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 کاملInhibition of Aspergillus flavus colonization and aflatoxin (AfB1) in peanut by methyleugenol.
Methyleugenol is naturally occurring substance in oils and fruits and in various foods as flavoring agent. Effect of this methyleugenol in inhibiting A. flavus colonization and aflatoxin production on peanut pods and kernels has been studied. Spray of methyleugenol (0.5%) on peanut pods and kernels checked the colonization of A. flavus and aflatoxin synthesis. This chemical can be used as both ...
متن کاملBiocontrol of Aspergillus Flavus and Aflatoxin B1 Production in Corn
The potent mycotoxin aflatoxin B1 is a secondary metabolite of Aspergillus fungi that grow, on a variety of food and feed commodities at any stage during growth, harvest, storage and transportation. The occurrence of aflatoxin contamination is global, with severe problems especially prevalent in developing countries. In present study, corn samples were contaminated with aflatoxin B1 in the conc...
متن کاملAspergillus flavus infection and aflatoxin production in fig fruits.
Immature fig fruits did not support colonization and aflatoxin production by Aspergillus flavus Lk. but became susceptible when ripe. While sun-drying on the tree, fruits were particularly vulnerable to fungal infection and colonization. Aflatoxin accumulation equaled levels frequently reported for such seeds as peanuts and cereal grains.
متن کاملPositive correlation exists between glutathione S-transferase activity and aflatoxin formation in Aspergillus flavus.
The presence of glutathione (GSH) S-transferase activity, using 1-chloro-2, 4-dinitrobenzene (CDNB) as a substrate, has been established in the cytosolic fraction of the toxigenic (aflatoxin producing) and nontoxigenic strains of Aspergillus flavus. Significant differences in the GSH S-transferase activity were observed between the toxigenic and non-toxigenic strains. A positive correlation has...
