Aflatoxin production in peanut varieties by Aspergillus flavus Link and Aspergillus parasiticus Speare.
Levels of aflatoxin produced in peanuts differed with the genetic variety of plant and with the species and strain of invading fungus. Possibilities for identifying groundnut varieties partially resistant to aflatoxin production are discussed.
متن کاملCharacterization of aflatoxigenic Aspergillus flavus and A. parasiticus strain isolates from animal feedstuffs in northeastern Iran
Aflatoxins are secondary toxic metabolites produced by some Aspergillus spp. particularly, Aspergillus flavus and A. parasiticus that contaminate food and feed. The objective of this study was to evaluate the contamination of feedstuffs with Aspergillus spp. and detect genes involved in the aflatoxin biosynthesis pathway of A. flavus and A. parasiticus isolates. A total of 110 cow feed samples ...
متن کاملمقایسهی رشد قارچ Aspergillus parasiticus و Aspergillus flavus در شرایط مختلف دما، رطوبت و pH
چکیده قارچ‌های Aspergillus parasiticusو Aspergillus flavusاز مهمترین عوامل آلودهکنندهی موادغذایی و دارای قابلیت تولید توکسینهای سرطانزا میباشند. آگاهی از شرایط بهینهی رشد، به کنترل و ممانعت از آلودگی و سمزایی این قارچ‌ها کمک می‌کند. این آزمایش به منظور بررسی تأثیر دما، pH و میزان رطوبتبذر بر رشد این دو گونه قارچ اجرا شد. تاثیر رطوبت بذر (در سطوح 15، 18، 21، 24، 27 و 30 درصد) و دما (...
متن کاملCharacterization and population analysis of the mating-type genes in Aspergillus flavus and Aspergillus parasiticus.
We characterize the mating-type genes in Aspergillus flavus,Aspergillus parasiticus and Petromyces alliaceus. A single MAT1-1 or MAT1-2 gene was detected in the genomes of A. flavus and A. parasiticus, which is consistent with a potential heterothallic organization of MAT genes in these species. In contrast, the only known, functionally homothallic species in Aspergillus section Flavi, P. allia...
متن کاملPossible implications of reciprocity between ethylene and aflatoxin biogenesis in Aspergillus flavus and Aspergillus parasiticus.
Aspergillus flavus and Aspergillus parasiticus produced ethylene during early growth. However, the onset of toxin biosynthesis was marked by the absence of ethylene evolution. 2-Chloroethyl phosphonic acid, an ethylene-generating compound, inhibited aflatoxin biosynthesis in vivo. The reciprocal relationship between the production of aflatoxin and ethylene by the organism may indicate the invol...
