Abstract
A Gram-negative, motile, ovoid to rod-shaped bacterial strain, designated strain SMK-122T, was isolated from a Yellow Sea tidal flat located on the coast of Korea. Strain SMK-122T grew optimally at pH 7.0-8.0 and 30°C. It contained Q-10 as the predominant ubiquinone and possessed C18: 1ω7c and C16:0 as the major fatty acids. The DNA G + C content was 58.6 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain SMK-122T fell within the genus Roseovarius, being closest to Roseovarius nubinhibens ISMT; the sequence similarities with respect to Roseovarius species ranged from 94.9 to 97.3 %. The mean value for DNA-DNA relatedness between strain SMK-122T and Rva. nubinhibens DSM 15170T was 13%. Differential phenotypic properties of SMK-122T, together with its phylogenetic: and genetic distinctiveness, revealed that this strain is distinct from recognized Roseovarius species. On this basis, strain SMK-122T represents a novel species of the genus Rosebvarius, for which the name Roseovarius aestuarii sp. nov. is proposed. The type strain is SMK-122T (=KCTC 22174T = CCUG 55325T).
