Abstract

A novel strain, 219820, whose metabolites were found to be active against tumour cells, was isolated and characterized. The isolate belonged to the genus and had white to grey aerial mycelium and long chains of smooth spores in the aerial mycelium. A phylogenetic tree based on 16S rRNA gene sequences showed that strain 219820 had highest similarity to members of the genus and was most closely, albeit loosely, associated with NBRC 15401 (98.624 % similarity), NBRC 12890 (98.565 %) and NBRC 13065 (98.564 %). However, DNA–DNA relatedness and phenotypic data readily distinguished strain 219820 from these phylogenetically related type strains. It is evident from the combination of genotypic and phenotypic data that strain 219820 represents a novel species of the genus , for which the name sp. nov. is proposed; the type strain is 219820 ( = CGMCC 4.5626  = DSM 42014).
