Abstrakt: Corrosion of mild steel in cultures of a Pseudomonas species under the condition of simultaneous formation of Fe(II) and S2- was initially inhibited by inhibiting the anodic reaction, but after long incubation the corrosion process was allowed to continue. When only S2- was produced, the initial corrosion rate increased for up to 60 h but later declined, probably due to a protective FeS film formed on the metal. Cathodic reactions were affected in a similar fashion as the anode.
