Paradonghicola geojensis gen. nov., sp. nov., isolated from seawater, Geoje-si, South Korea

A Gram-negative, non-motile, non-spore-forming and aerobic bacterium, designated FJ12 T , was isolated from seawater, Geoje-si, South Korea. Strain FJ12 T was catalase and oxidase positive. Growth of strain FJ12 T was optimally observed at 30 °C and pH 6 and grew in the presence of 0–11 % (w/v) NaCl (optimum 2–3 % NaCl). The phylogenic analysis based on 16S rRNA gene sequence of strains FJ12 T showed the highest sequence similarity to those of Doghicola eburneus KCTC 12735 T (95.4 %), Aestuariihabitans beolgyonensis KTCT 32324 T (95.3 %), Sulfitobacter pontiacus KCTC 32185 T (94.9 %), Roseisalinus antarcticus DSM 11466 T (94.8 %) and Loktanella soesokkaensis KCTC 32425 T (94.7 %). The major polar lipids of FJ12 T were phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, an unidentified aminolipid and unidentified lipids. It contained Q-10 as the predominant ubiquinone, and major fatty acid is C 18:1 ω 7c (51.7 %), C 16:0 (24.0 %). The DNA G+C content of the strain FJ12 T was 60 mol%. Based on physiological and chemotaxonomic characteristics, strain FJ12 T should be regarded as the type species of a novel genus in the family Rhodobacteraceae for which the name Paradonghicola geojensis sp. nov. is proposed. The type strain FJ12 T (=KEMB 3001-336 T =JCM 30384 T ).
