Abstract

A total of 52 strains of moderately halophilic bacteria isolated from hypersaline sediment of Lake Tebenquiche on the Atacama Saltern, Chile, were subjected to a taxonomic study. The morphological, physiological, biochemical and nutritional characteristics of the strains matched those described for the genus . Cells were Gram-negative, non-spore-forming, rod-shaped and motile. A black pigmentation was produced. One strain, designated LTS-4N, grew optimally at 32 °C. Growth occurred in media containing 0·5–25 % (w/v) total salts; the optimum was 7·5 % (w/v) total salts. The pH range for growth was 5–10. The G+C content of the DNA of strain LTS-4N was 59·8 mol%. Analysis of 16S rRNA gene sequence similarity revealed that strain LTS-4N was closely related to species; however, DNA–DNA hybridization of representative strain LTS-4N failed to associate the strain with any species of the genus with validly published names. Therefore, the name sp. nov. is proposed. The type strain is LTS-4N (=CECT 5315=DSM 14323).
