Abstract
Four heterotrophic bacterial strains belonging to the globally distributed marine RCA (Roseobacter clade-affiliated) cluster (family Rhodobacteraceae, class Alphaproteobacteria) were obtained from coastal seawater samples. Strain RCA23T was isolated from a 10”7 dilution culture inoculated with seawater from the German Wadden Sea (southern North Sea), reflecting the high abundance of RCA bacteria in this habitat. Strains IMCC1909, IMCC1923 and IMCC1933 were isolated from diluted seawater (10”3) of the Yellow Sea, South Korea. Based on 16S rRNA gene sequence comparison, Octadecabacter antarcticus 307T is the closest described relative of the RCA strains, with 95.4?95.5% sequence similarity. Cells of RCA23T, IMCC1909, IMCC1923 and IMCC1933 are small motile rods requiring sodium ions. Optimal growth of RCA23T occurs at 25 6C and within a very narrow pH range (pH 7?8, optimum pH 7.5). The DNA G+C base content of RCA23T is 53.67 mol%. The major respiratory lipoquinone is ubiquinone-10 (Q-10)
