Genotoxicity of aflatoxins and their precursors in human cells
(Elsevier Ireland, 2018-05)
Aflatoxins are found as food contaminant and some of them demonstrate a carcinogenic effect. The aflatoxins biosynthetic pathway involves 15 successive steps. The aim of this study was to compare the toxicity of aflatoxins ...
Present status and perspective on the future use of aflatoxin biocontrol products
(MDPI, 2020-04)
Aflatoxin contamination of important food and feed crops occurs frequently in warm tropical and subtropical regions. The contamination is caused mainly by Aspergillus flavus and A. parasiticus. Aflatoxin contamination ...
Characterization and competitive ability of non-aflatoxigenic Aspergillus flavus isolated from the maize agro-ecosystem in Argentina as potential aflatoxin biocontrol agents
(Elsevier Science, 2018-07)
Aspergillus flavus is an opportunistic pathogen and may produce aflatoxins in maize, one of the most important crops in Argentina. A promising strategy to reduce aflatoxin accumulation is the biological control based on ...
Quantification of aflatoxin M1 carry-over rate from feed to soft cheese
(Elsevier Inc, 2019-01)
From January to December 2016, samples of milk and feeds of dairy cattle were monthly collected. The concentration of mycotoxins in all matrices was determined using the enzymatic immunoassay technique. The average ...
Aflatoxins distribution in fractions derived from tofu production
(Taylor & Francis, 2019-10)
Tofu or bean curd is obtained from soybean seeds being a widespread food product in Asia. The commodity used for its production can be contaminated with aflatoxins, which are secondary metabolites synthetised by species ...
Fungal screening and aflatoxin production by Aspergillus section Flavi isolated from pre-harvest maize ears grown in two Argentine regions
(Elsevier, 2017-02)
Aflatoxin contamination in maize kernels grown in central Argentina has increased since 2008. Pre-harvest maize ear samples were collected during two growing seasons to determine prevalent fungal genera as well as aflatoxin ...
Non-aflatoxigenic Aspergillus flavus as potential biocontrol agents to reduce aflatoxin contamination in peanuts harvested in Northern Argentina
(Elsevier Science, 2016-08)
Biological control is one of the most promising strategies for preventing aflatoxin contamination in peanuts at field stage. A population of 46 native Aspergillus flavus nonaflatoxin producers were analysed based on ...
Aflatoxins and Saccharomyces cerevisiae: Yeast modulates the intestinal effect of aflatoxins, while aflatoxin B1 influences yeast ultrastructure
(Wageningen Academic Publishers, 2017-05)
The gastrointestinal tract (GIT) is the main site where absorption of food components takes place and the first system coming into contact with mycotoxins of dietary origin. The aim of this work was to study the effect of ...
Microbiological quality, fungal diversity and aflatoxins contamination in carob flour (Prosopis flexuosa)
(Elsevier, 2020)
Carob flour is obtained from pods of some species of Prosopis, leguminous trees that abound in many desert habitats worldwide. Currently, this product is available in healthy food stores in several countries, including ...
Aflatoxins, deoxynivalenol and zearalenone in maize straw harvested in Tepatitlan, JaliscoAflatoxinas, deoxinivalenol y zearalenona en rastrojo de maíz cosechado en Tepatitlán, Jalisco
(Universidad Autónoma de Nayarit, 2016-05)
There are few reports on the contamination of total aflatoxins (AFs), AFB1, deoxynivalenol (DON) and zearelenone (ZEA) in maize straw harvested in Mexico; hence, the aim of this study was to determine the concentration of ...
