An overview of microbiologically influenced corrosion: mechanisms and its control by microbes

Abstract Metallic materials are widely utilized in the fields of industry, agriculture, transportation and daily life for their high mechanical strength, and relatively low cost. However, the microorganisms that are widely distributed in surroundings can have complicated interactive reactions with metallic materials. The microbiologically influenced corrosion (MIC) has caused serious economic losses and resource wastage for human society. To date, great efforts have been made in the mechanism of MIC and control methods. This work describes the research findings on MIC developed in the recent years, and studies on the common microbial species that affect metal corrosion. The other aim of this paper is to review the accelerating or inhibiting mechanism in metal corrosion. Also, it provides an outlook for research on MIC.
