In the murky mudflats of Oregon’s Yaquina Bay, researchers have uncovered a brand-new species of “cable” bacteria (Ca. Electrothrix yaqonensis) that literally acts like living wiring. These tiny powerhouses weave long, thread-like chains of cells studded with nickel-rich fibers—nature’s own nano–electrical conduits!
By shuttling electrons along these microscopic cables, they link deep, sulfur-rich layers of sediment with oxygen at the surface, effectively generating a natural current. This electron highway not only fuels their metabolism but also opens up exciting possibilities for environmental cleanup and next-generation bioelectronics.
What makes Ca. Electrothrix yaqonensis especially fascinating is its hybrid genetic makeup—a blend of traits from two other known cable-bacteria groups—which suggests it’s an evolutionary “bridge” offering fresh insight into how these organisms adapt across saltwater and freshwater habitats.
Under high magnification, its outer surface displays the most pronounced ridges yet seen in cable bacteria, beneath which lie the star of the show: nickel-based protein fibers that rival any synthetic conductor in their efficiency.
Nickel’s toxicity in humans is well documented, but in these bacteria it’s harnessed to perfection, enabling long-distance electron flow that could inspire bio-battery designs or pollution-fighting microbes.
Beyond pure curiosity, the real-world perks are enormous. As these bacteria can directly transfer electrons to environmental toxins, they hold promise for bioremediation—imagine deploying them to neutralize contaminants buried in sediments.
And their unique bio-conductors could guide scientists in building living electronics: self-assembling wires, biosensors powered by mud, or even “green” circuitry grown rather than manufactured.
“It stands out from all other described cable bacteria species in terms of its metabolic potential,” says postdoctoral researcher Cheng Li, highlighting how this new species could rewrite our understanding of microbial electricity.
And as we strive for cleaner technologies and smarter pollution solutions, the humble mudflat microbes of Oregon remind us that sometimes the smallest discoveries can spark the biggest revolutions.
