title: Jindonia aestuariivivens gen. nov., sp. nov., isolated from a tidal flat on the south-western sea in Republic of Korea.
abstract: A Gram-stain-negative, aerobic, non-flagellated, and coccoid, ovoid or rod-shaped bacterium, designated JDTF-65T, was isolated from a tidal flat on the south-western sea in Republic of Korea. Strain JDTF-65Tgrew optimally at 25°C, at pH 7.0-8.0 and in the presence of 2.0% (w/v) NaCl. Strain JDTF-65Texhibited 16S rRNA gene sequence similarities of 97.1-97.6% to the type strains of 'Aliisedimentitalea scapharcae', Phaeobacter gallaeciensis, Phaeobacter inhibens, Leisingera aquimarina, Tropicibacter litoreus, Sulfitobacter pseudonitzschiae, and Pseudoseohaeicola caenipelagi. Phylogenetic trees based on 16S rRNA gene sequences showed that strain JDTF-65Tforms an independent lineage within the radiation enclosed by the family Rhodobacteraceae. Strain JDTF-65Tcontained Q-10 as the predominant ubiquinone and C18:1ω7c as the major fatty acid. The major polar lipids of strain JDTF-65Twere phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, one unidentified aminolipid, and one unidentified lipid. The DNA G+C content of strain JDTF-65Twas 56.8 mol% and its DNA-DNA relatedness values with the type strains of the phylogenetically related species were 13-27%. Differential phenotypic properties revealed that strain JDTF-65Tis separated from representatives of some phylogenetically related taxa. On the basis of the data presented, strain JDTF-65Trepresents a new genus and species within the family Rhodobacteraceae, for which the name Jindonia aestuariivivens gen. nov., sp. nov. is proposed. The type strain of Jindonia aestuariivivens is JDTF-65T(=KCTC 52564T=NBRC 112534T).
