“…A freshly prepared Clarke's solution was used to remove bio lms and corrosion products before weighing each coupon adhering to ASTM G1-03 (Lu et al, 2023b). Pit depths were scanned using a different CLSM machine (VK-X250K, Keyence, Osaka, Japan).…”

“…Such deteriorations can lead to catastrophic structural failures if not mitigated. Among the microbes that can cause serious MIC, SRB (sulfate reducing bacteria) accounted for the largest number of severe corrosion cases (Anandkumar et al, 2016;Lu et al, 2023b;Su et al, 2022). D. ferrophilus (strain IS5) is by far the most corrosive marine SRB.…”

Most microbiologically influenced corrosion (MIC) studies focus on the threat of pinhole leaks caused by MIC pitting. However, microbes can also lead to structural failures. Tetrakis hydroxymethyl phosphonium sulfate (THPS) biocide mitigated the microbial degradation of mechanical properties of X80 pipeline steel by Desulfovibrio ferrophilus, a very corrosive sulfate reducing bacterium. It was found that 100 ppm (w/w) THPS added to the enriched artificial seawater (EASW) culture medium before incubation resulted in approximately 3-log reduction in sessile cell count after a 7-d incubation at 28oC, leading to 94% weight loss reduction. The X80 dogbone coupon incubated with 100 ppm THPS for 7 d suffered only 3% loss in ultimate tensile strain and 0% loss in ultimate tensile strength compared with the abiotic control in EASW. In comparison, the no-treatment X80 dogbone suffered losses of 13% in ultimate tensile strain and 6% in ultimate tensile stress, demonstrating very good THPS efficacy.

“…For instance, 317L-Cu stainless steel (SS) exhibited considerable antibacterial activity against Staphylococcus aureus, reducing sessile cell counts by 98.3% compared to 317L SS [ 120 ]. In Escherichia coli -containing medium, 304L-Cu SS had shallower pitting depth and lower weight loss than 304SS, with 304L-Cu SS’s corrosion current density being four times lower than 304SS’s due to copper’s bactericidal effects [ 121 , 122 ]. Similarly, HNS-Cu and 2205-Cu DSS yielded comparable outcomes [ 123 , 124 ].…”

Microbially influenced corrosion (MIC) is a formidable challenge in the marine industry, resulting from intricate interactions among various biochemical reactions and microbial species. Many preventions used to mitigate biocorrosion fail due to ignorance of the MIC mechanisms. This review provides a summary of the current research on microbial corrosion in marine environments, including corrosive microbes and biocorrosion mechanisms. We also summarized current strategies for inhibiting MIC and proposed future research directions for MIC mechanisms and prevention. This review aims to comprehensively understand marine microbial corrosion and contribute to novel strategy developments for biocorrosion control in marine environments.
