The แหล่งกำเนิดstrain
has been modified by γ-irradiation mutagenesis, resulting in the deletion of gene clusters required for
the synthesis of the mycotoxins cyclopiazonic acid (cpa) and aflatoxin (afl). UV irradiation
mutagenesis resulted in a reduced potential (15 % of the original) to produce kojic acid. None of these
three species-specific mycotoxins (CPA, NPA and KA) were detected in the food enzyme (Table 1) by
mass spectrometry (LC-MS/MS).
