Abstract

The formation of aflatoxicols (AFL) by 9 strains of Aspergillus flavus isolated from moldy corn, which was naturally contaminated with both aflatoxins (AF) and AFL, and by 2 strains of A. parasiticus from buckwheat flour was investigated.
All of the AF-producing A. flavus and A. parasiticus strains showed activity to form both AF and AFL. The accumulation of AF and AFL in three substrata (corn grits, polished rice and peanuts) by an AF-producing strain of A. flavus was investigated. In each substratum, the largest amount of AF was detected at 6 to 10 days' incubation, and the amounts of both AFL A and B rapidly increased thereafter.
