Abstract

A novel haloalkaliphilic archaeon, strain DZ-1, was isolated from a soda lake in Xinjiang, China. The taxonomy of strain DZ-1 was studied by polyphasic methods. According to 16S rRNA gene sequence similarity, strain DZ-1 was phylogenetically related to (97·5 %), (95·7 %) and (95·9 %). Strain DZ-1 was able to grow at 20–44 °C and was also physiologically different from the above-mentioned species with respect to assimilation of sugars and utilization of organic acids. The DNA G+C content of strain DZ-1 was 62·1 mol% ( ). The DNA–DNA relatedness of strain DZ-1 to and was 22 and 13 %, respectively. It was concluded that strain DZ-1 represents a novel species of the genus , for which the name (type strain, DZ-1=AS 1.3528=JCM 12358) is proposed.
