[The "in vitro" effect of aflatoxin B1 on the development and toxinogenesis of "Aspergillus" gr. "glavus" (author's transl)].
After culture of Aspergillus flavus in synthetic medium supplemented with aflatoxin B1, the level of mycotoxin decreases rapidly during the course of two or three days. Later, in the case of highly toxinogenic strains, a reduction in the production of aflatoxins is observed; whereas, conversely, in the case of low toxinogenesis are obtained in the presence of high levels of the mycotoxin. With all strains of A. flavus, the presence of aflatoxin B1 in the medium at the time of inoculation, moderately limits the growth of mycelium but it has a little effect on the conidial sporulation.
