A Gram-stain-negative, facultative anaerobic, non-motile, rod-shaped strain was isolated from saline-alkali soil collected in PR China, and it was designated as strain FJxs. Its optimal growth was observed at 37-40 °C in the presence of 0-3 % (w/v) NaCl (pH 7.0). The major fatty acids of strain FJxs were iso-C, iso-C 3OH, summed feature 3, C and iso-C G. The predominant respiratory quinone was menaquinone 6. The DNA G+C content of the strain was 45.18 mol%. Whole genome and 16S rRNA gene sequence analyses indicated that strain FJxs exhibited 94.78 % sequence identity (the maximum) with N-1-3-6, 94.36 % with 5DNS001, and 93.52 % with SCSIO 03483. Analyses of genotypic, phenotypic, phylogenetic and chemotaxonomic characteristics indicated that strain FJxs represented a novel species of the genus . This novel species was named sp. nov. with its type strain as FJxs (=CCTCC AB 2019251=KCTC 72740).
一株革兰氏阴性、兼性厌氧、非运动、杆状的菌株从中国盐碱地土壤中分离得到，命名为 FJxs 菌株。其最佳生长条件为 37-40°C、0-3%（w/v）NaCl（pH7.0）。FJxs 菌株的主要脂肪酸为 iso-C、iso-C 3OH、summed feature 3、C 和 iso-C G。主要呼吸醌为menaquinone 6。菌株的 DNA G+C 含量为 45.18 mol%。全基因组和 16S rRNA 基因序列分析表明，FJxs 菌株与 N-1-3-6 的序列相似度最高，为 94.78%（最大值），与 5DNS001 的相似度为 94.36%，与 SCSIO 03483 的相似度为 93.52%。基因型、表型、系统发育和化学分类特征分析表明，FJxs 菌株代表了属的一个新种。该新种命名为 sp. nov.，其模式菌株为 FJxs（=CCTCC AB 2019251=KCTC 72740）。
