摘要：
Several portions of a uranium mining waste pile sample were supplemented with different amounts of U(VI) in form of uranyl nitrate to investigate the interactions between the indigenous bacterial populations and U(VI). Selective sequential extractions showed that most of the supplemented U(VT) remained predominantly in weak complexes and hence bioavailable. Analysis of 16S rDNA clone libraries from untreated and U(VI)-supplemented samples revealed changes in the structure of the bacterial community.
