title: Luteimonas dalianensis sp. nov., an obligate marine bacterium isolated from seawater.
abstract: A marine bacterial strain, designated OB44-3(T), was isolated from a crude oil-contaminated seawater sample collected near Dalian Bay, China. Cells of strain OB44-3(T) were Gramnegative, aerobic, rod-shaped, and oxidase- and catalasepositive. The major fatty acids were branched-chain saturated iso-C15:0 (27.9%) and unsaturated iso-C17:1 ω9c (14.8%). The DNA G+C content was 64.6 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain OB44-3(T) was a member of the genus Luteimonas (95-96% 16S rRNA gene sequence similarity); its closest neighbors were the type strains of Luteimonas terricola (96% sequence similarity), Luteimonas mephitis (96%), and Luteimonas lutimaris (96%). On the basis of phenotypic, chemotaxonomic, and phylogenetic distinctiveness, strain OB44-3(T) was considered to represent a novel species of the genus Luteimonas. The name Luteimonas dalianensis sp. nov. is proposed, with strain OB44-3(T) (=CGMCC 1.12191(T) =JCM 18136(T)) as the type strain.
