Abstract
A Gram-stain-negative bacterium, designated strain CBA4601T, was isolated from a seawater sample obtained off the coast of Jeju Island, Korea. The organism grew in the presence of 0–4 % (w/v) NaCl and at 20–35 °C and pH 7.0–9.0, with optimal growth in 2 % NaCl, and at 25 °C and pH 8.0. Phylogenetic trees based on 16S rRNA gene sequences showed that strain CBA4601T was related to the genus Ferrimonas within the class Gammaproteobacteria . 16S rRNA gene sequence similarity between strain CBA4601T and Ferrimonas marina A4D-4T, the most closely related species, was 96.9 %. The G+C content of the genomic DNA from strain CBA4601T was 54.2 mol%, and the isoprenoid quinones menaquinone 7 (MK-7), ubiquinone 7 (Q-7) and ubiquinone 8 (Q-8) were detected. The major fatty acids were C17 : 1ω8c, C18 : 1ω9c and C16 : 0, and the major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and an unidentified ninhydrin-positive phospholipid. On the basis of this taxonomic study using a polyphasic approach, strain CBA4601T represents a novel species of the genus Ferrimonas , for which the name Ferrimonas pelagia sp. nov. is proposed. The type strain is CBA4601T ( = KACC 16695T = KCTC 32029T = JCM 18401T).
