in: Microbiologically Influenced Corrosion: A Comprehensive Guide to Principles, Assessment and Mitigation, CRC Press, pp.13-60, 2026
Microbiologically influenced corrosion (MIC) represents a complex and poorly understood materials degradation phenomenon with significant implications across various industries. MIC arises from the interaction between microorganisms, materials, and environmental conditions, resulting in accelerated corrosion rates and substantial economic and safety challenges. This chapter provides an interdisciplinary overview of MIC by introducing its underlying microbiological, environmental, and electrochemical principles, as well as the diverse microbial communities and environmental factors that contribute to corrosion processes. It also explores the roles of biofilms and microbial energy strategies in shaping corrosion kinetics and influencing materials degradation. A significant component of the chapter is a Europe-wide survey conducted under the Euro-MIC COST Action initiative, which offers unique insights into how professionals across sectors detect, monitor, and mitigate MIC. The survey results underscore a widespread reliance on traditional methods, limited awareness of relevant standards, and underutilization of advanced diagnostic tools, despite a clear demand for more effective, accessible, and real-time solutions. The chapter emphasizes the need for stronger collaboration between industry and academia, increased standardization, and enhanced knowledge transfer.
