عنوان المقالة: ASSESSING THE EFFICACY OF CERTAIN NANO, NATURAL AND CHEMICAL MATERIALS IN FUNGAL INHIBITION AND AFB1 TOXIN REDUCTION OF ASPERGILLUS FLAVUS ISOLATED FROM PEANUT ON PDA MEDIA
This study was conducted in the efficiency of some nanomaterials (magnesium oxide), natural products (fish oil) and chemical (Phylex). Seed testing results revealed presence of different fungal genera, including Aspergillus, Penicillium, Rhizopus, Alternaria, Fusarium, Mucor and Cladosporium. In addition, A. flavus scored the highest sovereignty followed by A. niger and A. ochraceus in peanut samples at frequency rates 40, 12.28 and 10% respectively. The emergence rates before and after surface sterilization were 78.125-80.89, respectively. Results confirmed that 9 out of 15 isolates A. flavus isolates were capable to produce AFB1 when grown in rice medium. It was observed when adding MgO nanoparticles at concentrations of 1%, 2% and 3% concentrations resulted in fungal growth inhibition by 95% and 100%, respectively. Besides Phylex treatment could inhibit A. flavus growth by 100%, 100% and 74.8% when 0.03 and 0.02 and 0.01 concentrations were used, respectively. While fish oil treatment at concentrations of 2%, 4% and 6% inhibited fungal growth up to 80.4%, 100 % and 100% respectively.
