title: Mesonia ostreae sp. nov., isolated from seawater of an oyster farm, and emended description of the genus Mesonia.
abstract: A Gram-negative, aerobic, non-flagellated, non-gliding rod, designated T-y2(T), was isolated from seawater of an oyster farm in the South Sea, Korea. Strain T-y2(T) 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-y2(T) 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-y2(T) was 42.1 mol%. Strain T-y2(T) contained MK-6 as the predominant menaquinone and anteiso-C(15:0) and iso-C(15:0) as the major fatty acids. The only major phospholipid identified was phosphatidylethanolamine. The differential phenotypic properties and phylogenetic distinctiveness of strain T-y2(T) revealed that it is distinguishable from recognized members of the genus Mesonia. On the basis of the data presented here, strain T-y2(T) 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-y2(T) ( = KCTC 23500(T) = CCUG 60802(T)).
