Lignite degradation in soil environment
 Vybíralová, Natálie ; Salaš, Petr (referee) ; Pekař, Miloslav (advisor)
This Master‘s thesis deals with the topic of coal and, more precisely South Moravian lignite. Lignite was degraded by using biological and chemical methods, which included oxidation of lignite with hydrogen peroxide. Special attention was paid to the degradation of lignite in the soil environment, where the simulation of natural fields conditions took place for 6 months. Furthermore, a simulation of root exudates was carried out using organic acids, which occur naturally in the soil environment and directly affect life in the soil and around the roots of the plant. Lignite degradation was also performed using a cultured bacterial solution and then using a commercially available horticultural products to increase the activity of soil microorganisms and promote growth.
