Scientists trick iron-eating bacteria into breathing electrons instead
Scientists have developed a way to grow iron-oxidizing bacteria using electricity instead of iron, an advance that will allow them to better study the organisms and could one day be used to turn electricity into fuel. The study will be published on January 29 in mBio®, the online open-access journal of the American Society for Microbiology.
The method, called electrochemical cultivation, supplies these bacteria with a steady supply of electrons that the bacteria use to respire, or "breathe". It opens the possibility that one day electricity generated from renewable sources ...
