Mitigation of Microbial Induced Corrosion

Résumé : After deliberating about basics related to corrosion, MIC, different types of bacteria, and their metabolic reactions taking part in the process of corrosion of metals, it is obvious to talk about the ways and means for mitigating MIC. This chapter deals with this aspect in two parts, the first part dealing with the conventional/currently undergoing techniques while the second part dealing with newer/green technology approach for MIC mitigation. One can refer it to MICI, i.e., microbial induced corrosion inhibition. Thus, it deals with not only inhibition of MIC but also microbial induced inhibition of chemical corrosion. First category of methods includes (i) cleaning, (ii) usage of biocides, (iii) coating, and (iv) cathodic protection. Conventionally, mostly adopted procedure to control MIC is by use of biocides. However, biocides pollute the environment, some of them are carcinogenic, and some even corrode material of construction. Consequently, newer methods being suggested have to be environment-friendly. Approach adopted for controlling MIC includes usage of microorganisms which affect (i) production of protective biofilm, (ii) in-situ production of antimicrobials, and (iii) usage of extracellular polymeric substances (EPSs).
