Although intergranual and pitting corrosion are the most common in the brewery process, other types of corrosion may occur during the process. While we focussed



Bacterial Corrosion
Corrosion in breweries also occurs due to the presence of microbiological organisms. These organisms accelerate the process of corrosion, oxidizing metals, such as manganese and iron, which are commonly found in tubercles over pits and on steel surfaces [1, p.415].

**rxn of oxidation of these metals** ?

These bacteria derive energy by oxidizing certain metals; therefore, biocorrosion must be mitigated and inspected in order to minimize the risk arising from corrosion. [1, p.415].
