abstract= A Gram-staining-negative, non-motile, aerobic bacterial strain, designated Y3L17T, was isolated from the saline–alkaline soil of a farmland, Hangjin Banner, Inner Mongolia, northern China. Y3L17T could grow at 15–45 °C (optimum 35 °C), pH 6.0–10.0 (optimum pH 8.0) and with 0–4 % (w/v) NaCl (optimum 0 %). The results of phylogenetic analysis based on the 16S rRNA gene and gyrB gene sequences revealed that Y3L17T tightly clustered with strains of members of the genus Arenimonas , sharing the highest 16S rRNA gene similarities with Arenimonas aestuarii S2-21T (99.5 %) and Arenimonas donghaensis HO3-R19T (98.2 %), and lower similarities (<97 %) with all the other type strains of species of this genus. However, Y3L17T shared only 92.62 % gyrB gene similarities with A. aestuarii S2-21T. The DNA–DNA hybridization values of Y3L17T with A. aestuarii S2-21T and A. donghaensis HO3-R19T were 20.1±2.5 and 18.2±3.2 %, respectively. Y3L17T contained phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, five unknown phospholipids and one unknown lipid as the major polar lipids. Ubiquinone-8 (Q-8) was the predominant respiratory quinone, while iso-C15 : 0, iso-C17 : 0ω9c and iso-C11 : 0 3-OH were the major cellular fatty acids. Its genomic DNA G+C content was 65.4 mol%. On the basis of its phenotypic, phylogenetic and genotypic characteristics, Y3L17T represents a novel species within the genus Arenimonas , for which the name Arenimonas soli sp. nov. is proposed, the type strain is Y3L17T (=CGMCC 1.15905T =KCTC 52420T).,
