[In vitro toxigenesis of Aspergillus fumigatus strain. Production of fumitoxins].
A new class of mycotoxins has been characterized from a strain of Aspergillus fumigatus: the fumitoxins A, B, C and D. The in vitro production of these metabolites is studied. Fumitoxins are common in cultures extracts of most strains of A. fumigatus. They are not detected from A. fischeri. Variations of the levels of these products during the incubation of cultures, and also by using different media, are noted. At all events, the toxicity of crude extracts of the mould, for the chick embryo, is equal to the one of the fumitoxins.
