دراسة تأثير استعمال الأوزون في تثبيط نمو العفن Aspergillus و العفن Penicillium

الملخص EN

A study was conducted to determine the effectiveness of ozone and its impact on growth inhibition molds Aspergillus and Penicillium and determine the dose and time optimization to get this effect.

The results showed that the use of ozone gas dose 1 g for 60 minutes was enough to inhibit the growth of Conidia spore of the fungus Aspergillus and Pencillium suspended in distilled water sterilized and the conidia spore of penicillium suspended in whey by 100 %, while requests use the same dose of ozone increase the exposure time to 90 minutes to get the same percentage of inhibition 100 % for the growth of spores Conidia of the fungus Aspergillus suspended in whey while requests exposing Conidia spores fungus Pencillium suspended in whey to 60 minutes to get the same percentage of inhibition and this is due to the role of whey proteins and other materials in providing protection of Conidia spore, while the use of ozone gas At a dose 1.5 g for 60 minutes was enough to inhibit growth Conidia spores of Aspergillusand Pencillium suspended in distilled water as well as the case of the spores pending Conidia in whey.
