ABSTRACT
A haloalkaliphilic strain (IM 1326T) was isolated from brine sampled at a soda lake in the Inner Mongolia Autonomous Region, China. Cells of the strain were rod-shaped and motile. Strain IM 1326T was able to grow at 4-42 °C (optimum, 37 °C) with 0-13.0â% (w/v) NaCl concentrations (optimum at 4.0-6.0â%) and at pH 7.5-11.0 (optimum at 9.0-10.0). The 16S rRNA gene phylogenetic analysis revealed that the isolate belongs to the genus Aliidiomarina and is closely related to the type strains of Aliidiomarina sanyensis (95.8â% sequence similarity), Aliidiomarina shirensis (95.7â%), Aliidiomarina iranensis (95.4â%) and Aliidiomarina haloalkalitolerans (95.3â%). The whole genome of strain IM 1326T was sequenced, and the genomic DNA G+C content was 49.7âmol%. Average nucleotide identity, average amino acid identity and digital DNA-DNA hybridization values between the isolate and the related Aliidiomarina species were 68.1-84.9â%, 76-78â% and 18.4-20.4â%, respectively. The respiratory quinone was ubiquinone-8. The polar lipid profile included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and one unidentified aminophospholipid. The predominant cellular fatty acids were summed feature 9 (10-methyl-C16ââ0/iso-C17ââ1 ω9c, 22.2â%), iso-C15ââ0 (16.1â%) and iso-C17ââ0 (13.1â%). Based on the results of phylogenetic analysis, genome relatedness, and the physiological and chemotaxonomic properties of the isolate, strain IM 1326T is considered to represent a novel species of the genus Aliidiomarina, for which the name Aliidiomarina halalkaliphila sp. nov. is proposed (type strain IM 1326T=CGMCC 1.17056T=JCM 34227T).
