This isolate was neutrophilic, motile and grew in a wide range of MgCl2 concentrations (0·005–1·0 M). The major polar lipids of the isolate were C20C20 and C20C25 derivatives of phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and phosphatidylglycerol sulfate. A comprehensive 16S rRNA gene sequence analysis revealed that the isolate shared 96·6–97·7 % sequence identity with Natrinema species. The isolate, however, could be genetically differentiated from these species by DNA–DNA hybridization analysis and on the basis of its physiological properties. On the basis of the polyphasic evidence, strain AJ2T (=AS 1.3731T=JCM 12890T) represents the type strain of a novel species, for which the name Natrinema altunense sp. nov. is proposed. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.63622-0
