Generate Key Takeaways A newly discovered bacterium wiggling about in the mudflats of the Oregon coast could advance a new era of bioelectric devices. It's been named Ca. Electrothrix yaqonensis, in honor of the First Nations Yaqo'n people local to the area it was found, and it conducts electricity just like a wire does. This is not unique, but Ca. Electrothrix yaqonensis has some fascinating traits of its own that set it apart from other conducting microbes. Collectively, these organisms are known as cable bacteria, and only a handful are known, split between two candidate (Ca.) genera that are yet to be cultured and formally described – Ca. Electrothrix and Ca. Electronema. They live in sedimentary environments, and arrange themselves, end-to-end, in long threads that transport electrons. The purpose of this is a division of metabolic labor between individual cells in the variably oxygenated environment in which they live. It's a true collective, as bacterial colonies often are, but in a manner uniquely suited to their murky, soggy home. Even among a peculiar set of species, though, Ca. Electrothrix yaqonensis stands out. "This new species seems to be a bridge, an early branch within the Ca. Electrothrix clade, which suggests it could provide new insights into how these bacteria evolved and how they might function in different environments," says microbiologist Cheng Li of Oregon State University and James Madison University. "It stands out from all other described cable bacteria species in terms of its metabolic potential, and it has distinctive structural features, including pronounced surface ridges, up to three times wider than those seen in other species, that house highly conductive fibers made of unique, nickel-based molecules." Led by microbiologist Anwar Hiralal of the University of Antwerp in Belgium, the researchers isolated and studied the bacterium using genomic, morphological, spectroscopic, and electrical characterization techniques. Their results revealed that it has some morphological differences from other cable bacteria, as well as genetic similarities to both genera. Among the most important findings were the pronounced ridges, as well as the extracellular sheaths the microbes exude when they form their long, connected strands. A filament of Ca. Electrothrix yaqonensis. (Oregon State University) These strands are how the bacteria perform reduction-oxidation reactions over long distances (up to several centimeters). The cells buried deeper in the sediment, where they can't access oxygen, create energy by metabolizing sulfide. This produces electrons, which they transport up to the oxygen-rich layer, where the upper cells use oxygen or nitrate to receive the electrons. This behavior, the researchers say, is something humans could tap into for purposes such as food safety and environmental cleanup. "These bacteria can transfer electrons to clean up pollutants, so they could be used to remove harmful substances from sediments," Li says. "Also, their design of a highly conductive nickel protein can possibly inspire new bioelectronics." Further work can help refine the position of this new species in the cable bacteria family tree, and what we can learn from it. "Its non-conformist metabolic traits highlight the complex evolutionary dynamics within the cable bacteria clade," the researchers write, "and suggest a broader functional and ecological diversity within this clade than previously recognized." The research has been published in Applied and Environmental Microbiology. Related News

'Bioelectric bacteria on steroids' could aid in pollutant cleanup and energy renewal
When you buy through links on our articles, Future and its syndication partners may earn a commission. A recently discovered species of bacteria is lighting up the scientific space. The organism is capable of conducting electricity effectively, almost like a cable wire. The bacteria could be used in the field of bioelectrics and also has the potential to help clean up pollution. A new species of bacteria has the ability to act as electric wiring, according to a study published in the journal Applied and Environmental Microbiology. Ca. Electrothrix yaqonensis is a cable bacteria, meaning it is "built from rod-shaped cells attached end to end," said Popular Mechanics. The bacteria's electrical conductivity is an unusual trait and is likely an "adaptation that optimizes their metabolic processes in the sediment environments in which they live," said a press statement about the study. While Ca. Electrothrix yaqonensis are not the only bacteria able to conduct electricity, they are considered "bioelectric bacteria on steroids," said Popular Mechanics. The species "stands out from all other described cable bacteria species in terms of its metabolic potential," Cheng Li, a postdoctoral researcher at Oregon State University and co-author of the study, said in the press statement. They have "distinctive structural features, including pronounced surface ridges, up to three times wider than those seen in other species, that house highly conductive fibers made of unique, nickel-based molecules." Specifically, the species is "transferring electrons along its body," and "shuttling charges through sediments in its environment," said BGR. The species also contains genes and metabolic pathways that are a mix of two different bacterial genera. "This new species seems to be a bridge, an early branch within the Ca. Electrothrix clade, which suggests it could provide new insights into how these bacteria evolved and how they might function in different environments," Li said. Ca. Electrothrix yaqonensis could be "ushering in a new era of bioelectronic devices for use in medicine, industry, food safety and environmental monitoring and cleanup," said the press release. "These bacteria can transfer electrons to clean up pollutants, so they could be used to remove harmful substances from sediments," said Li. This may be especially beneficial as remediation — defined as the act of reversing or stopping environmental damage — "can be one of the most time-consuming and costly aspects of infrastructure projects," said Popular Mechanics. "Particularly if a former brownfield site hopes to be reclaimed as a park or another public space." Using bacteria to clean up soil is a sustainable form of remediation because they are "made of proteins and self-replicating cells," said BGR. The applications of this bacteria go beyond pollution cleanup. Its discovery "expands our understanding of the genetic and morphological diversity of cable bacteria," said the study. The bacteria's nickel proteins can also "serve as a model for developing new materials in clean energy or sensor technology," said BGR. "Combined with other advancements in generating electricity — like with the Earth's rotation or by capturing energy from falling rain — this discovery could help power a new generation of renewable energy."

