Mycotoxins are toxic secondary metabolites secreted by filamentous fungi, mainly belonging to the genera Aspergillus, Fusarium and Penicillium, in food productions of plant origin. Contamination by mycotoxins causes significant economic losses. These molecules are also resistant to processing treatments such as cooking or roasting and can therefore be found in the entire food chain. About thirty of them are recognized for their harmful effects on human and animal health. The use of fungicides is currently the most used means to fight against the mycotoxic risk. However, in a context of sustainable development, alternatives based on biocontrol are to be developed. The objective of this work was to study a biological control method that could...
