Toxicity of mycotoxins produced by four Alternaria species toArtemia salina larvae.

22 isolates ofAlternaria alternata, A raphani, A consortiale, andA chartarum were examined for the production of alternariol (AOH), alternariol methyl ether (AME), altenuene (ALT), altertoxin I (ATX I), and tenuazonic acid (TA) on wheat grain and for toxicity of culture extracts toArtemia salina larvae. The total amount of 5 toxins produced under laboratory conditions ranged from 5 mg/kg to 11.112mg/kg. The toxic extracts showed EC50 values in the range of 3.3 to 144.5 mg/mL. There was no correlation between toxicity of extracts toArtemia salina and the amount of mentioned mycotoxins in culture.
