abstract= A Gram-stain-negative, strictly aerobic bacterium, designated KJ21T, was isolated from a tidal flat in South Korea. Cells were non-motile rods showing oxidase- and catalase-positive activities. Growth of strain KJ21T was observed at 10–35 °C (optimum, 30 °C), at pH 6.0–8.5 (optimum, pH 7.0) and in the presence of 1–5 % (w/v) NaCl (optimum, 2 %). Strain KJ21T contained summed feature 8 (comprising C18 : 1ω7c/C18  : 1ω6c), C16 : 0, 10-methyl C19 : 0 and C10 : 0 3-OH as the major fatty acids and ubiquinone-10 as the major isoprenoid quinone. Phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine, an unknown aminolipid and an unknown lipid were detected as the major polar lipids. The G+C content of the genomic DNA was 53.9 mol%. Phylogenic analysis based on 16S rRNA gene sequences showed that strain KJ21T formed a tight phylogenetic lineage with the members of the genus Pacificibacter with a 100 % bootstrap value. Strain KJ21T was most closely related to Pacificibacter maritimus KMM 9031T (98.7 %) and Pacificibacter marinus HDW-9T (98.4 %), and the DNA–DNA relatedness values between strain KJ21T and the type strains of P. maritimus and P. marinus were 46.9±4.2 % and 39.8±5.7, respectively. On the basis of phenotypic, chemotaxonomic and molecular properties, it is clear that strain KJ21T represents a novel species of the genus Pacificibacter , for which the name Pacificibacter aestuarii sp. nov. is proposed. The type strain is KJ21T (=KACC 19098T=JCM 31805T).,
