Magnetite, magnetotactic bacteria magnetosome

Magnetotactic bacteria contain magnetite in the form of magnetosomes, small particles of Fe304. Fe304 is a compound whose atoms are joined by chemical bonds. The electrons in... 

But what does all this have to do with corrosion and MIC There is some indirect and direct evidence here magnetotactic cells can accumulate iron approximately 20,000- to 40,000-fold over its extracellular concentration [118]. Between 14% and 79% by weight of the magnetosome is magnetite (Fe304), where the existence of. .. other oxides of iron or. .. iron sulphides in certain magnetotactic bacteria cannot be mled out [118]. If these bacteria need this much iron, from where can they get it ...
