Feeding Electricity To Bacteria

Can electricity serve as an alternative electron supplier for bacterial growth? And can we enhance the electron uptake capacity of bacteria? Bacteria utilize both organic and inorganic substances as electron sources for their metabolic activities. Interestingly, our recent studies demonstrate that certain phototrophic bacteria, such as Rhodopseudomonas palustris TIE-1, can use electrically-charged surfaces (cathode) as the
