Introduction
By [Kyle Bailey]
Metal Respiration
Microbial Fuel Cell (MFC)
Figure 2. A diagram of a (microbial fuel cell) MFC containing a graphite anode that is serving as a final electron acceptor. The bacteria are performing anaerobic microbial oxidation on the various organic compounds present. In the middle of the anaerobic anode and aerobic cathode is a proton diffusion layer that separates them showing that water is formed at the cathode (Franks and Nevin., 2010).
Figure 3. In current producing biofilms bacterial cells conduct electron transfer using membrane bound cytochromes. The bacterial cells use a long range network capable of conducting electron flow from the farthest cells to the closest ones to the anode. Oxidation of the organic substrate leads to a high concentration of protons under the biofilm mass where it is highest towards the anode (Franks and Nevin., 2010).
Conclusion
Overall text length at least 3,000 words, with at least 3 figures.
