Abstract

Two Gram-negative, rod-shaped bacterial strains, MSS-160 and MSS-161, were isolated from a marine solar saltern in the Yellow Sea, Korea, and subjected to a polyphasic taxonomic study. The two strains grew optimally in the presence of 2 % (w/v) NaCl and at 25–30 °C. Strains MSS-160 and MSS-161 contained MK-7 as the predominant menaquinone and large amounts of fatty acids C 7 and/or iso-C 2-OH and iso-C. The DNA G+C content of the two strains was 41 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that the two strains were phylogenetically affiliated to the genus . Strains MSS-160 and MSS-161 exhibited no difference in their 16S rRNA gene sequences and possessed a mean DNA–DNA relatedness level of 91 %; they exhibited 16S rRNA similarity levels of 96·6–99·3 % to the type strains of species with validly published names. DNA–DNA relatedness levels between the two strains and the type strains of five species were lower than 46 %. On the basis of phenotypic, phylogenetic and genetic data, strains MSS-160 and MSS-161 were classified in the genus as members of a novel species, for which the name sp. nov. (type strain, MSS-160=KCTC 12309=JCM 12598) is proposed.
