| Résumé : |
Aflatoxins, fungal toxins primarily produced by Aspergillus species, pose a significant public health concern due to their acute toxicity and carcinogenic potential. In this study, twenty aflatoxigenic Aspergillus strains belonging to the Flavi section, all isolated from maize intended for dairy cow feed in Algeria, were selected as biological models. The antifungal activity of a marine alga extract (Cystoseira compressa) at a concentration of 5 g/ml and zinc oxide nanoparticles (ZnO-NPs, 5 µg/ml) synthesized from this extract was evaluated in vitro. The results revealed a potent inhibition of fungal growth by ZnO-NPs, markedly higher than that obtained with the algal extract alone, thus suggesting a consequent inhibition of aflatoxin production. These findings highlight the potential of ZnO nanoparticles derived from algal extracts as an innovative and effective alternative to limit the contamination by aflatoxigenic fungi and their toxins. |
