Abstract

A novel, extremely halophilic archaeon, D43, was isolated from traditional salt-fermented seafood in Korea. The cells were Gram-negative-staining and motile. The strain grew at 15–50 °C, 10–30 % (w/v) NaCl and pH 6.0–8.0. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain D43 is affiliated with the family in the domain and had 95.5 % 16S rRNA gene sequence similarity with DX253. The sequence from strain D43 formed a clade with those from regardless of which tree-generating algorithm was used. DNA–DNA hybridization experiments showed 25.8 % relatedness between the isolate and KCTC 4006. Major lipids were phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and two unidentified glycolipids. The DNA G+C content of the isolate was 56.5 mol%. On the basis of this polyphasic taxonomic study, strain D43 represents a novel species in the genus , for which the name sp. nov. is proposed. The type strain is D43 (=DSM 19505 =JCM 15962).
