Abstract

A Gram-positive, aerobic, non-motile, rod-shaped actinomycete, designated strain DSW-2, was isolated from a seaweed sample collected around Mara Island, Jeju, Republic of Korea. Comparative 16S rRNA gene sequence analysis showed that strain DSW-2 belongs to the suborder and forms a distinct clade separated from representatives of the several families of this order. Levels of 16S rRNA gene sequence similarity between the novel strain and members of this suborder were lower than 96.4 %. The peptidoglycan type is A3 with Lys–Ser as the interpeptide bridge. Whole-cell sugars are glucose and galactose. The major menaquinone is MK-9(H). The predominant fatty acid is ai-C. The polar lipids are phosphatidylglycerol and phosphatidylinositol. The DNA G+C content was 68.3 mol%. On the basis of the chemotaxonomic markers and phylogenetic distinctiveness presented here, it is evident that the isolate represents a novel taxon within the suborder . The name gen. nov., sp. nov. is proposed, with the type strain DSW-2 (=KCTC 13436 =DSM 22126).
