This work investigated the effect of Desulfovibrio caledoniensis (D. caledoniensis) and Pseudomonas aeruginosa (P. aeruginosa) on microbiologically influenced corrosion (MIC) behaviour 70Cu-30Ni alloy using surface analysis electrochemical techniques. The results demonstrated that mixed medium containing D. P. further accelerated MIC compared to single species medium. addition exogenous pyocyanin (PYO) increased maximum pit depth from 5.40 μm 6.59 μm, current density (icorr) by one order magnitude. From perspective bioenergetics extracellular electron transfer (EET), comprehensive mechanism induced was proposed.

Abstract Sulfate‐reducing microorganisms extensively contribute to the corrosion of ferrous metal infrastructure. There is substantial debate over their mechanisms. We investigated Fe 0 with Desulfovibrio vulgaris , sulfate reducer most often employed in studies. Cultures were grown both lactate and as potential electron donors replicate common environmental condition which organic substrates help fuel growth corrosive microbes. was corroded cultures a D. hydrogenase‐deficient mutant 1:1 correspondence between loss H 2 accumulation expected for oxidation coupled + reduction . This result extent indicated that not capable direct ‐to‐microbe transfer even though it provided supplementary energy source presence abundant sulfide. Corrosion greater than sterile controls, demonstrating removal necessary enhanced observed The parental ‐consuming strain more strain, could be attributed reduction, producing sulfide further stimulated oxidation. results suggest consumption microbially corrosion, but can indirectly promote by increasing generation from reduction. finding incapable uptake reaffirms metal‐to‐microbe has yet rigorously described sulfate‐reducing

Abstract Microbially influenced corrosion and biofouling emerge as formidable challenges to the sustainable management exploitation of marine resources. The primary instigator for these lies in insidious development biofilm. Hence, most direct pivotal approach counteracting microbial resides advancement anti-biofilm technologies. Conventional methodologies combatting biofilm are efficient but have certain drawbacks, particularly environmental contamination inefficacy. Research into innovative technologies is imperative more use resources protection ecological equilibrium oceans. This paper offers a detailed examination constituents, complex processes involved development, various factors that affect formation, mechanisms underlying microbiologically (MIC). Furthermore, article summarizes emerging, eco-friendly technologies, while providing evolving landscape strategies promising prospects.
