Abstract

MIC (Microbiologically influenced corrosion) is an electrochemical type of corrosion enhanced by some typesof micro-/ macro-organisms. However, in this paper, MIC will be used to address the corrosion enhanced bymicro-organisms. In order for MIC to occur, two minimum requirements are (i) vulnerability of the material and(ii) existence of environmental factors that are favoring MIC. This type of corrosion is known to affect bothmetals and non-metals. On the other hand, the factors that render the environment suitable for MIC are, but notlimited to, pH, temperature, systems, dynamics, and availability of chemicals such as carbon source necessaryfor sustaining the growth of corrosion-enhancing bacteria. Under natural conditions, bacteria are usually found innon-pure, mixed communities known as “mixed cultures” or “microbial consortia”. When a certain material isexposed to a known, in-engineering-terms “uniform” group of bacteria (such as all Desulfovibrio desulfuricans),it is easier to explain the corrosion mechanism (s) than a mixed culture will be affecting different constructingmaterials of a given system. In this paper, corrosive effects of some known types of bacteria (such as sulphatesreducing bacteria and sulphur oxidizing bacteria) on enhancement of corrosion of carbon steel and concrete arereviewed. At the end, some general guide lines for prevention of MIC on these materials are also outlined.
