Anaerobic corrosion is evident as layers of metal sulfides and hydrogen sulfide smell. On cast iron, a graphitic corrosion selective leaching may be the result, with iron being consumed by the bacteria, leaving graphite matrix with low mechanical strength in place. Various corrosion inhibitors can be used to combat microbial corrosion.
The anoxygenic phototrophic iron oxidation was the first anaerobic metabolism to be described within the iron anaerobic oxidation metabolism. The photoferrotrophic bacteria use Fe 2+ as electron donor and the energy from light to assimilate CO 2 into biomass through the Calvin Benson-Bassam cycle (or rTCA cycle) in a neutrophilic environment (pH 5.5-7.2), producing Fe 3+ oxides as a waste ...
Another reaction occurs between iron and water producing iron hydroxide. Fe 2+ + HS − → FeS + H + 3 Fe 2+ + 6 H 2 O → 3 Fe(OH) 2 + 6 H + The net equation comes to: 4 Fe + SO 4 2− + H + + 3 H 2 O → FeS + 3 Fe(OH) 2 + OH −. This form of corrosion by sulfate-reducing bacteria can, in this way, be far more harmful than anaerobic corrosion.

Bacteria-induced anaerobic corrosion of a piece of iron. Anaerobic corrosion (also known as hydrogen corrosion) is a form of metal corrosion occurring in anoxic water. Typically following aerobic corrosion, anaerobic corrosion involves a redox reaction that reduces hydrogen ions and oxidizes a solid metal. [1]
Dissimilatory metal-reducing microorganisms are a group of microorganisms (both bacteria and archaea) that can perform anaerobic respiration utilizing a metal as terminal electron acceptor rather than molecular oxygen (O 2), which is the terminal electron acceptor reduced to water (H 2 O) in aerobic respiration. [1]
The iron in the water is then oxidized by dissolved oxygen or, through enzyme catalysis by iron bacteria (e.g., Thiobacillus ferrooxidans and Thiobacillus thiooxidans) that concentrate the iron as part of their life processes. [4] Presence of these bacteria can be detected by the oily film they leave on the surface of the water. [3]
Acidithiobacillus is a genus of the Acidithiobacillia in the phylum "Pseudomonadota".This genus includes ten species of acidophilic microorganisms capable of sulfur and/or iron oxidation: Acidithiobacillus albertensis, Acidithiobacillus caldus, Acidithiobacillus cuprithermicus, Acidithiobacillus ferrianus, Acidithiobacillus ferridurans, Acidithiobacillus ferriphilus, Acidithiobacillus ...
