Abstract:
Recent advances in electrogenic capabilities of autotrophic microorganisms have given an optimistic alternative for future renewable energy sources. Cyanobacteria Anabaena sp. is currently used as a fertilizer due to its nitrogen fixing ability. However, its application as an electricity generator is not exploited because of the low throughput that is obtained. A better understanding of the relation cells-electrode was intended in this project and optimization of the current signal provided by the bacteria was also studied. The presence of an electro-active natural mediator has been demonstrated and stress induction has appeared as an interesting factor to increase the obtained current. Finally, in order to study the application of Anabaena sp. in the anode of a fuel cell, a Photovoltaic Microbial Fuel Cell was constructed.
