An aflatoxin-producing isolate of Aspergillus fEauus wab found to be a conaisteiit producer of aflatoxin on all substrates which supported the growth of the mold. In competition with six other selected molds, this isolate was dominant except with one 5pecies of Peniczllium. Atlatoxin production was parallel to the extent of A . flavws growth whether effected by substrate or competition.

Three toxins were recovered from rice and wheat cultures of an isolate of Aspergillus flavus. The toxins were present simultaneously in the cultures after one or two weeks incubation and were identified as aflatoxin, cyclopiazonic acid and aflatrem, a recently identified indole-mevalonate metabolite
From the storerooms of individual households 150 samples of dried beans and 90 samples of stored maize were collected for mycological analyses. Two of 27 isolates of A . fluuus grown on malt extract agar (MEA) were found to produce the mycotoxin cyclopiazonic acid (25 -36 pg/g). Three of the A . ,fl
