AbstractCultures of sulfate-reducing bacteria and methanogenic bacteria utilized cathodic hydrogen during anaerobic corrosion processes for sulfate reduction and carbon dioxide reduction respectively. But Fe°-oxidation was not stimulated by the consumption of H<sub>2</sub> or by the presence of methane bacteria. Growth of sulfate-reducing bacteria with cathodic hydrogen as electron donor was combined with increasing Fe<sup>2+</sup> formation. Hydrogenase-negative <i>Desulfococcus multivorans</i> enhanced iron corrosion (Fe°-oxidation) by forming H<sub>2</sub>S and thus accelerating both anodic and cathodic reactions.
