Four hundred and twenty nitrate non-utilizin...

out of fifty-two iranian nonaflatoxigenic strains of aspergillus flavus, which were collected from various substrates (soil and kernel) and sources (peanut, corn and pistachio), fifteen representatives were selected according to their different geographical origins (six provinces: guilan and golestan, ardebil, fars, kerman and semnan) and vegetative compatibility groups (vcgs, ir1 to ir15) for ...
