A moderately halophilic Gram-negative bacterium, strain DS2T, was isolated from seawater from the East Sea in Korea. Strain DS2T grew at salinities of 0–14 % (w/v) NaCl and at temperatures in the range 10–38 °C. The cells were non-motile short rods (1.0–1.4 µm in width and 1.6–2.6 µm in length) and the major fatty acids were C18 : 1
7c and 11-methyl C18 : 1
7c. The genomic DNA G+C content was 72.0 mol% and the predominant lipoquinone was Q-10. The major cellular phospholipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DS2T formed a distinct phyletic line from the genus Rubrimonas within the Alphaproteobacteria. The levels of 16S rRNA gene sequence similarity with respect to the type strains of related genera were below 94 %. On the basis of physiological and phylogenetic properties, strain DS2T represents a novel genus and species of the Alphaproteobacteria, for which the name Albimonas donghaensis gen. nov., sp. nov. is proposed. The type strain is DS2T (=KCTC 12586T=DSM 17890T).

A transmission electron micrograph of cells of strain DS2T is available as a supplementary figure with the online version of this paper.
