N2 - A yellow-coloured bacterium, designated as strain JGD-13T, was isolated from a tidal flat in the Republic of Korea. Cells were Gram-stain-negative, aerobic, non-flagellated and rod-shaped. Growth was observed at 4–42 °C (optimum, 30 °C), at pH 6.0– 12.0 (pH 7.0–8.0) and at 1–7% (w/v) NaCl concentration (3%). The 16S rRNA gene sequence analysis indicated that strain JGD-13T was closely related to Aurantiacibacter gangjinensis K7-2T with a sequence similarity of 98.2%, followed by Aurantiacibacter aquimixticola JSSK-14T (98.1%), Aurantiacibacter atlanticus s21-N3T (97.6%), Aurantiacibacter zhengii V18T (97.6%) and Aurantiacibacter luteus KA37T (97.5%). The average nucleotide identity and digital DNA–DNA hybridization values with related strains were 70.3–76.2% and 18.5–20.3%. The genomic DNA G+C content was 60.2 mol%. Phylogenetic analysis using the maximum-likelihood method showed that strain JGD-13T formed a clade with A. aquimixticola JSSK-14T and A. gangjinensis K7-2T. The major fatty acids were summed feature 8 (39.7%) and C17:1 ω6c (14.4%). The predominant respiratory quinone was ubiquinone-10. The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, one sphingoglycolipid and three unidentified lipids. On the basis of phylogenetic, phenotypic and chemotaxonomic characteristics, strain JGD13T represents a novel species within the genus Aurantiacibacter, for which the name Aurantiacibacter sediminis JGD-13Tsp. nov. is proposed. The type strain is JGD-13T (=KCTC 72892T=KACC 21676T=JCM 33995T).
