Marinibacillus campisalis sp. nov., a moderate halophile isolated from a marine solar saltern in Korea, with emended description of the genus Marinibacillus
A Gram-positive, motile, round to ellipsoidal, endospore-forming, rod-shaped bacterial strain, SF-57T, 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-57T grew in the presence of 0·5–15·0 % NaCl, with optimum growth at 2–3 % NaCl. The peptidoglycan type of strain SF-57T was A1α linked directly through l-Lys. In strain SF-57T, menaquinone-7 (MK-7) was the predominant isoprenoid quinone and anteiso-C15 : 0 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-57T formed a coherent cluster with Marinibacillus marinus, with a bootstrap resampling value of 100 %. The level of 16S rRNA gene sequence similarity between strain SF-57T and M. marinus DSM 1297T was 98·9 %. The mean DNA–DNA relatedness level between strain SF-57T and the type strain of M. marinus was 20·6 %. Based on phenotypic properties, phylogenetic analyses and genomic data, strain SF-57T merits placement in the genus Marinibacillus as a representative of a novel species, for which the name Marinibacillus campisalis sp. nov. is proposed. The type strain is SF-57T (=KCCM 41644T=JCM 11810T).
