<i>Ulvibacter marinus</i> sp. nov., isolated from coastal seawater

다국어 초록 (Multilingual Abstract)

<P>A Gram-stain-negative, aerobic, chemoheterotrophic, yellow, non-motile and flexirubin-positive bacterium, designated strain IMCC12008<SUP>T</SUP>, 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<SUP>T</SUP> belonged to the genus <I>Ulvibacter</I> of the family <I>Flavobacteriaceae</I>, with <I>Ulvibacter antarcticus</I> IMCC3101<SUP>T</SUP> (96.0 %) and <I>Ulvibacter litoralis</I> KMM 3912<SUP>T</SUP> (95.8 %) having the highest sequence similaries. The major fatty acids were iso-C<SUB>15 : 0</SUB> (26.2 %) and iso-C<SUB>15 : 1</SUB> G (10.5 %). The DNA G+C content was 38.1 mol%. Strain IMCC12008<SUP>T</SUP> 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<SUP>T</SUP> ( = NBRC 109484<SUP>T</SUP> = KCTC 32322<SUP>T</SUP>) represents a novel species of the genus <I>Ulvibacter</I>, for which the name <I>Ulvibacter marinus</I> sp. nov. is proposed.</P>
