Aspergillus section Flavi and aflatoxins in Algerian wheat and derived products.
Wheat and its derivatives are a very important staple food for North African populations. The aim of this study was to analyze populations of Aspergillus section Flavi from local wheat based on aflatoxins (AFs), cyclopiazonic acid (CPA) and sclerotia production, and also to evaluate AFs-contaminated wheat collected from two different climatic regions in Algeria. A total of 108 samples of wheat ...
متن کاملContamination of Stored Pistachios to Aspergillus Section Flavi and Aflatoxins
Background: Contamination of stored pistachio nuts to Aspergillus section Flavi and aflatoxins (AFs) as well as effective parameters on fungal growth and AF production during storage was assayed. Methods: Twenty one pistachio nut samples were taken from some warehouse of Damghan county. Different parameters of storage, including temperature, relative humidity, and pest infestation were recorded...
متن کاملStudies on Aspergillus Section Flavi from Peanut in Iran
During 2010 and 2011, Aspergillus species from section Flavi were isolated from rhizosphere in main peanut-growing region of Iran, Astaneh-e Ashrafiyeh, Guilan Province (northern Iran). The soil samples were taken from fruiting zone of peanuts in 3 districts and 10 locations, during the pod-filling period. The populations of Aspergillus section Flavi showed significant differences in cfu g-1 am...
متن کاملEvaluating Aflatoxin Gene Expression in Aspergillus Section Flavi.
The determination of aflatoxin production ability and differentiation of aflatoxigenic strains can be assessed by monitoring the expression of one or several key genes using reverse transcription polymerase chain reaction (RT-PCR). We herein describe the methods for RNA induction, extraction, and quality determination, and the RT-PCR conditions used to evaluate the ability of a given Aspergillu...
متن کاملImpact of Aspergillus section Flavi community structure on the development of lethal levels of aflatoxins in Kenyan maize (Zea mays).
AIMS To evaluate the potential role of fungal community structure in predisposing Kenyan maize to severe aflatoxin contamination by contrasting aflatoxin-producing fungi resident in the region with repeated outbreaks of lethal aflatoxicosis to those in regions without a history of aflatoxicosis. METHODS AND RESULTS Fungi belonging to Aspergillus section Flavi were isolated from maize samples ...
