Scientists Have Just Discovered a New Type of Electricity-Conducting Bacteria
A new species of cable bacteria, which function like electrical wiring, was recently discovered in the US. Its unique morphology and genetic structure may be useful for the development of bioelectronics.
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. 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. Candidatus Electrothrix species, which live in saltwater, typically use an electron-transfer enzyme called “sodium-transporting NADH-quinone oxidoreductase (NQR)” to regulate osmotic pressure.
