Bacterial and bio-fouling corrosion

Biological organisms affect corrosion processes on metals by directly influencing anodic and cathodic reactions, by affecting protective surface films on metals, by producing corrosive substances and by producing solid deposits. These organisms include microscopic forms, such as bacteria, and macroscopic types, such as algae and bamacles. Microscopic and macroscopic organisms have been observed to live and reproduce in mediums with pH values between 0 and 11, at temperatures between 0 and 80 °C (30 and 180 °F), and under pressures up to 103 MPa (15 ksi). Thus, biological activity may influence corrosion in a variety of environments, including soil, inland water and seawater, crude oil and petroleum products, and in oil-emulsion cutting fluids.
