Regulation of photosynthetic activity of pigment-protein complexes in thylakoid membranes
KUTHANOVÁ, Eliška
The mechanisms of photoprotection have been examined in the secondary endosymbiotic algae Chromera velia and Rhodomonas salina. I applied biochemical, physiological, and spectroscopical methods to reveal the mechanism of nonphotochemical quenching (NPQ) in native cells and in isolated antenna proteins. The results were compared to the NPQ mechanism already described in higher plants and put to the context within the evolutionary frame of photoprotection.
Mechanism of photoprotection in photosynthetic proteins
KUTHANOVÁ, Eliška
Nonphotochemical quenching is an important protective mechanism of photosynthetic proteins against excessive irradiation. In this work, isolation of native light harvesting antennae from alga Chromera velia was optimized using methods of sucrose density centrifugation, isoelectric focusing, ion exchange chromatography and gel electrophoresis. Moreover, the ability of light harvesting antennae to trigger nonphotochemical quenching was studied in vivo and in vitro.
Occurence of organic pollutants in constructed wetlands
KUTHANOVÁ, Eliška
Constructed wetlands are wetlands designed to improve the quality of water. In this work, four representatives of typical organic pollutants in Constructed wetlands are studied : DEET, cotinine, coprostanol and galaxolide as the representatives of insecticide, alkaloid,faecal sterol and musk compound respectively. Moreover three different types of extraction techniques : aqueous two phase extraction (ATPE), liquid-liquid extraction (LLE) and stir bar sorptive extraction (SBSE) - are investigated with respect to the overall extraction yield regarding the above mentioned compounds.
