| Abstract: | The ability of four strains of Aspergillus parasiticus (IMI 301,001) and two strains of Aspergillus flavus (IMI 300,998) to produce aflatoxins on Nigerian groundnuts under varying conditions of temperature was studied. While all the A. parasiticus strains produced the four major aflatoxins (B1, B2, G1, G2), only aflatoxin B1, and B2 were produced by the A. flavus strains used. The optimum temperature for aflatoxin production by both the fungal species was 30 degrees C with no toxin production at 10 degrees C. |
