Abstract:
The D-values of conidia of aflatoxigenic Aspergillus flavus and Aspergillus parasiticus exposed to 1.74 ppm. ozone in 1 mM potassium phosphate buffer (pH 7.0 and 5.5) at 25 degrees C were determined. D-values of A. flavus conidia were 1.72 and 1.54 min at pH 5.5 and 7.0, respectively; D-values of A. parasiticus were 2.08 and 1.71 min, respectively. None of these D-values was significantly (P < or = 0.05) different from each other.
