Abstract

The numerous structural impacts on oil installations caused by corrosion make this issue a concern in the oil industry. Although chemical corrosion is relevant in this sector, it is indisputable that the microbial corrosion or bio-corrosion plays a preponderant role, with considerable economic losses. Microbial corrosion invariably depends on the formation of a biofilm on the attacked surface. Biofilm structures provide the conditions that favor the development of microbial groups related to corrosion. Despite the several microbial species are described as corrosive, certain groups, such as sulfate- and nitrate-reducing bacteria, acetogenic bacteria, and methanogenic archaea are the most commonly related. In spite of environmental factors influence the prevalence of certain species, it is increasingly accepted that the relationships between different species are determinant in corrosion. Such relationships can be evidenced by several surveys of microbial communities involved in bio-corrosion. Here, the main microbes related to corrosion in metallic structures used in oil installations are presented, as well as their metabolisms involved in the deterioration of metallic surfaces.
