Abstract: It is widely recognized that microorganisms promote the degradation of most of the materials in their natural environment, including metallic materials. In the latter case, the presence of bacterial colonies in the form of a biofilm influences the initiation and spread of most attacks corrosion commonly encountered. In other words, biocorrosion is not a form of corrosion, but a change in the kinetics under the influence of the presence of bacteria and products of their metabolism. Among industrial risks necessary to control, the phenomena of biodegradation represent a real danger, which is essential to characterize. So far, the mechanisms leading to the deterioration of materials by the bacterial microflora are not all fully explained. Indeed, the spread of knowledge requires a sustained dialogue between metalworkers, microbiologists, biochemists, chemists and corrosionnistes. A second reason, no less important, is the lack of scientific studies from micro-organisms isolated from the industrial environment.
