Geobacteria are a group of bacteria known for their unique ability to transfer electrons to metals and minerals, playing a crucial role in biogeochemical processes. They are often found in anaerobic environments, such as sediments and wetlands, and are notable for their use in bioremediation and bioenergy applications. Geobacter species can oxidize organic compounds and reduce metal ions, making them important in environmental cleanup and microbial fuel cells. Their distinctive conductive pili, known as "nanowires," facilitate electron transfer, enhancing their metabolic capabilities.
