title: Toxicity of Aspergillus flavus cultures isolated from Egypt.
abstract: Aflatoxin produced by 61.14% of the Aspergillus flavus cultures, isolated from Egypt. A wide potential range for aflatoxins B and G groups was obvious among the isolates. The concentration of aflatoxin B, produced by toxigenic cultures, ranged from 1,500 to 81,000 p.p.b. (mug/kg substrate), corresponding to 1,900 to 184,000 p.p.b. for aflatoxin G. However, 7.59% of the isolates produced more than 50,000 p.p.b. of aflatoxins B + G.
