“…When steel was completely covered by the biofilm, the bacteria inhibited corrosion, likely due to O 2 scavenging, whereas when steel was partially covered, corrosion was accelerated in the uncovered area. MIC inhibition has also been indicated for some species of the Pseudomonas genus 59,60 . Studies suggest that biopassivation of the steel is influenced by the production of extracellular polymeric substance (EPS) and biofilm structure that prevent corrosive species in the bulk solution from reaching the metal surface.…”

Corrosion of carbon steel by microorganisms recovered from corroded seal rings at an offshore floating production facility was investigated. Microbial diversity profiling revealed that communities in all sampled seal rings were dominated by Pseudomonas genus. Nine bacterial species, Pseudomonas aeruginosa CCC-IOB1, Pseudomonas balearica CCC-IOB3, Pseudomonas stutzeri CCC-IOB10, Citrobacter youngae CCC-IOB9, Petrotoga mobilis CCC-SPP15, Enterobacter roggenkampii CCC-SPP14, Enterobacter cloacae CCC-APB1, Cronobacter sakazakii CCC-APB3, and Shewanella chilikensis ccc-APB5 were isolated from corrosion products and identified based on 16S rRNA gene sequence. Corrosion rates induced by the individual isolates were evaluated in artificial seawater using short term immersion experiments at 40 °C under anaerobic conditions. P. balearica, E. roggenkampii, and S. chilikensis, which have not been associated with microbiologically influenced corrosion before, were further investigated at longer exposure times to better understand their effects on corrosion of carbon steel, using a combination of microbiological and surface analysis techniques. The results demonstrated that all bacterial isolates triggered general and localised corrosion of carbon steel. Differences observed in the surface deterioration pattern by the different bacterial isolates indicated variations in the corrosion reactions and mechanisms promoted by each isolate. Corrosion is a ubiquitous problem that affects almost all industrial sectors including oil and gas production, transportation and refining facilities 1,2 , mining 3 , marine engineering and shipping 4,5 , industrial water systems 6 , food processing plants 7 , nuclear industries 8 , among others. This phenomenon occurs via electrochemical reactions, where electrons are released from the metal at anodic sites and are gained at cathodic sites 9. Although assessment of the cost of corrosion is difficult, the NACE International IMPACT study estimated the global cost of corrosion as US$2.5 trillion in 2013 10. Microbiologically influenced corrosion (MIC) has been estimated to contribute at least 20% to 40% of the total corrosion costs 11,12. The loss of integrity of industrial infrastructure can result in substantial economic, environmental, health, safety and technological consequences 13. MIC is a type of corrosion in which the deterioration of metals occurs due to the presence and activity of microorganisms 14. Microorganisms initiate, facilitate or accelerate corrosion reactions by altering the electrochemical conditions in the metal-solution interface 15. Compared to other forms of corrosion, MIC is highly unpredictable and occurs at rates as high as 10 mm year −116. Early detection of MIC is difficult due to its localised nature and the wide range of environmental conditions and associated microorganisms 17. MIC has been proposed as the cause of failure in many significant incidents in the hydrocarbon industry such as the propane tank leak and explosion in Umm Said NGL Plant (Qatar) 18 , the natu...

“…Such effect was attributed to attachment and colonization of microorganisms, the microbial metabolically secreted organic molecules adsorbed on the Q235 CS surface and decreased the corrosion rate. Afterwards till day 12, the diameter became narrowed and even smaller than initial value, suggested destruction of protective layer occurred overtime which possibly due to exfoliation of biofilm-corrosion product complex or local defect (Suma et al 2019).…”

“…It has been reported some microorganisms were capable of retarding metal corrosion, namely microbiologically influenced corrosion inhibition (MICI). In the study of (Suma et al 2019), Pseudomonas putida attached on mild steel surfaces by secreting adhered EPS and accelerating biofilm formation. The Fe-EPS and stable vivianite constituted the biopassivated layer offered mild steel a long-term corrosion.…”

In this study, 6 strains of microbial agents were investigated as environment-friendly scale and corrosion inhibitors for industrial cooling water applications. The static jar tests along with characterization methods were applied to evaluate the scale inhibition performance. Results showed that under a concentration of 240 mg/L, the Nitrobacteria, Denitrobacteria and Lactobacillus agents reached high CaCO3 scale inhibition efficiencies of 83, 82, and 86% respectively. Characterization methods indicated the deposited crystals morphologies were modified and the crystals peak intensities were lowered. In addition, weight loss measurements, electrochemical measurements, surface characterization analyses were conducted to study the corrosion inhibition performances and mechanisms. It was found that at 40 °C, Bacillus cereus agent with 200 mg/L possessed the highest corrosion inhibition efficiency of 60.11% at 3 d, together with the second-lowest current density of 13.0 μA cm−2 at 12 d. The corrosion inhibition mechanisms were attributed to biofilm accumulation and biomineralization on Q235 CS surfaces to form protective film. The results suggested microbial agents have promising potential as environment-friendly scale and corrosion inhibitors for industrial cooling water applications.
