Biofilms were used to produce gramicidin S (a cyclic decapeptide) to inhibit corrosion-causing, sulfate-reducing bacteria (SRB). In laboratory studies these biofilms protected mild steel 1010 continuously from corrosion in the aggressive, cooling service water of the AmerGen Three-Mile-Island (TMI) nuclear plant, which was augmented with reference SRB. The growth of both reference SRB (Gram-positive Desulfosporosinus orientis and Gram-negative Desulfovibrio vulgaris) was shown to be inhibited…

TLDR
Scanning electron microscope images corroborated the corrosion inhibition by the gramicidin-S-producing B. brevis biofilm on mild steel by showing that the metal surface remained untarnished, i.e., the polishing grooves were still visible after exposure to the simultaneous attack of the sulfate-reducing bacterium and the iron-oxidizing bacterium.
Microbial Corrosion of API 5L X-70 Carbon Steel by ATCC 7757 and Consortium of Sulfate-Reducing Bacteria
Various cases of accidents involving microbiology influenced corrosion (MIC) were reported by the oil and gas industry. Sulfate reducing bacteria (SRB) have always been linked to MIC mechanisms as

TLDR
Successful utilization of this novel strategy: corrosion control using beneficial bacteria biofilms relies on advances in study at the interface of corrosion engineering and biofilm biology.
Biofilms affecting progression of mild steel corrosion by Gram positive Bacillus sp.
The biodeterioration of metals have detrimental effects on the environment with economic implications. The deterioration of metals is of great concern to industry. In this study, mild steel coupons
Role of Microorganisms in Corrosion Induction and Prevention
Microbiologically-influenced corrosion (MIC) is defined as the deterioration of metals as a result of metabolic activities of microbes. The biological harmful activities modify local chemistry and
Influence of nitrate concentrations on EH40 steel corrosion affected by coexistence of Desulfovibrio desulfuricans and Pseudomonas aeruginosa bacteria
Nitrate addition is a common bio-competitive exclusion (BCE) method to mitigate corrosion in produced water reinjection systems, which can affect microbial community compositions, especially nitrate
Inhibition of bio corrosion of steel coupon by sulphate reducing bacteria and Iron oxidizing bacteria using Aloe Vera ( Aloe barbadensis ) extracts
The inhibition of biocorrosion of steel coupons by sulphate reducing bacteria (SRB) and Iron oxidizing bacteria (IOB) using Aloe vera ( Aloe barbadensis ) extract was tested. The water sample
Shielding for Microbiologically Influenced Corrosion of Mild Steel by Antagonistic Bacterial Cultural Fluids
TLDR
Vivid decreases in corrosion rates of the experimental microbiologically influenced corrosion demonstrated that the presence of cell free cultural fluids of bacterial antagonists not only reduced the intensity of MIC but they protected the mild steel from abiotic corrosion too.
Corrosion risk associated with microbial souring control using nitrate or nitrite
TLDR
SRB control by nitrate or nitrite reduction shifts the corrosion risk from the bioreactor outlet to the inlet (i.e. from production to injection wells) and souring treatment by continuous addition of a high inhibitory nitrite dose is preferable from a corrosion-prevention point of view.

Inhibiting sulfate-reducing bacteria in biofilms on steel with antimicrobial peptides generated in situ
TLDR
Addition of either 200 μg/ml ampicillin, chloramphenicol, or ammonium molybdate to batch and continuous reactors after SRB had colonized the metal was ineffective in killing SRB, as inferred from the lack of change in both Rp and the impedance spectra.
Axenic aerobic biofilms inhibit corrosion of SAE 1018 steel through oxygen depletion
Abstract Corrosion inhibition of SAE 1018 steel by pure-culture biofilms of Pseudomonas fragi and Escheri-chia coli DH5α has been evaluated in complex Luria-Bertani medium, seawater-mimicking medium,
Axenic aerobic biofilms inhibit corrosion of copper and aluminum
TLDR
This is the first report of axenic aerobic biofilms inhibiting generalized corrosion of copper and aluminum and is able to lessen corrosion as evidenced by a consistent 20-fold increase in the low-frequency impedance value of copper as well as a consistent four- to seven-fold rise in the polarization resistance of aluminum 2024 after six days exposure compared to sterile controls.
Importance of biofilm formation for corrosion inhibition of SAE 1018 steel by axenic aerobic biofilms
TLDR
It appears that only a small layer of active, respiring cells is required to inhibit corrosion, and the corrosion inhibition observed is due to the attached biofilm.

TLDR
A perspective is provided on corrosion inhibition by bacterial biofilms and the processes that make it difficult to predict and control.
Role of microorganisms in corrosion inhibition of metals in aquatic habitats
TLDR
Chemoorganotrophic Fe(III) reducers are of special interest because they remove corrosion products and hence destroy ecological niches for sulfate-reducing bacteria beneath the deposits and cause passivation of the metal surface through the consumption of dissolved oxygen.
