iron sulfide

The gradual reduction (decomposition) of metals due to chemical and electrochemical interactions is called corrosion, which causes significant financial losses to industries every year. For example, in water systems, various types of corrosion are defined as an electrochemical process.

Corrosion by sulfate-reducing bacteria was first discovered in the Netherlands in 1934. Sulfate-reducing bacteria, abbreviated as SRB, live in aquatic environments, deep underground and in the seas, where dissolved oxygen is minimal.
