Schematic of the biocorrosion reactors. The reactors were gassed with 10% (vol/vol) CO2 and 90% N2 at a rate of 50 ml/min per bioreactor. Each bioreactor contained an iron WE, a platinum CE kept in a separate glass compartment sealed off with an agar plug, and an Ag/AgCl reference electrode (RE). The experimental setup allows the potential (EWE) to be changed while recording the current (iT).
