Halorubrum tebenquichense sp nov., a novel halophilic archaeon isolated from the Atacama Saltern, Chile. INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY, 52 (1), 149-155. https://doi.org/10.1099/00207713-52-1-1491466-50261466-5034https://hdl.handle.net/20.500.12740/25437A novel extremely halophilic archaeon was isolated from Lake Tebenquiche, situated in the northern part of the Atacama Saltern, Chile. The cells of these micro-organisms were mostly irregularly disc-shaped. They grew in medium containing saturated concentrations of NaCl and did not require magnesium for optimal growth. The polar lipid composition revealed the presence of mannosyl-2-sulfate-(1-4)-glycosyl-archaeol, the main glycolipid of the genus Halorubrum, and two new glycolipids. The G+C content of the DNA was 63.2 mol%. Phylogenetic analysis of the 16S rRNA gene placed strain ALT6-92(T) within the Halorubrum cluster. The low DNA-DNA hybridization value justified classification in a new species for which the name Halorubrum tebenquichense sp. nov. is proposed. The type strain is ALT6-92(T) (= CECT 5317(T) = DSM 14210(T)).enextremely halophilic archaeahalorubrum tebenquichenseLake TebenquicheAtacama SalternArticulohttps://doi.org/10.1099/00207713-52-1-149
