21. Biotechnological treatment of chlorophenol-contaminated water
Abstract : Widespread presence of toxic and persistent pollutants in the environment, even at low concentrations, causes risks of adverse effects to human health and the ecosystem. Biological methods for treatment of water streams and removal of persistent pollutants are of great interest due to their simplicity, low cost, and mild operational conditions without harmful by-products.

22. Hierarchical responses to organic contaminants in aquatic ecotoxicological bioassays: from microcystins to biodegradation
Abstract : In this thesis I explore the ecotoxicological responses of aquatic organisms at different hierarchical levels to organic contaminants by means of bioassays. The bioassays use novel endpoints or approaches to elucidate the effects of exposure to contaminants and attempt to give mechanistic explanations that could be used to interpret effects at higher hierarchical scales.

23. 4-chlorophenol biodegradation by Arthrobacter chlorophenolicus A6
Abstract : A microorganism was isolated which could grow on unusually high concentrations of the toxic pollutant 4-chlorophenol. Taxonomic studies showed that the microorganism constituted a novel species within the genus Arthrobacter and it was named Arthrobacter chlorophenolicus A6. A. READ MORE

25. Investigation of degradation of toxic substances in fungal cultures by mass spectrometric techniques
Abstract : Micropollutants in water are biological or chemical contaminants that are present in ground and surface waters in trace quantities. They are a result of human activity and include pharmaceutically active compounds (PhACs) and endocrine disrupting compounds (EDCs). READ MORE
