Studies in the biochemistry of micro-organisms

Abstract

THE following metabolic products, present in the metabolism solution of Penicillium griseo-fulvum Dierckx when this mould is grown under different cultural conditions and on different culture solutions, have been isolated in this laboratory: 6-hydroxy-2-methylbenzoic acid [Anslow & Raistrick, 1931], 2:5-dihydroxybenzoic acid (gentisic acid), fumaric acid and mannitol The purpose of the present communication is to record observations on a hitherto undescribed chlorine-containing metabolic product of P. griseo-fulvum which has been isolated from the mycelium of this mould and for which the name griseofulvin is proposed.
