A Gram-stain-negative, non-motile and ovoid or rod-shaped bacterial strain, DBTF-15 T , was isolated from a tidal flat sediment on the Yellow Sea in South Korea. Strain DBTF-15 T grew optimally at 25-30 °C, at pH 7.0-8.0 and in the presence of 2.0 % (w/v) NaCl. The phylogenetic trees based on 16S rRNA gene sequences revealed that strain DBTF-15 T joined the cluster comprising the type strains of species of the genus Palleronia. Strain DBTF-15 T exhibited higher 16S rRNA gene sequence similarity values to the type strains (96.5-96.7 %) of Maribius pelagius and Maribius salinus than to those (94.6-96.1 %) of the three species of the genus Palleronia. It exhibited 16S rRNA gene sequence similarity values of less than 93.9 % to the type strains of the other recognized species. Strain DBTF-15 T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The major polar lipids of strain DBTF-15 T were phosphatidylcholine, phosphatidylglycerol and one unidentified aminolipid. The DNA G+C content of strain DBTF-15 T was 68.7 mol%. The chemotaxonomic data and other differential phenotypic properties made it possible to distinguish strain DBTF-15 T from the genera Maribius and Palleronia. On the basis of the data presented, strain DBTF-15 T constitutes a novel genus and species within the class Alphaproteobacteria, for which the name Pseudomaribius aestuariivivens gen. nov., sp. nov. is proposed. The type strain is DBTF-15 T (=KACC 19431 T =NBRC 113039 T ).
