A Gram-stain-negative, aerobic, non-spore-forming, non-flagellated and rod-shaped or ovoid bacterial strain, designated BG-MY13T, was isolated from a tidal flat sediment on the South Sea, South Korea. Strain BG-MY13T grew optimally at 30–35 °C, at pH 7.0–8.0 and in the presence of 2.0–3.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain BG-MY13T falls within the cluster comprising the type strains of species of the genus Gramella . Strain BG-MY13T exhibited 16S rRNA gene sequ4ence similarity values of 96.9–97.8 % to the type strains of Gramella echinicola , Gramella gaetbulicola , Gramella portivictoriae and Gramella marina and of 94.6–96.5 % to the type strains of other species of the genus Gramella with validly published names. Strain BG-MY13T contained MK-6 as the predominant menaquinone and iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids.
