However, the profiles of VOCs produced by both yeasts had been different, even though L479 primarily created acetic acid, 2-methylbutanoic acid and isobutyric acid, L793 synthesized various esters, alcohols and aromatic compounds, using the primary ones being 2-methyl-1-butanol and isoamyl alcohol.Toxins 2021, 13,7 of2.2. Influence of VOCs on Development Parameters of Aspergillus Flavus The effect of VOCs produced by the two yeast strains tested within this study by their antagonistic activity on development parameters of A. flavus was evaluated to be able to analyze their capacity to inhibit or manage A. flavus improvement. Table 2 shows the size of mycelia, lag phase before growth and development price of A. flavus within the presence and absence from the two antagonistic yeasts (L479 and L793) during a 21-day incubation period at 25 C. The mold in the absence in the yeasts grew from 13.55 0.55 mm at day 3 to 75.20 0.42 mm at day 21. A important reduction in growth (p 0.05) on all sampling days was observed when H. uvarum L793 was coinoculated using a. flavus. The presence of H. opuntiae L479 lowered A. flavus development (p 0.050) from day three to day 12 of incubation.Table two.
