AI Article Synopsis
- The essential oil (EO) was tested for antifungal and antiaflatoxigenic activity using vapor and liquid-phase contact methods, showing total mycelial growth reduction at concentrations of 20 μg/mL and 400 μg/mL, respectively.
- At a lower concentration of 10 μg/mL, the EO significantly decreased aflatoxin production by 97.0% and 56.4% in vapor and liquid-phase tests, respectively, alongside greater inhibition of specific fungal and aflatoxin-related genes.
- The EO also reduced aflatoxin levels in brown rice by 72.7% and in white rice by 18.0%, suggesting that vapor-phase application of
Article Abstract
The antifungal and antiaflatoxigenic activity of essential oil (EO) against was evaluated over a range of concentrations in vapor- and liquid-phase contact tests. Total reduction in mycelial growth in the vapor- and liquid-phase tests was detected at EO concentrations of 20 and 400 μg/mL, respectively. Treatment with 10 μg/mL EO reduced aflatoxin production by 97.0 and 56.4% in the vapor- and liquid-phase tests, respectively. Greater inhibition of the expression of both fungal development-related genes ( and ) and aflatoxin biosynthesis-related genes ( and ) was also observed in the vapor-phase test. A substantial reduction in aflatoxin production was also observed in brown rice (72.7%) and white rice (18.0%). Our results indicate that the way this EO contacts fungal cells significantly affects its antifungal activity and that EO in vapor phase might be a good strategy to control fungal contamination.
