, oxidase-positive, catalase-positive, non-motile, non-spore-forming, and rod-shaped bacterium, designated BJQ-6(T), was isolated from activated sludge of a waste-water treatment plant in Jiangsu Province, China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain BJQ-6(T) belonged to the genus Rhodanobacter, and shared 98.7% similarity with Rhodanobacter lindaniclasticus LMG 18385(T) and <97% similarities with other Rhodanobacter species. The major fatty acids were iso-C₁₅:₀ (17.6%), iso-C₁₆:₀ (19.3%), and Summed feature 9 (isoC₁₇:₁ ω9c and/or C₁₆:₀ 10-methyl) (25.8%). The DNA G+C content of strain BJQ-6(T) was 64.8 mol%. Based on the phenotypic and phylogenetic considerations, strain BJQ-6(T) represents a novel species of the genus Rhodanobacter, for which the name Rhodanobacter xiangquanii sp. nov. is proposed. The type strain is BJQ-6(T) (=CCTCC AB 2010106(T) =KCTC 23100(T)).
从中国江苏省一家废水处理厂的活性污泥中分离到一株革兰氏阴性、氧化阳性、接触酶阳性、非运动性、非孢子形成、杆状的细菌，命名为 BJQ-6(T)。基于 16S rRNA 基因序列的系统发育分析表明，菌株 BJQ-6(T)属于 Rhodanobacter 属，与 Rhodanobacter lindaniclasticus LMG 18385(T)的相似度为 98.7%，与其他 Rhodanobacter 种的相似度<97%。主要脂肪酸为 iso-C₁₅:₀ (17.6%)、iso-C₁₆:₀ (19.3%)和 Summed feature 9 (isoC₁₇:₁ ω9c 和/或 C₁₆:₀ 10-methyl) (25.8%)。菌株 BJQ-6(T)的 DNA G+C 含量为 64.8mol%。基于表型和系统发育的考虑，菌株 BJQ-6(T)代表了 Rhodanobacter 属的一个新种，现命名为 Xiangquanibacter xiangquanii sp. nov.。模式菌株为 BJQ-6(T)=CCTCC AB 2010106(T)=KCTC 23100(T)。
