A Gram-stain-negative, aerobic, chemoheterotrophic, yellow, non-motile and flexirubin-positive bacterium, designated strain IMCC12008(T), was isolated from coastal seawater of the Yellow Sea and subjected to polyphasic taxonomy. Optimal growth was observed at 25 degrees C, pH 7.0 and in the presence of 2% (w/v) NaCl. Based on 16S rRNA gene sequence analysis and subsequent phylogenetic analyses, strain IMCC12008(T) belonged to the genus Ulvibacter of the family Flavobacteriaceae, with Ulvibacter antarcticus IMCC3101(T) (96.0%) and Ulvibacter litoralis KMM 3912(T) (95.8%) having the highest sequence similaries. The major fatty acids were iso-C-15:0 (26.2%) and iso-C-15:1 G (10.5%). The DNA G+C content was 38.1 mol%. Strain IMCC12008(T) contained menaquinone-6 (MK-6) as the respiratory quinone, and polar lipids comprising phosphatidylethanolamine, two unidentified aminolipids and an unknown aminophospholipid. On the basis of data collected from this study, strain IMCC12008(T) (=NBRC 109484(T)=KCTC 32322(T)) represents a novel species of the genus Ulvibacter, for which the name Ulvibacter marinus sp. nov. is proposed.
