Abstract

A Gram-positive, motile, round to ellipsoidal, endospore-forming, rod-shaped bacterial strain, SF-57, was isolated from a marine solar saltern in Korea. This organism grew between 4 and 39 °C, with optimum growth at 30 °C. Strain SF-57 grew in the presence of 0·5–15·0 % NaCl, with optimum growth at 2–3 % NaCl. The peptidoglycan type of strain SF-57 was A1 linked directly through -Lys. In strain SF-57, menaquinone-7 (MK-7) was the predominant isoprenoid quinone and anteiso-C was the major fatty acid. The DNA G+C content was 41·8 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain SF-57 formed a coherent cluster with , with a bootstrap resampling value of 100 %. The level of 16S rRNA gene sequence similarity between strain SF-57 and DSM 1297 was 98·9 %. The mean DNA–DNA relatedness level between strain SF-57 and the type strain of was 20·6 %. Based on phenotypic properties, phylogenetic analyses and genomic data, strain SF-57 merits placement in the genus as a representative of a novel species, for which the name sp. nov. is proposed. The type strain is SF-57 (=KCCM 41644=JCM 11810).
