Poláková, Marianna ; Dvořáčková,, Helena (referee) ; Krčma, František (advisor)
Bachelor thesis is focused on the impact of plasma activated water on soil microorganisms. Reactive spieces of oxygen and nitrogen are present in plasma activated water, which are responsible for its biological and chemical properties. Thanks to its unique features, plasma activated water is used for therapeutic purpose or in agriculture. The theoretical part is concentrated on general information about soil, its properties and microorganisms found in it. Furthermore, it deals with basic information about plasma and sources used for its production. The last part presents the plasma activated water and its specific characteristics. Experimental part deals with the application of distilled water, plasma activated water and a mixture of distilled and plasma activated water on soil. In the first set of experiments, it was an application directly on the soil, the application to the soil extract was in the second set. Bacteria were inoculated on culture medium in concentrations 10-2, 10-4 and 10-6. The number of formed colonies was observed and then some microorganisms has been identified. Based on the results, it can be stated that plasma activated water had a positive effect on the microorganism colonies growth. However, the subject of further work will be to determine whether it is positive for pathogenic microorganisms or not.
