Bioreduction of ferric species and biogenesis of green rusts in soils

Iron-reducing bacteria (IRB) communities are widespread and numerous in all main types of soils. IRB are involved efficiently and significantly in the reduction of ferric species and the weathering of iron-bearing minerals under the dependence of physical, chemical, biological parameters. They appear as the major biological agent promoting the formation of green rust mineral (GR) in hydromorphic soils (Gleysols). To cite this article: J. Berthelin et al., C. R. Geoscience 338 (2006).
