Application of the concept of non-specific microorganisms-radionuclide interaction for development methods of radioactive waste water purification

Prof. Oleksandr Tashyrev (National Academy of Science of Ukraine)

17 July @ 11:00 - 13:30

The talk will tell about implementation of the theoretical concept for development of processes of radioactive waste water purification and bioremediation of radionuclide-contaminated environment using microorganisms and plants. The first part of the presentation will include analysis of selective accumulation of elements at organism and ecosystem levels in the context of Vernadsky biosphere theory as well as justification an idea that microorganisms are the most efficient bioaccumulating agents. Also, synergic effects of use of several types of organisms for radionuclide extraction will be considered. The second part will summarize concept outputs and discuss their application to overcome the key methodological problems of radioactive water purification. In this part detailed experimental results on microbial extraction of radionuclides from radioactive waste water will be given to demonstrate reliability and efficiency of established approach. The last part will summarize essential conditions for purification of liquid radioactive waste based on electrochemical approach and non-specific interaction (reduction and accumulation) of radionuclides with microorganisms. Finally, bioremediation strategies for radionuclide-contaminated environment and development of plant-microbial artificial ecosystems with the enhanced bioaccumulating capacity will be considered.
