Abstract
A Gram-negative, aerobic, non-flagellated, non-gliding rod, designated T-y2T, was isolated from seawater of an oyster farm in the South Sea, Korea. Strain T-y2T grew optimally at 25 °C, at pH 7.0–7.5 and with 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain T-y2T belonged to the genus Mesonia and exhibited 94.3–96.4 % 16S rRNA gene sequence similarity with the type strains of species of the genus Mesonia . The DNA G+C content of strain T-y2T was 42.1 mol%. Strain T-y2T contained MK-6 as the predominant menaquinone and anteiso-C15 : 0 and iso-C15 : 0 as the major fatty acids. The only major phospholipid identified was phosphatidylethanolamine. The differential phenotypic properties and phylogenetic distinctiveness of strain T-y2T revealed that it is distinguishable from recognized members of the genus Mesonia . On the basis of the data presented here, strain T-y2T is considered to represent a novel species of the genus Mesonia , for which the name Mesonia ostreae sp. nov. is proposed. The type strain is T-y2T ( = KCTC 23500T = CCUG 60802T).
