Nocardia jinanensis sp. nov., an amicoumacin B-producing actinomycete.
A novel actinomycete, strain 04-5195(T), 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(T) had morphological, biochemical, physiological and chemotaxonomic properties that were consistent with its classification in the genus Nocardia and it formed a phyletic line in the Nocardia 16S rRNA gene tree. It was evident from the phylogenetic data that strain 04-5195(T) was most closely associated with Nocardia speluncae N2-11(T). However, the two organisms were distinguishable from one another using DNA-DNA relatedness and phenotypic data. The isolate was readily differentiated from other related Nocardia 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 Nocardia, Nocardia jinanensis sp. nov.; the type strain is 04-5195(T) (=CGMCC 4.3508(T) =DSM 45048(T)).
