[Translate to English:] Illustration of the idea behind BIOMAP. Cable bacteria transport electrons over centimeter distances, connecting a sulfide oxidizing reaction with an oxygen reducing reaction, which results in electric potential differences in the environment. This has been shown in sea and lake sediment, and if cable bacteria in a similar way connect the chemical energy in a patch of soil pollution with the oxygen in the soil above, electric potential differences can be detected on the soil surface. This idea is supported by pilot experiments and the BIOMAP consortium will turn the idea into a new cheap and non-intrusive method for soil pollution mapping. (Illustration: Lars Riis Damgaard)

[Translate to English:] Electric bacteria will show the way to soil contamination

[Translate to English:] In a new collaborative project called BIOMAP, researchers, the business community and government agencies and institutions will utilize electrical signals from soil bacteria to map soil-contaminated sites in Denmark. The Innovation Fund Denmark has invested nearly 12 million DKK in the project, which is intended to make…

Our aim

No one had ever imagined life based on internal electric wires.

Cable bacteria conduct electrons with an efficiency that physics and molecular biology so far can’t explain, and nothing is known on how they control their energy and growth metabolism, when the respiratory electron transport chain is split between cells centimeters apart.

Center for Electromicrobiology aims to unravel how this unique form of life functions.
