title: Luteimonas marina sp. nov., isolated from seawater.
abstract: A marine bacterial strain, designated FR1330(T), was isolated from a seawater sample collected near Ganghwa Island, the Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain FR1330(T) belonged to the Gammaproteobacteria and was related to the genus Luteimonas; its closest neighbours were the type strains of Luteimonas composti (97.9 % sequence similarity) and Luteimonas mephitis (95.0 %). DNA-DNA relatedness values for strain FR1330(T) with Luteimonas composti CC-YY255(T) and Luteimonas mephitis KACC 11391(T) were 33 and 10 %, respectively. Cells of strain FR1330(T) were Gram-negative, aerobic, rod-shaped and oxidase- and catalase-positive. The predominant respiratory lipoquinone was ubiquinone-8. The major fatty acids were branched-chain saturated iso-C(15 : 0) (26.2 %) and unsaturated iso-C(17 : 1)omega9c (26.0 %). The DNA G+C content was 67.6 mol%. On the basis of several phenotypic characteristics, strain FR1330(T) could be differentiated from Luteimonas composti and Luteimonas mephitis. The data obtained from the polyphasic study demonstrated clearly that strain FR1330(T) represents a novel species of the genus Luteimonas. The name Luteimonas marina sp. nov. is proposed, with strain FR1330(T) (=KCTC 12327(T)=JCM 12488(T)=IMSNU 60306(T)) as the type strain.
