Abstract

A novel halophilic archaeon, strain EJ-32, was isolated from water from Lake Ejinor in Inner Mongolia, China. The taxonomy of strain EJ-32 was studied by using a polyphasic approach. On the basis of 16S rRNA gene sequence similarities, strain EJ-32 was shown to be phylogenetically related to (97.9 %), (97.9 %), (97.8 %), (97.8 %), (97.6 %), (97.4 %), (97.1 %) and (96.4 %). Strain EJ-32 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 species were ≤49 %, indicating that EJ-32 constitutes a different genospecies. The data show that strain EJ-32 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is EJ-32 (=CECT 7194=CGMCC 1.6782=JCM 14265).
