… 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 … The purpose of this paper is to illustrate the occurrences of bacterial reduction
processes of ferric species, and more specifically the reduction–dissolution and weathering …
