Biostimulation of indigenous microbes for uranium bioremediation in former U mine water: multidisciplinary approach assessment.

ABSTRACT: Characterizing uranium (U) mine water is necessary to understand and design an effective bioremediation strategy. In this study, water samples from two former U-mines in East Germany were analysed. The U and sulphate (SO₄^2-) concentrations of Schlema-Alberoda mine water (U: 1 mg/L; SO₄^2-: 335 mg/L) were 2 and 3 order of magnitude higher than those of the Pöhla sample (U: 0.01 mg/L; SO₄^2-: 0.5 mg/L). U and SO₄^2- seemed to influence the microbial diversity of the two water samples. Microbial diversity analysis identified U(VI)-reducing bacteria (e.g. Desulfurivibrio) and wood-degrading fungi (e.g. Cadophora) providing as electron donors for the growth of U-reducers. U-bioreduction experiments were perform
