Abstract
Microbiologically influenced corrosion (MIC) is the subject of concern in various fields like industries related to healthcare, marine, petroleum, oil, etc. An attempt is made to present MIC and underlying mechanisms. Cathodic depolarization theory along with the other mechanisms supporting MIC caused by sulfate/nitratereducing bacteria is the focus of this chapter. Another important aspect of preventive and mitigation measures of MIC is concerned.
