Usage and Biology
The Microbial Fuel Cell (MFC) can be a future environmentally friendly biotechnological application for the production of electrical energy. As a future alternative energy source, the bioelectricity generation must become more efficient. A major limiting factor is the low bacterial membrane permeability, hindering transport of electron shuttles through the membrane and thereby restricting the electron shuttle-mediated extracellular electron transfer (EET) from bacteria to electrodes. This results in a reduced electrical power output of the MFC. Therefore, we heterologously expressed the porin protein OprF from Pseudomonas fluorescens into Escherichia coli.
