Ph.D. dissertation discussion

The Department of Life Sciences at the College of Education for Pure Sciences at the University of Karbala discussed a Ph.D. thesis entitled (The taxonomic study of the inhibitory effectiveness of extracts of some plants belonging to different families and the evaluation of nano-extracts of them and of Saccharomyces boulardii against the toxin-producing Fusarium spp) by the student (Hadeel Amory Abd Ali Al-Amiri) and under the supervision of ( Prof. Dr. Nibal Amtair Al-Karawi), (Professor Dr. Suad Waheed Kazem).
The thesis aimed to use a safe and environmentally friendly alternative method to protect grains from fungi, and at the same time investigate the effectiveness of nanoparticles manufactured from extracts of some plants and Saccharomyces boulardii.
The thesis showed that yellow maize grains in Karbala were infected with many fungi, including Fusarium, and new isolates were recorded for the first time in Iraq from Fusarium, which was confirmed by molecular diagnosis. S. boulardii yeast extract and silver nanoparticles showed high inhibitory efficiency against fumonisin-producing species in the laboratory.
The thesis also recommended testing the ability of isolated Fusarium species to produce other mycotoxins such as DON, making biological preparations from rosemary extracts and making them a basic material in the animal diet for its high effectiveness against fungi and other germs, and evaluating the effectiveness of S. boulardii yeast extract in the manufacture of other nanomaterials. such as gold, zinc, copper, and others. The student got a very good grade.
