Actinomadura flavalba sp. nov., an endophytic actinomycete isolated from leaves of Maytenus austroyunnanensis.
An actinomycete strain, designated YIM 61435(T), was isolated from leaves of Maytenus austroyunnanensis collected from a tropical rainforest in Xishuangbanna, Yunnan Province, south-west China. The isolate produced aerial mycelium with long, curved to hooked spore chains. The chemotaxonomic characteristics of the isolate were consistent with its assignment to the genus Actinomadura. Phylogenetic analysis using 16S rRNA gene sequences also indicated that this strain should be classified in the genus Actinomadura; however, it could be separated clearly from its closest neighbour, Actinomadura atramentaria DSM 43919(T). Furthermore, a combination of DNA-DNA hybridization results and significant differences in morphological and physiological characteristics indicate that strain YIM 61435(T) represents a novel species of the genus Actinomadura, for which the name Actinomadura flavalba sp. nov. is proposed. The type strain is YIM 61435(T) (=DSM 45200(T) =CCTCC AA 208017(T)).
