study on growth inhibition of aspergillus flavus and aflatoxin b1 reduction in pistachio by trichoderma strains
in this investigation the effect of trichoderma isolates in inhibition of aspergillus flavus growth and reducing of aflatoxin b1 (afb1) was studied in culture media and pistachio nuts. among trichoderma isolates, t1, t3, t4 and t17 isolates showed significant impact on inhibiting of a. flavus r5growth. t3 and t4 isolates were the most effective isolates, which caused 84.40% and 77.88% reduction...
متن کاملImpacts of Dehydroacetic Acid and Ozonated Water on Aspergillus flavus Colonization and Aflatoxin B1 Accumulation in Iranian Pistachio
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 ...
متن کاملthe effect of testa on reduction of aspergillus flavus growth and aflatoxin b1 production in pistachio kernels of different cultivars
abstract in order to evaluate the effect of testa on reduction of fungal growth and aflatoxin b1 producthon, ten cultivars of pistachio were collected from different parts of pistachio belt i-e rafsanjan, damghan and ghazvin of iran. a section of testa and one mm of endosperm were scraped. 20 gr. of wounded kernels and 20 gr. of unwounded kernels were surface sterilized and then placed in petri...
متن کاملEffect of Irrigation Systems on the Contamination of Aspergillus flavus and Aflatoxin Production in Shahpasand Pistachio Cultivar
Aflatoxins are secondary metabolites produced by Aspergillus flavus, A. parasiticus, A. tamari, A. bombycis and A. nomius species. Relative humidity (RH) is one of the most important parameters influencing the development of aflatoxins in pistachio orchards by Aspergillus species. The type of irrigation system affects density and frequency of the Aspergillus species in the soil. In the current ...
متن کاملEvaluation of Contamination of Aspergillus flavus and Aflatoxin Production in Pistachio Cultivars and Investigation of a Chemical Controlling Method
In order to study the contamination of Aspergillus flavus and aflatoxin production in pistachio cultivars in the Semnan province, eight cultivars of pistachio were collected from major pistachio growing areas. Using the serial dilution method, ground pistachio kernels were inoculated on plates containing AFPA medium and incubated at 28° C. This experiment was performed using three replications ...
