introduction:toxigenic fungi such as a. flavus grow widely in peanut and produce aflatoxins, a group of carcinogenic metabolites. aflatoxin produced in peanut differed from the genetic variety of plant. the high humidity and moderate temperatures in the subtropical caspian littoral of northern iran could increase the growth of a. flavus and the production of aflatoxin. the objectives of this st...
One hundred-thirty soil isolates of A. flavus were collected from commercial pistachio orchards in two main production regions including Rafsanjan (Kerman Province, south-eastern of Iran) and Damghan (Semnan Province, central north of Iran) and assayed for vegetative compatibility groups (VCGs). The sixteen and twenty VCGs were identified for 41 and 37 nit-mutant producing isolates of A. flavus...

Background: Aflatoxins (AFs) are the most prevalent carcinogenic mycotoxins, produced mainly by Aspergillus flavus and A. parasiticus. The general purpose of the present study was to use Dehydroacetic Acid (DHA) and Ozonated Water (OW) to control A. flavus growth and accumulation of Aflatoxin B1 (AFB1) in Iranian pistachios. Methods: Three treatment pistachio groups were separately immersed ...
