Abstract

A novel actinomycete, strain 04-5195, that produces amicoumacin B, which targets bone morphogenetic protein-2, was isolated from a soil sample collected in Jinan, Shandong Province, China. Strain 04-5195 had morphological, biochemical, physiological and chemotaxonomic properties that were consistent with its classification in the genus and it formed a phyletic line in the 16S rRNA gene tree. It was evident from the phylogenetic data that strain 04-5195 was most closely associated with N2-11. However, the two organisms were distinguishable from one another using DNA–DNA relatedness and phenotypic data. The isolate was readily differentiated from other related strains by a set of phenotypic properties and by its phylogenetic position. Therefore, it is proposed that the isolate represents a novel species in the genus , sp. nov.; the type strain is 04-5195 (=CGMCC 4.3508 =DSM 45048).
