The thesis deals with methods for viability evaluation of the phytopathogenic bacterium Xanthomonas euvesicatoria after low-temperature plasma treatment. Low-temperature plasma produced by Gliding Arc experimental device was used for treatment of X. euvesicatoria. The viability of the bacterial cells was assessed using a scanning electron microscope (SEM) and by measuring of the fluorescence in the Smart-DART device using PrestoBlue chemical reagent. Methodology has been optimised for the sample preparation for the treatment by low temperature plasma and used for evaluation of applied methods. Lethal effect of gliding arc plasma to this gram-negative bacteria was verified by SEM which showed. There is significant structural changes on the cell surface. Viability assessment of X. euvesicatoria using Smart-DART device is a fast, time-saving and inexpensive evaluation of cell viability. The great advantage of this device is its ability to measure the fluorescence in real time. The disadvantage of this method is lower reliability in current stage of research.
