Abstract

A Gram-staining-negative, moderately halophilic bacterium, designated strain AN9, was isolated from a tidal flat of the Taean coast in South Korea. Cells were catalase- and oxidase-positive short rods that were motile by means of a single polar flagellum. Growth of strain AN9 was observed at 15–40 °C (optimum, 25–30 °C) and at pH 6.0–8.0 (optimum, pH 6.5–7.5). Strain AN9 contained ubiquinone Q-8 as the predominant isoprenoid quinone and C 3-OH (31.7 %), C 7 (24.8 %), C (14.7 %) and summed feature 3 (comprising C 7 and/or iso-C 2-OH, 10.72 %) as the major fatty acids. The G+C content of the genomic DNA of strain AN9 was 58 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain AN9 was related to members of the genus and was related most closely to IMCC1877 (96.8 % similarity). On the basis of chemotaxonomic and molecular data, strain AN9 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is AN9 (=KACC 13703 =DSM 22012).
