Iron-Oxidizing Bacteria: A Review of Corrosion Mechanisms in Fresh Water and Marine Environments
Abstract
Models for corrosion influenced by iron-oxidizing bacteria (IOB) in fresh water are specific for material/environment combinations, i.e., 300 series stainless steel exposed to oxygenated chloridecontaining potable water and carbon steel exposed in oxygenated fresh water ([Cl~] < 20 ppb) containing dissolved copper. Reports of IOB influenced corrosion in marine environments have been limited to rusticle formation on shipwrecks. IOB involved in corrosion in fresh water include Gallionella, Leptothrix, and Siderocapsa. Historically these organisms have also been thought to be active in marine environments. New isolation and molecular identification techniques are demonstrating the presence of novel IOB in both freshwater and marine environments, and expanding our understanding of their potential role in microbiologically influenced corrosion.
