The potential of sodium bicarbonate to inhibit growth of and aflatoxin synthesis by A. parasiticus was examined in Czapek's agar (CA), a medium in which fluorescence under UV light indicates aflatoxin production. Incorporation of sodium bicarbonate (SB) into CA at 0.011, 0.022, and 0.033 mol% reduced cell viability 63-, 103-, and >107-fold, respectively. Colonies resulting from surviving cells did not fluoresce under UV light, but thin-layer chromatography analysis of culture extracts detected aflatoxins. Potassium bicarbonate (KB) at 0.011 and 0.022 mol% produced inhibitory effects similar to those of SB, but NaCl and silica had no effect. After 7
