Taking Shewanella and Geobacter as examples, this paper reviewed three kinds of possible mechanisms of microbial enzyme-catalyzed dissimilatory Fe reduction and its molecular regulation, i.e., direct contact between microbial cell and Fe oxides, siderrophores, and electron shuttling compounds. Many membrane-bound cytochrome proteins are involved in the dissimilatory Fe reduction, forming a complicated regulation network.
