Microbiologically influenced corrosion is defined by the National Association of Corrosion Engineers as any form of corrosion that is influenced by the presence and/or activities of microorganisms. Although MIC appears to many humans to be a new phenomenon, it is not new to the microbes themselves. Microbial transformation of metals in their elemental and various mineral forms has been an essential part of material cycling on earth for billions of years. Some forms of metals such as reduced iron and manganese serve as energy sources for microbes, while oxidized forms of some metals can substitute for... 

Bacterial corrosion is often referred to as microbiologically influenced corrosion. MIC involves the initiation or acceleration of corrosion by microorganisms. The metabolic products of microorganisms appear to affect most engineering materials, but the more commonly used corrosion-resistant alloys, such as stainless steels, seem to be particularly susceptible.

The second part of the book consists of two chapters namely the forms of corrosion and practical solutions. The chapter, Forms of Corrosion consists of a discussion of corrosion reactions, corrosion media, active and active-passive corrosion behavior, the forms of corrosion, namely, general corrosion, localized corrosion, metallurgically influenced corrosion, microbiologically influenced corrosion, mechanically assisted corrosion and environmentally induced cracking, the types and modes of corrosion, the morphology of corroded materials along with some published literature on corrosion.

When considering the quality of a material, we also must consider the type of material (e.g., metal, resin, glass, or ceramic, etc.). In particular, metal materials exposed to different weather events may be oxidized and corroded. Here, I will focus on corrosion. Carbon steel, stainless steel, and alloys are considered metal materials, and these different types of steel may be chosen according to the purpose of the material and the environment in which the material will be used. However, changes in the environment will shorten the lifetime of the material, and the presence and activity of microorganisms can accelerate corrosion this process is called microbiologically influenced corrosion (MIC) [1-5]. Thus, when... 

Microbiologically influenced corrosion (MIC) is used to designate corrosion resulting from the presence and activities of microorganisms within biofilms on a material surface. Such microorganisms can accelerate and control corrosion reactions by several mechemisms formation of differential or concentration cells, formation of metabolites, such as sulfides md organic and inorganic acids metal oxidation and reduction, and deactivation of corrosion inhibitors. 

The ideal approach to prevent or minimize microbiologically influenced corrosion depends on many factors. These encompass the environment, where MIC occurred (e.g., soil, cooling water, seawater), the type of material damaged, as well as the type of microorganism involved. In practice, several different approaches are usually combined to increase their efficiency. Below, some of the most effective approaches are described briefly. Again, it should be stressed how important a proper identification of MIC and involved microbes is for the choice of effective countermeasures. 

Microbiologically influenced corrosion inhibition (MICI) represents the counterpart to microbiologically influenced corrosion or biocorrosion (MIC). Whereas in the latter case materials are damaged due to detrimental effects exerted by microorganisms or their metabolic products, the former describes the phenomenon of...

In 1990, NACE officially accepted the teim Microbiologically Influenced Corrosion to address this type of corrosion (see Materials Performance (MP), September 1990, p.45). This type of corrosion is also called microbiologically induced corrosion , microbial corrosion or bioconosion. In this book, all of these terminologies will be used interchangeably.
