Biocorrosion can be produced by many different microorganisms through diverse mechanisms. The biocorrosion produced by acidophilic microorganisms of the genus Thiobacillus is based on the production of sulfuric acid and ferric ion from pyrites or related mineral structures, as a result of the chemolithotrophic metabolism of these microorganisms. The products of this aerobic respiration are also powerful oxidant elements, which can produce chemical oxidations of other metallic structures. The Tinto River, a very unusual extremophilic habitat (pH around 2, and high concentration of ferric ion), product of the growth of strict chemolithotrophic microorganisms, is discussed as a model case.
生物腐蚀可由许多不同的微生物通过多种机制产生。硫杆菌属嗜酸微生物产生的生物腐蚀是基于这些微生物的化能无机营养代谢，从黄铁矿或相关矿物结构中产生硫酸和铁离子。这种有氧呼吸的产物也是强大的氧化元素，可对其他金属结构产生化学氧化作用。作为一个典型案例，文中讨论了廷托河，它是一个非常特殊的极端嗜生境（pH值约为2，铁离子浓度高），是严格化能无机营养微生物生长的产物。
