“…In our study, we found that the sulfate-reducing bacteria increase the copper corrosion rate under immersion conditions after two months in the Z3 (Figure 8): a sufficient duration to develop and produce the different metabolite products in the environment. The mainly products are the sulfide witch form CuS or Cu 2 S. This figure shows a good correlation between the corrosion rate and the evolution of SRB growth [33]. By this result, we propose that in two months of immersion, the quantity of sulfide produced by SRB react with ions of copper dissolved to form CuS or Cu 2 S at the copper surface and increase the metallic dissolution.…”

“…This film changes the characteristics of the metals surface witch become a favorite medium to attract the bacteria and help to their growth to form colonies. This film is known by biofilm and contains the diatoms, funguses, protozoa, microalgaes and their metabolite products [33]. In our study, we found that the sulfate-reducing bacteria increase the copper corrosion rate under immersion conditions after two months in the Z3 (Figure 8): a sufficient duration to develop and produce the different metabolite products in the environment.…”

“…The middle and outer rust layers are mainly made of copper oxides. In many studies with a single strain, it has been observed that the copper sulfides are the main corrosion products, suggesting that the copper sulfide is converted to green rust [33].…”

In this study, the electrochemical corrosion behavior of copper was investigated in seawater collected from four different marine zones of Agadir coastal. These zones are different by the degree of pollution in order to study the effect of this pollution on the copper corrosion, especially the microbial pollution by sulfate reducing-bacteria (SRB). So, to prove this relationship, the microbiological analyses researching the SRB are realized. In parallel, the electrochemical impedance measurement and atomic absorption analysis are established to compare the microbiological evolution cycles with the electrochemical behavior of copper during the immersion period. In the results, we found a good correlation between the growth cycle of marine sulfate-reducing bacteria and the copper corrosion rate by the sulfur and extracellular polymeric substances (EPS) produced as bacteria metabolites. Additionally, this corrosion rate depends on the immersed time: it is maximal after the first or second month depending on the marine zone.

“…SRB reduces sulfate ions to sulfide ions (S 2ˉ) that react with anodic iron ions and form iron sulfide (FeS) that is deposited as corrosion products. The principle reactions explaining bacterial corrosion as reported by authors [17][18] are given by the following equations: Corrosion products:…”

The fiberglass pipes were used for transportation of water in order to maintain the pressure in the oil field of Zarzaïtine (Region of In Amenas located in the south of Algeria). During the maintenance work in summer, a season well known for its extensive heat, the deposits contained in the pipe, and after its contact with the atmosphere, have caused a smoke and it was followed by a fire that ignited a portion of the pipe. To give an answer to the causes of this phenomenon, we have first incriminated the role of specific bacterial species and therefore we have made a microbiological analysis of the deposits collected from the site of the incident. The obtained results revealed the presence of a heterogeneous microbial population with a high concentration level of sulfate-reducing bacteria (SRB), methanogenic bacteria (MB), yeasts and fungi. The interaction between the different species of bacteria and the organic matter contained in the deposits has generated the formation of methane which under the influence of the great heat burnt and the fire caused the ignition of the fiberglass line.
