Fungi isolated from soils adjacent to olive trees in Nineveh Governorate
Abstract
In order to investigate the inhibitory effects of alcoholic extracts on the vitality, effectiveness, and presence of fungus associated with olive trees, the study entailed the manufacture of alcoholic extracts from olive leaves that were acquired from the gardens of the University of Mosul. We tested the inhibitory effect of the olive leaf extract on the following fungal species isolated from soil near the olive trees ; Aspergillus caespitosus , A. cremus , A. flavus , A. parasiticus , A. niger , Fus a rium incarnatum , Trichoderma harzianum , T. longibrachiatum , and Pleospora rosae are some of the fungi that are i n cluded in this group.The strategy consisted of mixing the alcoholic extract with quantities of PDA culture media consisting of five, ten, twenty, and thirty milligrams per milliliter. This was done in order to demonstrate an inhibitory impact on the development of the fungi mentioned above. One hundred percent inhibition was found for T. longibrachiatum , T. harzi a num , Pleospora rosae , and A. niger at doses of thirty milligrams per milliliter, while a concentration of twenty milligrams per milliliter likewise produced one hundred percent inhibition. There was no discernible effect seen from the presence of A. cremeus at doses of 10 and 30 mg/mL, respectively. As a result, these extracts have the potential to be used as sterilizers (antiseptics) or as preservatives for utilization in the food industry, as well as in the cosmetics industry. In the event of an illness, they can also be used as a lotion that is applied externally. It is possible to effectively grow olive trees in regions that are impacted by pollution, such as hospitals, schools, and other environments that contain comparable conditions.References
