An aerobic, Gram-negative, catalase-positive, oxidase-positive bacterium was isolated from a dried seaweed sample collected from Kimnyeong Beach in Jeju, Republic of Korea. The cells of the organism, designated strain KY 101, were rods (0.4–0.5×1.2–2.7 μm) and motile by means of flagella. The colonies of the cells were 0.5–1 mm in diameter, smooth, circular, convex and light yellow in colour. The isolate showed growth at 10–40 °C, pH 6.1–12.1 and in the presence of 7 % NaCl. The major fatty acid was summed feature C 7/C 9/C 12 and the DNA G+C content was 60.4 mol%. 16S rRNA gene sequence studies showed that the organism was phylogenetically related to the family , with (99.1 % sequence similarity) as the closest neighbour. The level of DNA–DNA relatedness between strain KY 101 and DSM 15645 was 18.4–23.2 % (duplicate measurements). The combination of phenotypic differences and DNA–DNA hybridization data supports the suggestion that the isolate represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is strain KY 101 (=KACC 11904=JCM 14851).
