Short summary

Mineral binding is a major mechanism for soil carbon (C) stabilization. However, soil minerals can also inhibit the growth of bacteria that protect organic C from decay. Here the findings indicate that reduced surface Fe(II) derived from Fe(III)-containing minerals inhibits the growth of bacteria via a free-radical mechanism, which may serve as an ubiquitous mechanism between iron minerals and all of the heterotrophic bacteria in view of bacteria as a vast source of superoxide.
