title: Aliidiomarina soli sp. nov., isolated from saline-alkaline soil.
abstract: A Gram-stain-negative, motile, non-spore-forming bacterium, designated strain Y4G10-17T, was isolated from the saline-alkali farmland top soil, Inner Mongolia, northern China. Strain Y4G10-17T could grow at 4-45 °C (with 30 °C as the optimal temperature), pH 6.0-12.0 (optimal at pH 9.0) and in the presence of 1.0-12.0 % (w/v) NaCl (optimal at 4.0-6.0 %). Phylogenetic analysis based on the eight different copies of the 16S rRNA gene sequences revealed that strain Y4G10-17T shared the highest sequence similarity with Aliidiomarina maris CF12-14T, 97.93-98.66 %, and lower than 97.0 % sequence similarity with all other type strains. Its major cellular fatty acids contained iso-C15 : 0, iso-C17 : 0, summed feature 9 (iso-C17 : 1ω9c and/or C16 : 0 10-methyl), iso-C15 : 1 F, iso-C11 : 0 3-OH and summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c). Q-8 was the predominantubiquinone. The major polar lipids of strain Y4G10-17T were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two unknown lipids and one unknown aminolipid. The genomic DNA G+C content was 49.3 mol%. DNA-DNA hybridization revealed that strain Y4G10-17T showed 20.2±5 % genomic DNA relatedness with its close relative A. maris CF12-14T. Based on the phenotypic, phylogenetic and genotypic characteristics, strain Y4G10-17T represents a novel species within the genus Aliidiomarina, for which the name Aliidiomarina soli sp. nov. is proposed. The type strain is Y4G10-17T (=CGMCC 1.15759T=KCTC 52381T).
