The process of accelerated deactivation of highly active water solutions of radioactive isotopes in growing microbiological MCT granules has been studied. We have observed sped up decay of the ¹³⁷Cs isotope in all experiments with MCT during 100 days. In the control experiment (flask with active water without MCT), the law of decay was "usual" and the life-time was about 30 years. The process was connected with transmutation of radioactive nuclei to non-radioactive isotopes during growth and metabolism of microorganisms. MCT ("microbial catalyst-transmutator") has included concentrated biomass of metabolically active microorganisms (microbe syntrophin associations), sources of microelements and gluing substances. The most sped up decay of ¹³⁷Cs (accelerated by 12 times!) was observed with the presence of additional Ca salt in active water. The process of effective experimental transmutation of stable ⁵⁵Mn isotope to rare Mössbauer ⁵⁷Fe isotope in MCT with heavy water presence is also presented and discussed.
