| Outline of Final Research Achievements |
We tried to isolate microorganisms anaerobically to obtain novel rechargeable material-producing microorganisms. We obtained a single microorganism enable to produce the material. Rechargeable capacitance was approximately 80 μAh mg-1. XRD and EDX analyses revealed that this material consisted of iron and sulfur, which is known as mackinawite. Microbial fuel cell equipped with anode including the material was run. It was confirmed that electron transfer from cells to electrode and rechargeable were observed. Genome analysis revealed that genes closely related to omcBESTZ and MtrABC-OmcA genes were not found, indicating that this strain has another extracellular electron transfer mechanisms. In future plan, we establish the method for making mutant under anaerobic conditions and re-challenge to unveil the rechargeable material-producing mechanism of this strain.
