| Abstract: | Summary Culture extracts produced by 107 fungi isolated from corn grains were assayed by thin layer chromatography for aflatoxin. Certain isolates ofAspergillus flavus, A. niger, A. parasiticus, A. ruber, A. wentii, Penicillium citrinum, andP. variabile produced aflatoxin.Penicillium frequentans andP. puberulum elaborated this toxin only in trace amounts. Bioassays of extracts from 4 of these fungi showed that only the extract fromA. parasiticus was highly toxic. |
