Chloride Enhances Corrosion Associated with Sulfate-Reducing Bacteria authors.elsevier.com/c/1j303,Fwi-Rhq No genes, no gels, no high-end analytics, just basic culturing to provide the simple explanation for what was erroneously considered a paradigm shift in microbial corrosion mechanisms.

Taking Corrosion Mechanisms Claims with a Grain of Salt: “Chloride Enhances Corrosion Associated with Sulfate-Reducing Bacteria” sciencedirect.com/science/articl… For two decades rapid corrosion by some Desulfovibrio was attributed to a radically new mechanism of corrosion. Actually, the simpler explanation is that differences in chloride concentrations in the different cultures were responsible for the corrosion rate differences.
