The effect of Shewanella Oneidensis MR-1 on Microbial Influenced Corrosion (MIC)

Iron-reducing-bacteria (IRB) play important roles in geochemical cycling of iron. Under anaerobic conditions, IRB is capable of reducing insoluble iron (III) to soluble iron (II). Despite its direct involvement in iron redox reactions, the role of IRB in Microbial-Influenced-Corrosion (MIC) remains...
