A novel halophilic archaeon, strain EJ-32T, was isolated from water from Lake Ejinor in Inner Mongolia, China. The taxonomy of strain EJ-32T was studied by using a polyphasic approach. On the basis of 16S rRNA gene sequence similarities, strain EJ-32T was shown to be phylogenetically related to Halorubrum coriense (97.9 %), Halorubrum trapanicum (97.9 %), Halorubrum sodomense (97.8 %), Halorubrum tebenquichense (97.8 %), Halorubrum xinjiangense (97.6 %), Halorubrum terrestre (97.4 %), Halorubrum distributum (97.1 %) and Halorubrum saccharovorum (96.4 %). Strain EJ-32T was found to be neutrophilic, non-motile and Gram-negative. It grew in medium containing saturation concentrations of NaCl and did not require magnesium for optimal growth. The G+C content of the DNA is 64.0 mol%. Values for DNA–DNA hybridization with respect to phylogenetically related Halorubrum species were 
49 %, indicating that EJ-32T constitutes a different genospecies. The data show that strain EJ-32T represents a novel species of the genus Halorubrum, for which the name Halorubrum ejinorense sp. nov. is proposed. The type strain is EJ-32T (=CECT 7194T=CGMCC 1.6782T=JCM 14265T).
