13-07: Microbial Corrosion on Metallic Surfaces

The underlying conclusion to past studies on microbial corrosion is that it is a complex subject, still not yet well understood. It’s been found that many bacterial species can be part of the corrosion process, different metal surfaces show different progressions of corrosion, and microbes can also inhibit corrosion of the metals. There is no consensus as to the role microbes can play; it is quoted from varying sources that microbial induced corrosion is involved in the range of 2% to 90% of problem. This paper summarizes the process and proposes a simple research approach.
