Abstract

Laboratory experiment was carried out to evaluate three kinds of media containers for aflatoxin B1 production on rice . One liter volume flasks , one kilogram silicon bag, and 25 Cm wide ,5Cm high Petri dish ,with three media weight , 50 , 150 and 250 gram / container at three moisture content , 18% , 20% , 22%. Results showed highly significant differences ( P< 0.01 ) in amount of aflatoxin B1 concentrations between treatments , and the Petri dish was superior among treatments followed by flask while silicon bag resulted in the least of aflatoxin production at 18% of moister content for all used weights . The results also showed adverse effects of increased weight and moisture content of culture media on fungal growth and inhibition of toxin production in all treatments .
