This diploma thesis deals with the applicability of thermal analysis in the influence of stress factors on microorganisms. The main aim of the presented work was to design and implement a series of experiments to thest the usability of advanced methods of thermal analysis in the characterization of microorganisms. Two bacterial strains were used as model organisms: Cupriavidus necator H16 and its mutant strain Cupriavidus necator PHB-4, which differs in the ability to produce polyhydroxyalkanoates. The basic technique used thermogravimetric analysis (TGA), which was optimized and applied in the study of water transport, behavior and determination of intracellular water content with respect to the influence of the presence of intracellular PHB granules. The results of this method were subsequently supported by TEM photos.
