Abstract

A Gram-stain-negative, non-motile, aerobic, curved-to-spiral-rod-shaped bacterium, designated AH-MY2, was isolated from a tidal flat on Aphae island in the sea to the south-west of South Korea, and its taxonomic position was investigated using a polyphasic taxonomic approach. Strain AH-MY2 grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2.0 % (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain AH-MY2 clustered with the type strain of and that this cluster joined the clade comprising the type strains of species of the genus . Strain AH-MY2 exhibited 16S rRNA gene sequence similarity values of 90.6 % to the type strain of and of less than 91.0 % to the type strains of other species with validly published names. Strain AH-MY2 contained Q-10 as the predominant ubiquinone and Cω7 as the major fatty acid. The major polar lipids detected in strain AH-MY2 were phosphatidylglycerol, phosphatidylethanolamine, two unidentified aminolipids and one unidentified glycolipid. The DNA G+C content of strain AH-MY2 was 56.0 mol%. The phylogenetic data and differential chemotaxonomic and other phenotypic properties revealed that strain AH-MY2 represented a novel genus and species within the family of the class , for which the name gen. nov., sp. nov. is proposed. The type strain of is AH-MY2 ( = KCTC 32577 = CECT 8488).
