Kineococcus marinus sp. nov., isolated from marine sediment of the coast of Jeju, Korea.
A novel marine actinomycete, designated strain KST3-3(T), which was isolated from a sediment sample of the coast of Jeju, Korea, was subjected to a polyphasic taxonomic characterization. The organism was characterized morphologically by the formation of motile, coccoid cells. A phylogenetic analysis based on 16S rRNA gene sequence comparisons showed that the organism was related to the genera Kineosporia and Kineococcus, and members of the suborder Frankineae, and occupied the deepest branch outside a taxon encompassing members of the genus Kineococcus. The organism showed relatively low levels of 16S rRNA gene sequence similarity to members of the genera Kineococcus (93.0-93.4 %) and Kineosporia (93.1-93.8 %). The morphological and chemotaxonomic characteristics, albeit with a slightly higher level of sequence similarity to members of the genus Kineosporia, supported its classification within the genus Kineococcus. On the basis of the polyphasic data presented, it was evident that the organism should be assigned to a novel species of the genus Kineococcus, for which the name Kineococcus marinus sp. nov. is proposed. The type strain is strain KST3-3(T) (=KCCM 42250(T) = NRRL B-24439(T)).
