Abstract
Treatments with uranyl nitrate induced strong changes in subsurface bacterial community of a uranium mining waste pile. Most of the bacterial populations, stimulated at the initial stages of the treatment, used the added nitrate for respiration. Mössbauer spectroscopic analyses showed that at the later incubation stages, when nitrate was reduced, reduction of Fe(III) to Fe(II) occurred. Time-resolved laser-induced fluorescence spectroscopic analysis revealed that most of the added U(VI) was bound in phosphate phases of biotic origin.
