The Relationship Between Corrosion and the Biological Sulfur Cycle.

Abstract

Most microbiologically influenced corrosion (MIC) takes place in the presence of microbial consortia in which many different physiological types of bacteria interact in complex ways within the structure of biofilms. Microbiologically-mediated oxidation and reduction reactions of sulfur and sulfur compounds are important contributors to MIC. Sulfur and sulfur compounds, including sulfides, bisulfides, hydrogen sulfide (H2S), thiosulfates, polythionates and sulfuric acid, may be trapped or bound up in biofilms causing direct corrosion of materials. H2S and sulfuric acid may become gaseous or waterborne.
