Zinc concentrations strongly influence aflatoxin accumulation in laboratory media and in food and feed crops. The presence of zinc stimulates aflatoxin production, and the absence of zinc impedes toxin production. Initial studies that suggested a link between zinc and aflatoxin biosynthesis were presented in the 1970s. In the present study, we utilized two zinc chelators, N,N,N',N'-tetrakis (2-...

Peanut pods are easily infected by aflatoxin-producing Aspergillus sp.ecies from field soil. To assess the aflatoxin-producing Aspergillus sp. in different peanut field soils, 344 aflatoxin-producing Aspergillus strains were isolated from 600 soil samples of four agroecological zones in China (the Southeast coastal zone (SEC), the Yangtze River zone (YZR), the Yellow River zone (YR) and the Nor...

Aflatoxins are the most serious problem in production and export of pistachio of Iran. They are amongst the most toxic mycotoxins and are produced predominantly by Aspergillus flavus and A. parasiticus. Pistachio is susceptible to invasion by aflatoxigenic Aspergillus species and subsequent production of aflatoxins, during preharvesting, processing, transportation or storage. Various methods ha...
