摘要：

The effects of chloroperoxidase [EC 1.1.1.10] and hydrogen peroxide on the viabilities of quiescent and germinating conidiospores of an aflatoxigenic fungus, Aspergillus flavus, were determined. Hydrogen peroxide was found moderately lethal and chloroperoxidase produced a 30-fold increase in the lethality of hydrogen peroxide to germinating conidia, which were 75-fold more susceptible to chloroperoxidase than were quiescent conidia. According to infrared examinations of fungal corpses, mortality occurred by oxidation rather than peroxidative chlorination.
