Studies in the biochemistry of micro-organisms

Abstract

Spinulosin (3,6-dihydroxy-4-methoxy-2,5-tolu-quinone), previously reported as a metabolic product of Penicillium spinulosum, has now been isolated from cultures of a strain of A. fumigatus. This finding contrasts with the fact that a different strain of A. fumigatus gives fumigatin (3-hydroxy-4-methoxy-2,5-toluquinone).
