Iron-Reducing Bacteria and Iron Nanostructures

Alireza Ebrahiminezhad, Zahra Manafi, Aydin Berenjian, Sedigheh Kianpour, Younes Ghasemi


Iron Reducing Bacteria (IRB) are one of the most applicable microorganisms in various industrial and environmental activities. These bacteria play a main role in the natural iron transformation. They act in a reverse metabolic pathway in contrast to iron oxidizing bacteria. In the anaerobic conditions IRB are capable to use ferric ion as the final electron acceptor and reduce Fe3+ to Fe2+. What makes these bacteria interesting in bionanotechnology is that IRB are able to synthesize iron nanostructures. In this mini review we have a quick look on the diversity, metabolism, and cultivation of IRB. Finally, we discuss iron nano structures which biosynthesized by IRB.
