Abstract

A novel halophilic archaeon, strain TL6, was isolated from Telega Lake, a hypersaline environment in Prahova county, Romania. Strain TL6 was able to grow in media with a salt concentration of between 2.5 and 5.2 M, with optimum growth at a concentration of 3.5 M. The novel strain was able to grow at concentrations of 1 M MgCl or less, with an optimum of 0.4 M Mg. Growth of the novel strain occurred between pH 6.0 and 8.5, with an optimum of pH 7.0–7.5. The G+C content of the total DNA was 63.7 mol%. The 16S rRNA gene sequence of the novel strain was most closely related to species of the genus (97.3–99.3 % sequence similarity). The lipid profile of the novel strain corresponded to that of other species belonging to the genus . A comparative analysis of the phenotypic properties and DNA–DNA hybridization between the novel strain and other species of the genus strongly supported the conclusion that strain TL6 represents a novel species within this genus, for which the name sp. nov., is proposed. The type strain is TL6 (=JCM 13924=DSM 18310).
