Key role of the kinetics of γ-FeOOH bioreduction on the formation of Fe(II–III) minerals

Résumé

During bacterial reduction of γ-FeOOH lepidocrocite in the presence of formate as electron donor at initial pH 7.5 in bicarbonate buffer, the obtained Fe(II–III) minerals were characterised by transmission Mössbauer spectroscopy (TMS) and X-ray diffraction (XRD). Two types of kinetics, high and slow, of γ-FeOOH bioreduction were obtained. The high rate of ferric oxyhydroxide reduction produced magnetite whereas the slow rate yielded hydroxycarbonate green rust.
