The effect of inorganic salts and some biologically important compounds on the incorporation of 1-14C acetate into aflatoxins by resting mycelia of Aspergillus parasiticus.

Zn++, Mg++, and Mn++ ions at certain concentrations, stimulated the incorporation of [1-14C] acetate-into aflatoxins by resting mycelia of Aspergillus parasiticus suspended in tris-HCl buffer of pH 7.2. Ba++ gave consistant stimulation over a wide range of concentrations. Ethanol markedly inhibited the incorporation. Of the tricarboxylic acid cycle intermediates, citric acid gave the maximum stimulation.
