Oregon State University researchers have discovered a unique organism capable of carrying electrical currents similar to wires in a circuit. The bacteria, named Ca. Electrothrix yaqonensis, has the potential to revolutionize several industries, including medicine, food safety, and environmental monitoring.
The discovery was made possible by engineering bacteria for technological applications, which include creating carbon-neutral biofuel and producing rocket fuel. However, finding a bacteria that can conduct electricity like a metal circuit is crucial for developing new generations of bioelectronics.
According to the research team, the electrically conductive bacteria are extremely rare and likely evolved to optimize their metabolic processes in sediment environments. The newly discovered organism possesses surface ridges up to three times wider than those found in similar species, which house highly conductive fibers of unique “nickel-based” molecules.
When an electrical current is applied, these fibers transport the current over long distances just like a wire. This property could inspire new bioelectronics and lead to innovative applications such as implantable devices and environmental cleanup.
The bacteria’s unique capability allows them to transfer electrons to clean up pollutants in sediments, making it a potential tool for removing harmful substances from contaminated areas. The discovery of Ca. Electrothrix yaqonensis is expected to bring about a new era for several industries and could lead to breakthroughs in bioelectronics and biomaterials.
The researchers’ findings demonstrate the potential of engineering bacteria for technological applications and highlight the importance of exploring the intersection of technology and biology.
