title: Ulvibacter marinus sp. nov., isolated from coastal seawater.
abstract: 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 °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.
