Biocontrol potential of native yeast strains against and aflatoxin production in pistachio.

is the main aflatoxin producer in food and feed and has wide ecological niches. Contamination of food products such as pistachio nuts and aflatoxin secretion directly affects food safety and international food product trades. Abilities of 13 yeast strains isolated from 200 soil and pistachio nut samples collected in Iranian orchards to reduce the growth of as well as aflatoxin production were assessed in dual culture, volatile and non-volatile compounds tests.
