Abstract

A novel Gram-negative bacterium, designated MSW-14, was isolated from seawater collected around Mara Island, Jeju, Republic of Korea. The organism was motile by means of a flagellum and showed optimum growth at 0–4 % NaCl, 30 °C and pH 7.1. Phylogenetic analyses based on 16S rRNA gene sequences showed that the isolate belonged to the family . The strain's closest phylogenetic neighbours were JCS350 (97.7 % sequence similarity), SW-109 (97.3 %) and MSSRF26 (95.0 %). The dominant cellular fatty acid was C (summed feature 7, 52.8 %). The major ubiquinone was UQ-10. The DNA G+C content was 63.1 mol%. DNA–DNA hybridization values between strain MSW-14 and KCCM 42314 and KCTC 12311 were 26.0–27.3 % and 9.8–15.2 %, respectively. On the basis of the data from the polyphasic characterization, strain MSW-14 represents a novel species, for which the name sp. nov. is proposed. The type strain is MSW-14 (=KCTC 22370=DSM 21428).
