Field evaluation of maize genotypes for resistance to pre-harvest Aspergillus ear rot and aflatoxin contamination under natural inoculation in Eastern and Northern Tanzania [PDF]

Frontiers in Plant Science
Maize, a staple for billions of people, is highly vulnerable to aflatoxin contamination caused by Aspergillus flavus. Aflatoxins pose serious threats and risks to food safety, public health, and trade.

Low-dose ethanol increases aflatoxin production due to the adh1-dependent incorporation of ethanol into aflatoxin biosynthesis

iScience, 2023
Summary: Aflatoxins are toxic secondary metabolites produced by some aspergilli, including Aspergillus flavus. Recently, ethanol has attracted attention as an agent for the control of aflatoxin contamination.

Effect of non-aflatoxigenic strains of Aspergillus flavus on aflatoxin contamination of pre-harvest peanuts in fields in China

Oil Crop Science, 2021
Aflatoxin contamination of peanuts is one of the most concerns in peanut production in China. Applying non-aflatoxigenic Aspergillus flavus strains, based on competitive exclusion, has been proved to be a promising strategy to reduce aflatoxin ...

Detection of Aflatoxins B1 in Maize Grains Using Fluorescence Resonance Energy Transfer

Applied Sciences, 2020
Aflatoxins are secondary metabolites of Aspergillus flavus and Aspergillus parasiticus. These fungal species are the most dangerous and common toxin group causing food contamination. Aflatoxin has high toxicity and can cause cancer to humans and animals.

Determination of the Aflatoxins [PDF]

Nature, 1964
Top of pageAbstract WE report a new chemical method for determining the aflatoxins and, in particular, aflatoxin B1. Previous methods have depended on the measurement of fluorescence1,2 and are subject to certain errors, for example, quenching by impurities.
