Molecular Mechanisms of Microbially Facilitated Corrosion

Abstract

Mechanisms such as the formation or utilization of hydrogen, the generation of mineral or organic acids, the generation of effective metal chelators, the active reduction of metals with the creation of areas of differential cathodic activity are postulated. Sensitive methods for microbial community structure, metabolic activities, and nutritional status have been developed utilizing signature been correlated with nondestructive Fourier transform spectroscopy (FT/IR) and electrochemical measures of corrosion potential. With these the potential for microbial consortia to form microcolonies have been shown to allow enhanced MFC in which multiple secreting heterotrophs form microcolonies and create anaerobic microniches in aerobic bulk water that allow acid secreting or hydrogen utilizing anaerobes to function and induce MFC.
