As a result of such chicanery, the voter rolls in many American cities and counties â in such states as South Dakota, Texas, Mississippi, Kentucky, Indiana, West Virginia, Maryland, Iowa, North Carolina, and Missouri â soon included more names than there were residents of voting age in those locales.
From Wikipedia, the free encyclopedia. Microbial corrosion, also called bacterial corrosion, bio-corrosion, microbiologically influenced corrosion, or microbially induced corrosion (MIC), is corrosion caused or promoted by microorganisms, usually chemoautotrophs.It can apply to both metals and non-metallic materials.acterial corrosion may appear in form of pitting corrosion, for example in pipelines of the oil and gas industry. Anaerobic corrosion is evident as layers of metal sulfides and hydrogen sulfide smell.
Industrial Impact. Microbiologically influenced corrosion usually occurs in aqueous environments such as water treatment and sewage plants, but is also common in other sectors of the economy, from oil and gas production systems to underground pipelines and chemical processing plants[11].echanism. Corrosion, the oxidation of metal, requires the simultaneous reduction of another chemical. MIC usually takes place in stagnant water, and either dissolved oxygen or hydrogen is reduced in order for the process to proceed[1].
