Abstract

A novel actinomycete, strain KST3-10, was isolated from sand sediment of a beach in Jeju, Korea, and was subjected to polyphasic taxonomic characterization. The organism produced circular, smooth, translucent, apricot-coloured colonies comprising coccoid- or rod-shaped cells. Phylogenetic analyses based on 16S rRNA gene sequences showed that the organism belonged to the family and consistently formed a distinct sub-branch outside the radiation of the genus . The organism showed 16S rRNA gene sequence similarity values of 98.2 % with respect to DSM 4725 and 98.1 % with respect to BC444. The type strains of the two species shared 98.2 % sequence similarity with respect to each other, whereas the levels of sequence similarity between the novel organism and the type strains of the less closely related neighbours, and , were in the range 96.2–96.9 %. The physiological, biochemical and chemotaxonomic data revealed that the novel organism can be readily differentiated from members of the genus and that it merits separate species status. On the basis of the phenotypic and genotypic evidence, strain KST3-10 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is KST3-10 (=NRRL B-24440=KCCM 42251).
