Cyclopiazonic acid and aflatoxins production by Aspergillus flavus isolated from Argentinian corn

Thirty-four isolates of Aspergillus flavus obtained from the main Argentinian corn production area were tested for their ability to produce both cyclopiazonic acid (CPA) on corn and on liquid media and aflatoxins on corn. Aflatoxins and CPA were quantified by comparison with standards. The last one...

Aflatoxins and CPA were quantified by comparison with standards. The last one was confirmed by mass spectrometry. All but one of the isolates produced CPA on liquid medium in a range between 3120 to 62500 μg/kg, 27/34 isolates produced CPA on corn at levels ranging from 833 to 10000 μg/kg and 5/34 isolates produced aflatoxin B1 in a range between 29 to 115 μg/kg. According to these findings, the percentage of Aspergillus flavus isolates with CPA production ability and their levels of CPA production were higher than the observed elsewhere. It was observed significant differences (p<0,01) between CPA production on corn (median: 1761 μg/Kg) and in liquid medium (median: 27950 μg/Kg).
