Phylogenetic trees based on the 16S rRNA gene sequence showed that strain MME-001T belonged to the genus Pseudoruegeria in the family Rhodobacteraceae and that it shared the highest 16S rRNA gene sequence similarity with Pseudoruegeria sabulilitoris GJMS-35T (98.0 % similarity of the 16S rRNA gene). Growth of strain MME-001T occurred in the presence of 1.0–7.0 % (w/v) NaCl at 15−40 °C and pH 7.0–9.0, with optimal growth in the presence of 2.0–3.0 % (w/v) NaCl at 25–30 °C and pH 7.0. Ubiquinone-10 was the major respiratory quinone. Major polar lipids were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and an unidentified lipid. The major cellular fatty acids were C18 : 1 ω7c and C16 : 0. The genomic DNA G+C content was 62 mol%. DNA-DNA hybridization values between strain MME-001T and P. sabulilitoris KCTC 42111T, ‘ Pseudoruegeria limi ’ KCTC 32460, Pseudoruegeria lutimaris KCTC 22690T, Pseudoruegeria aquimaris KCTC 12737T and Pseudoruegeriahaliotis KACC 17214T was 36±5, 57±7, 34±4, 18±5 and 21±3 %, respectively. Based on the phenotypic and phylogenetic taxonomical properties, this strain MME-001T represents a novel species of the genus Pseudoruegeria , for which the name Pseudoruegeria aestuarii sp. nov. is proposed. The type strain is MME-001T (=KCCM 43133T=JCM 30751T)., language=, type=
