AMPP Cathodic Protection Technician (CP2) Practice Exam

Microbiologically Influenced Corrosion (MIC) predominantly thrives in anaerobic conditions, which means it occurs in environments that lack oxygen. Many types of bacteria and other microorganisms that cause MIC require anaerobic environments to proliferate and induce corrosion processes. While some forms of corrosion can occur in aerobic environments with the presence of certain microorganisms, MIC is specifically associated with the metabolic activities of anaerobic bacteria, such as sulfate-reducing bacteria, which are known for their capacity to accelerate the corrosion of metals by creating localized corrosive environments.

The selected answer is correct because it accurately reflects the core understanding of MIC's requirements. Under aerobic conditions, the types of microorganisms present generally do not contribute to MIC to the same degree as their anaerobic counterparts. Understanding the environment in which MIC occurs is crucial for effective corrosion management and implementing cathodic protection strategies.
