Actinomadura namibiensis sp. nov.

Strain HAG 010767(T) was isolated from desert soil from Namibia during a screening programme. On the basis of analysis of 16S rDNA, the principal amino acid of the peptidoglycan, cell-wall sugars, fatty acids and polar lipids, it was possible to identify this strain as a member of the genus Actinomadura. Although DNA-DNA reassociation experiments revealed 72% DNA similarity between strain HAG 010767(T) and Actinomadura kijaniata DSM 43764(T), significant differences in the colour of the mycelium and physiological properties indicate that strain HAG 010767(T) represents a novel species of this genus, for which the name Actinomadura namibiensis sp. nov. is proposed. The type strain is strain HAG 010767(T) (= DSM 44197(T) = NRRL B-24153(T)).
