Electroactive bacteria are a unique group of microorganisms that can transfer electrons to and from their environment. They play a crucial role in various natural processes, such as biogeochemical cycles and bioenergy production. These bacteria can utilize metals and other compounds as electron acceptors, enabling them to thrive in diverse habitats, including soil and aquatic environments. These bacteria are of great interest for applications in bioelectrochemical systems, such as microbial fuel cells and biosensors. By harnessing their ability to generate electricity from organic matter, researchers aim to develop sustainable energy solutions and improve wastewater treatment processes.
