The term sulfate-reducing bacteria (SRB) is frequently used to describe organisms which metabolize organic sulfates in fuel. Upon metabolism, the oxygen bound to the sulfate sulfur is consumed by the SRB and utilized in cellular respiration. The sulfur is reduced to H2S gas. Once liberated, H2S can react with fuel olefins to form mercaptans, contribute to microbial-induced corrosion, or escape into the fuel. 

The heart of corrosion science has been identified as electrochemical science coupled with the thermodynamic and kinetic values. Other limbs are oxidation and high-temperature oxidation of metals, protective coatings, passivity, inhibitors, microbial-induced corrosion, corrosion fatigue, hydrogen embrittlement and corrosion-resistant alloys. Having identified the limbs of corrosion science, it is instructive to examine how the various aspects came into existence over a period of time. 

Microbiatly induced corrosion (MIC) probes. Devices are available to measure the amount of microbial activity in some environments. Microbially induced corrosion is known to be an actor in many corrosion-related problems in processing plants. The monitoring devices for MIC are limited in their range and, at present, are available only for a few specific environments. This is an exciting area for development of corrosion probes and monitoring systems.

In the light of the knowledge that the earth s raw material resources are limited, the need for the development of modern microbicides which protect valuable products from loss of quality and deterioration is more urgent than ever. They not only protect a great number of perishable products from depreciation and destruction, but also prevent problems in industrial processes caused by algae, formation of slime and biofilms, and microbial induced corrosion. 

The consequences of microbial contamination have been classified into five categories (1) problems caused by the physical presence of microbial growth, (2) problems caused by microbial metabolism, (3) problems caused by microbial metabolites, (4) problems caused by contact with sludge and (5) microbially induced corrosion. These problems are pertinent for aircraft, marine vessels, road vehicles and ground fuel storage.

Metallic materials are an important group of construction materials. Microbially influenced corrosion may occur for these materials for many industrial applications, as listed in Table 1 [27]. Microbially induced corrosion of metallic materials does not involve any new form of corrosion. Thus it is necessary to discuss the electrochemical nature of corrosion briefly before continuing with the mechanisms of MIC for different construction metals. 

In summary, all known cases of microbial corrosion of metals can be attributed to known corrosion mechanisms. In the following sections, the mechanisms of microbially induced corrosion for different metals and alloys are discussed.
