Originální abstrakt

Bacteria developed various strategies to cope with stress conditions including UV irradiation. Polyhydroxyalkanoates (PHA) are polyesters accumulated in form of intracellular granules by numerous bacteria primarily as storage compounds, nevertheless, we investigated that PHA granules are not used only as carbon and energy storage but bacteria can use this compound also as UV-protectant. . Mechanisms of protective effect of PHA granules were determined by different spectroscopic approaches such as turbidity measurement, absorption spectrophotometry with integration sphere , nephelometry and continuous fluorescence microphotolysis. Generally, protective mechanisms of PHA granules is predominantly based on very effective scattering of UV radiation with wavelength of about 250 – 290 nm which protect photo-sensitive molecules, especially DNA, from their damage
