Transformation of sterigmatocystin and O-methylsterigmatocystin (two metabolic aflatoxin precursors) to aflatoxins by aflatoxigenic and nonaflatoxigenic field isolates of Aspergillus flavus was studied. The 24 nonaflatoxigenic isolates investigated failed to transform both precursors. Among the 8 aflatoxin-producing isolated used, 7 transformed both precursors whereas the remaining failed to transform both. According to these results, the usefulness of the measurement of enzymatic activities related to aflatoxin production in understanding the true status of conflictive field isolates is discussed
