Microbially Influenced Corrosion (MIC) is defined as corrosion that is caused or exacerbated by microorganisms (bacteria, fungi). It is often facilitated by microbial biofilms--communities of microorganisms that associate with a material and attack the material through the production of enzymes and metabolites. The risk and rate of MIC is driven by a combination of the composition of the microbial community, the chemistry of the material, and the environmental conditions under which the microorganisms persist, which in turn drive their metabolic processes. Our laboratory examines how degradative processes are influenced by microbial physiology, microbial community dynamics and spatial-temporal relationships within biofilm communities. We use molecular, genetic, biochemical, microscopic and spectroscopic tools to characterize microbial biofilms and determine their effects on materials. These fundamental studies are the foundation of many applied technology efforts for aerospace and fuel systems management, which include detection and mitigation of MIC and biofouling.
