Corrosion of metal materials by microorganisms has long been known as microbiologically influenced corrosion （MIC）. However, little is known about causal microorganisms and their corrosion mechanisms. Poor knowledge about iron-corrosive microorganisms is delaying the development of rapid and accurate diagnostic method against MIC. In this paper, I introduced general knowledge about microorganisms and reviewed about latest knowledge of iron-corrosive microorganisms and MIC investigation. Furthermore, I propose the ideal scheme and future insight of genetic analysis for MIC investigation.
