Research Abstract

To examine the roles of semiconductive minerals in the respiratory activity of microorganisms, we cultured the dissimilatory metal-reducing bacterium, Shewanella loihica PV-4, in an electrochemical cell and examined the influence of cell surface-associated Fe-oxide nanocolloids on the extracellular electron-transfer efficiency. The respiratory current was greatly improved (over 50 fold) when α-Fe_2O_3 were supplemented into the cell cultures. In vivo electrochemical studies have revealed that electrons injected from the cells to the conduction band of colloids to move long distances from cell surfaces without the use or requirement of soluble electron shuttles. This finding suggests the microbial ability to exploit semiconductive minerals for transporting and sharing electrons in anaerobic environments.
