title: Paradonghicola geojensis gen. nov., sp. nov., isolated from seawater, Geoje-si, South Korea.
abstract: 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 C18:1 ω7c (51.7 %), C16:0 (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)).
