  • Title: Effect of phytate on aflatoxin formation by Aspergillus parasiticus and Aspergillus flavus in synthetic media.
    Author: Ehrlich K, Ciegler A.
    Journal: Mycopathologia; 1984 Aug 30; 87(1-2):99-103. PubMed ID: 6436710.
    Abstract:
    The effect of phytate on the production of aflatoxins by Aspergillus parasiticus and Aspergillus flavus grown on synthetic media was examined. In the absence of pH control (initial pH 4.5-6.5) for A. parasiticus, phytate (14.3 mM) caused a six-fold decrease in aflatoxins in the medium and a ten-fold decrease in those retained by the mycelia. When the initial pH of the medium was adjusted to 4.5 no effect on aflatoxin production was observed. With A. flavus or A. parasiticus grown on media with a higher initial pH value (6 to 7), the presence of phytate in the media caused an increase in aflatoxin production. These results are inconsistent with previous studies which indicated that phytate depresses aflatoxin production by rendering zinc, a necessary co-factor for aflatoxin biosynthesis, unavailable to the mold.
