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 0-4â% (w/v) NaCl (optimum 0â%). 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 (99.5â%) and Arenimonas donghaensis HO3-R19T (98.2â%), and lower similarities (<97â%) with all the other type strains of species of this genus. However, Y3L17T shared only 92.62â% gyrB gene similarities with A. aestuarii S2-21T. The DNA-DNA hybridization values of Y3L17T with A. aestuariiS2-21T and A. donghaensis HO3-R19T were 20.1±2.5 and 18.2±3.2â%, 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-C15ââ0, iso-C17ââ0ω9c and iso-C11ââ0 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).
