Abstract

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