تقييم كفاءة استخدام الاشعة فوق البنفسجية و مستخلصي نباتي النعناع والالوفيرا في اختزال سم الفيومنزين B1 و نمو الفطر Fusarium Proliferatum المعزول من ثمار الموز المستوردة

الملخص EN

The study was conducted in the laboratories of Faculty of Agriculture/University of Kufa for the period from 24/12/2017 to 24/2/2019 to isolate and diagnose fungi associated with imported bananas fruits (Musa spp.

) in local markets.

The study included five varieties of bananas for different origins to identify the ability of isolated fungi and their production for mycotoxins, including F.

proliferatum.

and evaluation of the effectiveness ultraviolet radiation uv-c with a wavelength of 254 nm, for 15 minutes and different concentrations of peppermint and aloevera extracts were evaluated their effectiveness in reducing of Fumonisin B1.

The results showed the effect of UV-C and different concentrations of hot water extracts of peppermint and aloe vera to inhibit growth fungus F.

proliferatum on PSA medium, a significant effect of peppermint extract, as it showed an inhibition of the growth fungus F.

proliferatum.

Concentration 1.5% , with amounted to 75.52% compared to control treatment, in which the percentage of inhibition was 0.00% .

Ultraviolet light (UV-c) had a significant role in inhibiting the growth of the fungus.

Inhibition which increasing the duration of the fungus exposure to ultraviolet (UV) radiation, as the duration of 15 minutes gave the highest rate of inhibition amounting to 81.35 % compared to control treatment of 0.00 % .

The results also showed the high efficiency of ultraviolet radiation and peppermint extract at concentration of 1.5% in reducing toxicity of Fumonisin B1 and the protecting banana fruits from fungal infection, in addition to the possibility of prolonging the storage period.
