The corrosion of iron and steel in the form of storage tanks, pipelines, pumps, and other systems by sulfate-reducing bacteria is a serious problem faced by the petroleum industry. Recently, sulfate-reducing bacteria have been suspected of contributing to failure of certain enhanced (tertiary) oil recovery operations, possibly by degrading polymers used in situ as mobility control agents. Thus almost every aspect of oil recovery can be hindered by the ubiquitous sulfate-reducing bacteria. This review updates the earlier ones by presenting more recent information on the newly discovered strains of sulfate-reducing bacteria, on methods for the cultivation of sulfate-reducing bacteria on agar surfaces, on the bacterial dissimilatory sulfate reduction process, and on novel mechanisms of corrosion by these organisms.
