SUMMARY— The effects of controlled atmosphere (CA) (10% CO 2 , 1.8% O 2 and 88.2% N 2 and air were noted on the growth of aflatoxin production of Aspergillus flavus incubated at several temperatures on 2 substrates. In liquid medium, the mold grew well and produced toxin in both air and CA at room temperature. At 60°F, growth and toxin were substantial in air but minimal in CA. At temperatures of 54°F and below. toxin was inhibited; growth was minimal in air and inhibited in CA. Cracked corn of 16.6, 18.8, 23.6 and 31.2% moisture content (dry basis) also was studied. At 31.2% moisture and 60°F, growth was reduced in CA to a greater extent than in air. whereas sporulation and toxin in CA showed a longer lag period at both 84 and 60°F.
