[Sorption capacity of microbial biomass with respect to various radionuclides]

Biosorption capacity of different microorganisms to uptake 90Sr, 137Cs and 239Pu radionuclides from aqueous solution was investigated. Distribution coefficients of the above-mentioned radionuclides were determined as well as their dependence upon sorption conditions and pretreatment of microbial biomass. The possibility to use of the biomass of some microbial strains for recovery Sr, Cs, Pu from ultra-dilute solutions was demonstrated.
