Multiple toxin production by an isolate of Aspergillus flavus

  • J. L. Richard
  • R. T. Gallagher


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.
