N2 - Two novel strains were isolated from the mudflat of Suaeda japonica colonies in Incheon, Republic of Korea. Designated as DGU5T and DGU6T, these strains were Gram-stain-negative, facultatively anaerobic and rod-shaped and had yellowish colonies. Both strains were determined to belong to the genus Aurantiacibacter through phylogenetic analysis of their 16S rRNA sequences and draft genomes. The cells of strain DGU5T were non-motile and grew at temperatures ranging between 7–45°C (optimum, 25–30°C), pH 6.0–10.0 (optimum, 7.0–8.0) and in the presence of 0–11.0% NaCl (optimum, 2.0%). The cells of strain DGU6T were non-motile and grew in temperatures ranging from 10–45 °C (optimum, 30–35°C), pH 3.0–10.0 (optimum, 7.0–8.0) and in the presence of 0–11.0% NaCl (optimum, 2.0%). Overall genome relatedness index calculations revealed average nucleotide identity values (72.3–88.6%) and digital DNA–DNA hybridization values (18.8–35.9%) aligning with those of the genus Aurantiaci-bacter. The major fatty acids in both strains were C17:1 ω6c and summed feature 8 (C18:1 ω6c/C18:1 ω7c), while the predominant polar lipids were sphingoglycolipid, phosphatidylglycerol, and diphosphatidylglycerol. Phylogenetic, average nucleotide identity, digital DNA–DNA hybridization, physiological, and biochemical data collectively demonstrated the distinctiveness of the novel strains from other members within the family Erythrobacteraceae. We propose the names A. flavus sp. nov. (type strain DGU5T = KACC 23720T = TBRC 19015T) and A. gilvus sp. nov. (type strain DGU6T = KACC 23721T = TBRC 19016T) for the two strains.
