Altererythrobacter marensis sp. nov., isolated from seawater.
A novel Gram-negative bacterium, designated MSW-14(T), 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 degrees C and pH 7.1. Phylogenetic analyses based on 16S rRNA gene sequences showed that the isolate belonged to the family Erythrobacteraceae. The strain's closest phylogenetic neighbours were Altererythrobacter epoxidivorans JCS350(T) (97.7 % sequence similarity), Altererythrobacter luteolus SW-109(T) (97.3 %) and Altererythrobacter indicus MSSRF26(T) (95.0 %). The dominant cellular fatty acid was C(18 : 1) (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(T) and A. epoxidivorans KCCM 42314(T) and A. luteolus KCTC 12311(T) were 26.0-27.3 % and 9.8-15.2 %, respectively. On the basis of the data from the polyphasic characterization, strain MSW-14(T) represents a novel species, for which the name Altererythrobacter marensis sp. nov. is proposed. The type strain is MSW-14(T) (=KCTC 22370(T)=DSM 21428(T)).
