- In conducted experiments the decrease in the concentration of radioactive reactor Cs137 isotope by 23% (average value ) and up to 40-70% (in the most optimal bioreactors) during 7-10 days was observed due to its transmutation into a stable isotope of barium
- For further stages (up to 100%) of Cs137 isotope transmutation it is necessary to make the operational changes to the composition of the nutrient medium during transmutation.
- The presented results show perspectives and effectiveness of radioactive Cs137 isotope deactivation and radioactive water purification during controlled growth of microbiological syntrophic association for industrial and environmental applications (e.g. for accelerated deactivation of radioactive water in Fukushima area).
- The results of an independent examination confirmed the correctness of our previous results on the deactivation of radioactive isotopes, previously conducted at the “Shelter” object in Chernobyl
