作者列出了在动力学上不利的电化学电池中介导或促进受细菌影响的各种半电池反应对的细菌。这些半电池电极反应的能斯特方程图已被覆盖在铁的电位-pH Pourbaix图上，允许方便地比较腐蚀和生物介导的半电池反应之间的热力学平衡。从这些比较中出现的相关性支持已知的微生物影响的腐蚀（MIC）的机制，并提供了一些新的铁和碳钢在还原条件下的迹象。
The authors have tabulated bacteria that mediate or facititate various pairs of half-cell reactions affected by bacteria in otherwise kinetically unfavorable electrochemical cells. Nernst equation plots of these half-cell electrode reactions have been overlaid on the potential-pH Pourbaix diagram for iron, permitting convenient comparisons of the thermodynamic equilibria between corrosion and biomediated half-cell reactions. Correlations emerging from these comparisons support known mechanisms of microbiologically influenced corrosion (MIC) and provide indications of some new ones for iron and carbon steels in reducing conditions.
