A Surface Analytical Investigation of the Influence of Sulphate Reducing Bacteria on Metallic Corrosion

Abstract

It has long been recognized that Sulphate Reducing Bacteria (SRB) found in natural and industrial waste waters promote Microbiologically Influenced Corrosion (MIC) of certain metals and alloys. X-ray Photoelectron Spectroscopy (XPS) is used in conjunction with conventional microbiological and quantitative chemical analytical techniques to better understand the effect of environmental conditions on microbial behavior as well as the ability of SRB to alter local environmental conditions (such as pH) in such a way as to accelerate corrosion. Specifically, the interactions of Fe, Cr, Ni and Mo ions with Desulfovibrio sp. under anoxic conditions were studied in order to determine the resulting speciation of the metal ions and sulfur.
