abstract= A Gram-stain-negative, aerobic, non-motile and coccoid-, ovoid- or rod-shaped bacterial strain, designated SSKS-13T, was isolated from sediment sampled at the junction between the ocean and a freshwater spring at Jeju island, Republic of Korea. Strain SSKS-13T grew optimally at 37 °C and in the presence of 2.0 % (w/v) NaCl. A neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strain SSKS-13T fell within the clade comprising the type strains of Altererythrobacter species, clustering with the type strains of Altererythrobacter lauratis , Altererythrobacter palmitatis and Altererythrobacter buctensis having 16S rRNA gene sequence similarities of 97.2–97.6 %. Strain SSKS-13T exhibited 16S rRNA gene sequence similarities of less than 97.0 % to the type strains of the other recognized species. Strain SSKS-13T contained Q-10 as the predominant ubiquinone and C18 : 1  ω7c as the major fatty acid. The major polar lipids detected in strain SSKS-13T were phosphatidylethanolamine, phosphatidylglycerol and sphingoglycolipid. The DNA G+C content of strain SSKS-13T was 64.6 mol%. The mean DNA–DNA relatedness values of strain SSKS-13T with the type strains of A. lauratis , A. palmitatis and A. buctensis were 11.7–25.3 %. Differential phenotypic properties, together with the phylogenetic and genetic data, proved that strain SSKS-13T is distinct from recognized Altererythrobacter species. On the basis of the data presented here, strain SSKS-13T is considered to represent a novel species of the genus Altererythrobacter , for which the name Altererythrobacter aquimixticola sp. nov. is proposed. The type strain is SSKS-13T (=KACC 19863T=KCTC 62900T=NBRC 113545T).,
