Abstract:

The primary objective of this project was to understand the role that the iron-oxidizing bacteria, a unique group of chemolithoautotrophic microbes, play in the corrosion of steel. Despite significant research showing that microbially-induced corrosion MIC is an important contributor to the corrosion and destruction of steel structures, almost no previous work has been done to show what effects Fe-oxidizing bacteria may have on this process. Corrosion is a major issue for the Naval fleet, as well as fixed and floating assets that support fleet operations. Four lines of inquiry were identified in line with the primary objective.
