Research is being conducted on the corrosion of steel and how it is affected by microorganisms and their byproducts. The influence of different types of biofilms and microorganisms on steel corrosion is being studied, with various factors such as heat treatment, electrical conductivity, and hydrodynamics being considered. The relationship between microorganisms and steel corrosion appears to be complex, with some studies suggesting that microorganisms can both promote and inhibit corrosion.
