Characterization of Iranian Nonaflatoxigenic Strains of Aspergillus flavus Based on Microsatellite-primed PCR
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 ...

متن کاملInteraction of strains of non - toxigenic Aspergillus flavus with Aspergillus parasiticus on aflatoxin production
Aflatoxins production is affected by abiotic, biotic and genetic parameters. Eugenesic and dysgenetic condition for aflatoxinogenesis are relatively well studied, such as: the influence of temperature, pH, Aw, Oxigen tension, osmotic pression, organic and inorganic nutrients, substance with fungistatic effects: however there are relatively few knowledge about endogenous regulator mechanisms, th...
متن کاملPurification and characterization of mannitol dehydrogenase from Aspergillus parasiticus.
Mannitol dehydrogenase, NADP specific (EC 1.1.1.138), was purified from mycelium of Aspergillus parasiticus (1-11-105 Whl). The enzyme had a molecular weight of 1.4 X 10(5) and was composed of four subunits of apparently equal size. The substrate specificity was limited to D-mannitol, D-glucitol, D-arabinitol, 1-deoxy-D-mannitol, and 1-deoxy-D-glucitol. Zinc ion was a powerful inhibitor of the ...
