Abstract

An actinomycete with blue substrate mycelium was isolated from a soil sample in Cape Town, South Africa, and designated strain PK-Blue. The colour of the substrate mycelium was not sensitive to changes in pH. The organism produced hairy spores in -type spore chains. Chemical taxonomy indicated that it belonged to the genus . Strain PK-Blue produced no diffusible pigments other than melanin, grew at 45 °C, did not degrade adenine and exhibited no antibacterial activity against , or . Analysis of its 16S rRNA gene sequence and the results of physiological tests showed that strain PK-Blue (=DSM 41797=ATCC BAA-411) represents the type strain of a novel species of , for which the name sp. nov. is proposed.
