Popis:	Using different algea types the bioaccumulation of UO2 2+ and Th4+ ions from experimental residual wastes of nuclear facilities was investivated. The retaining degree of these ions on microbiological sorbents decreases as: Scenedesmus quadricauda > Porphyridium cruentum > Spirulina platensis > Calothrix sp.2 > Calothrix sp.1 for UO2 2+ and Porphyridium cruentum > Spirulina platensis > Scenedesmus quadricauda for Th 4+. For the same algae it was observed that the retaining degree is much higher for UO2 2+ than for Th4+, probably due to the different linking degrees of hydrolysed species of these ions on the macromolecular compounds of the living cells through the chemical functional groups.
