“…Although the rate of this reaction is very slow, it may be catalyzed by different chemical species such as inorganic and organic mediators (Fe 2+ and Polypirrole, respectively ). Abiotic oxygen reduction may result from different pathways : according to a single step, in four-electron mechanism (reaction 1), or two successive electron reduction steps according to reactions 2 and 3, that is, with the intermediate formation of hydrogen peroxide , as follows: The oxygen reduction mechanism on SS surfaces is strongly influenced by biofilms . In fact, prior to the formation of a biofilm, oxygen reduction occurs in a single step (reaction ).…”

“…After a while, the biofilm grows on the metal surface and E corr ennobles to positive values. On the basis of cathodic polarization tests, Shams El Din et al postulated that once the biofilm settles, oxygen reduction occurs in two successive electron-reduction steps (reactions 2 and 3). Significant concentrations of H 2 O 2 were detected as a result of the reduction of oxygen on metals immersed in seawater , .…”

“…The reduction of oxygen is considered as the driving force in aerobic corrosion. The development of a biofilm on SS surfaces modifies the oxygen reduction wave: a displacement toward anodic values (between 0 and +300 mV/SCE) and an increase of the current density ,,,,,,, . Scotto et al and Mollica suggested that one of the ways by which biofilm formation may favor these phenomena is through enzymatic catalysis.…”

The electrochemical behavior of stainless steels (SS) in natural waters is characterized by the ennoblement of their free corrosion potential (E(corr)). This phenomenon depends strongly on the settlement of biofilms on SS surfaces. Many hypotheses have been proposed to explain the biofilm action, in particular the enzymatic catalysis plays an important role by shifting the cathodic and/or anodic processes. However, there are still only few studies relating the use of purified enzymes. In contrast with bacteria-associated corrosion, the direct influence of enzymes is still poorly documented. The aim of this review is to show the benefits of the enzymatic approach in the study of biocorrosion. Indeed, enzymatic systems may constitute convenient models to mimic microbial influenced corrosion and to evaluate the behavior of metallic materials in natural waters.

“…Many metals are sensible to MIC. Pitting, crevice corrosion, hydrogen embrittlement and deposit corrosion caused by MIC almost involve all kinds of fields, such as petrochemical industry, aviation, shipping, powder industry and so on [2][3][4][5][6]. According to statistics, MIC accounted for 20% in metal and building materials corrosion damages [7].…”

The impacts of microorganism on brass corrosion were studied in static experiment in this paper. Two main factors, temperature and concentration ratio, were considered. According to the actual operation of recycling cooling water system, four temperatures (15˚C, 25˚C, 35˚C and 45˚C) and four concentration ratios (1, 2.5, 3.5 and 4.5) were selected in the experiment. Corrosion potential, current density, average corrosion rate were measured by time. The results showed that: microorganism often aggravated corrosion of brass during initial and final stages, but alleviated its corrosion at the middle time. With the extension of time that brass immersed in the solution, the microbes began to intensify the corrosion of the metal. When concentration ratios were 2.5 and 3.5 and temperature was 15˚C, microbe promoted brass corrosion obviously and corrosion degrees.
