Inhibition of T-2 toxin production on high-moisture corn kernels by modified atmospheres
The fungus Fusarium sporotrichioides, capable of producing T-2 toxin (T-2), was grown on irradiated corn kernels remoistened to 22% and kept in atmospheres of different CO/sub 2/-O/sub 2/ combinations. The production of T-2 was totally inhibited under 60% CO/sub 2/-20% O/sub 2/, whereas only trace amounts were detected when the gas combination was 40% CO/sub 2/-5% O/sub 2/. Under all other combinations tested, the amount of T-2 produced was reduced by 25 to 50% as compared with the control. Fungal growth was not inhibited by any of the gas mixtures examined, and the growth rate (measured by direct plating, dilution method, and CO/sub 2/ production) was almost identical to that in grains kept under air. It is concluded that although F. sporotrichioides is tolerant to high CO/sub 2/ levels, T-2 formation on corn can be inhibited by CO/sub 2/ concentrations less than that required to inhibit fungal growth.
