Introduction
Fe(Ⅱ) in E.coli causes Fenton reaction in response to hydrogen peroxide and produce hydroxyl radical (OH･) which is harmful to E.coli. As a result, giving iron to E.coli excessively leads to the death of E.coli.
Ferritin is an intracellular protein which has a property to store iron. Ferritin has Heavy chain and Light chain. Heavy chain affects the oxidation of iron and stimulate 2Fe(Ⅱ)＋O2→[Fe(III)-O-O-Fe(III)] reaction. Light chain takes in Fe(Ⅲ) in ferritin. Fe2O3(H2O) has paramagnetism.
These two effects enable isolation of iron in ferritin and produce E.coli with strong iron tolerance.
