A Gram-negative, aerobic, halophilic bacterium, designated strain Iso 3T, was isolated from the East Sea in Korea. Strain Iso 3T was motile by means of polar flagella, occasionally formed rosette-like aggregates and contained 18: 1 ω7c as the dominant cellular fatty acid. Strain Iso 3T grew at NaCI concentrations of 1 - 10 % and temperatures of 4-30°C. The optimal growth temperature was 20°C. Analysis of the 16S rRNA gene sequence revealed that this strain is affiliated with a subcluster of the Alphaproteobacteria. However, strain Iso 3T generated metabolic energy by sulfide oxidation. The 16S rRNA gene sequence similarity between strain Iso 3T and the type strain of the most closely related species, Sulfitobacter pontiacus, was 97.7 %. DNA-DNA relatedness between strain Iso 3T and Sulfitobacter pontiacus, DSM 10014T was 24.1 %. On the basis of phenotypic properties and phylogenetic distinctiveness, strain Iso 3T is classified within a novel Sulfitobacter species, for which the name Sulfitobacter litoralis sp. nov. is proposed, with the type strain Iso 3T (=KCTC 12521T =DSM 17584T).
