Interaction of Chlorella vulgaris and Schizophyllum commune with U(VI)
U(VI) interaction with biomass was studied using the alga Chlorella vulgaris and the fungus Schizophyllum commune. Both organisms bind significant amounts of U(VI) dependent on its concentration and pH. Interestingly, living Chlorella cells are able to mobilize bound uranium while Schizophyllum cells accumulate large amounts thereof. The molecular structure of formed uranyl-bio-mass-complexes was investigated by different spectroscopic techniques and demonstrated an involvement of carboxylic and organic/inorganic phosphate groups with varying contributions dependent on biomass, uranium concentration and pH.
