Scientists discover electricity-conducting bacterium in Oregon
They can find applications in bioelectronics and be useful in processes that purify the environment. Electrothrix yaqonensis is an extraordinary bacterium that has the ability to conduct electricity and clean the environment.
Scientists have identified a new species of bacteria, Candidatus Electrothrix yaqonensis, which can conduct electricity. The discovery was published in "Applied and Environmental Microbiology" and may pave the way for innovative bioelectronic technologies. The unique properties of these microorganisms can find applications in medicine, industry, food safety, and environmental monitoring and protection.
The ability of living organisms to conduct electricity reduces the gap between biology and technology. Electrically-conducting bacteria are exceptional organisms capable of transporting electrons outside their cells. They use special nanofibres for this process, which transmit electrical charges. These microorganisms consist of rod-shaped cells that connect to form filaments reaching several centimetres in length. Their unique ability to conduct electricity is rare among bacteria and represents an adaptation that optimises metabolic processes in sedimentary environments.
Unique bacterium Candidatus Electrothrix yaqonensis
The bacterium was discovered in coastal sediments in the state of Oregon by a research team from the State University. C. Electrothrix yaqonensis stands out with unique structural features, including distinct surface ridges that contain highly conductive fibres made of unique nickel molecules.
Bacteria clean the environment
According to SciTech Daily, the new species of bacteria has the ability to transport electrons over long distances, allowing it to participate in reactions occurring in sediments. As a result, these bacteria can play a crucial role in geochemistry and nutrient cycling. Research shows that these microorganisms are also useful in removing contaminants from sediments.
Research on the new bacterium was supported by various institutions, including the University of Antwerp, Delft University of Technology, and the University of Vienna. The project was funded by the Office of Naval Research, Oregon Sea Grant, and other European research funds.