Scientists Have Just Discovered a New Type of Electricity-Conducting Bacteria
A new species of bacteria that functions like electrical wiring has recently been discovered on a brackish beach in Oregon. The species was named Candidatus Electrothrix yaqonensis in honor of the Yaquina tribe of Native Americans that once lived in and around Yaquina Bay, where the bacteria were found. This species is a type of cable bacteria: rod-shaped microbes that are connected at both ends to one another to create a chain and which share an outer membrane, forming filaments several centimeters long. Cable bacteria are found in marine and freshwater sediments and, unusually among bacteria, are electrically conductive. This is due to their special metabolism, in which electrons generated by oxidizing sulfides in their deeper layers are sent to their surface layer, where they are received by oxygen and nitric acid. The 25 species of cable bacteria known so far have been organized into two genera, Candidatus Electrothrix, which live in saltwater, and Candidatus Electronema, which live in fresh and brackish water. The new species discovered in this study has the genes and metabolic pathways of both the genera but is believed to be a bridge to an earlier branch of the Candidatus Electrothrix lineage, and so was classified as part of that genus. The recently discovered species may provide new insights into how cable bacteria evolved and how they can function in diverse environments, Cheng Li, a postdoctoral researcher at Oregon State University and coauthor of the research, explained in a statement. High Electrical Conductivity Candidatus Electrothrix yaqonensis is distinct from existing cable bacteria in its appearance. Cable bacteria have outer shells that feature ridges, which spread out like mountains. The ridges of the new species are much thicker than those of previously known species, reaching an average thickness of about 228 nanometers, up to three times thicker than what has been seen before. The new species' ridges are arranged in a spiral-like pattern on the surface of the filament, and their overall shape is more angular than that of other species. But the most striking difference is that the new species' filament is surrounded by a thick, transparent sheath. According to the authors of the paper outlining the discovery, this is a structure not previously seen. This sheath does not conduct electricity and is thought to protect the filament from the environment and foreign enemies.

Scientists discover a new organism that conducts electricity
Looks like scientists have found a new cousin to the eels! Well, not another eel , but a bacterium that can conduct electricity. And no, it doesn't zap, but it does work like biological wiring hidden in the mud. The findings are published in Applied and Environmental Microbiology . The novel species of bacteria act as electrical wiring, and could hold the potential to develop bioelectronic devices for use in medicine, industry, food safety, and environmental monitoring and cleanup. The researchers discovered the cable bacteria species in a mud flat at the Oregon coast and named it Ca. Electrothrix yaqonensis is named in honor of the Native Americans of the region where the species was found. Poll Would you support funding for further research on bioelectronic applications of bacteria? No Yes Cheng Li, who was a postdoctoral researcher at Oregon State University at the time of the research, and Clare Reimers, distinguished professor emerita in the OSU College of Earth, Ocean, and Atmospheric Sciences, identified the new species. Provided by Cheng Li The new cable bacteria have rod-shaped cells connected in a line, with a shared outer membrane, forming filaments that can reach several centimeters in length. Though conductivity is unusual among bacteria, this is an adapted process to optimize their metabolic processes in the sediment environments in which they live. The new organism shares similarities with the Ca. Electrothrix genus and the other known cable bacteria genus, Ca. Electronema, in terms of metabolic pathways and genes. 'This new species seems to be a bridge, an early branch within the Ca. Electrothrix clade, which suggests it could provide new insights into how these bacteria evolved and how they might function in different environments,' Li said. 'It stands out from all other described cable bacteria species in terms of its metabolic potential, and it has distinctive structural features, including pronounced surface ridges, up to three times wider than those seen in other species, that house highly conductive fibers made of unique, nickel-based molecules.' The fibers are responsible for the bacteria's ability to perform long-distance electron transport, linking oxygen or nitrate at the surface with sulfide deeper in the sediment. This ability to carry out chemical reactions over distance makes them important for sediment chemistry and nutrient cycling. 'These bacteria can transfer electrons to clean up pollutants, so they could be used to remove harmful substances from sediments.
