In recent years, bacterial power generation has become a hot topic, and scientists from the University of Tübingen in Germany have discovered that some bacteria found on the global seafloor and riverbeds can obtain electrons
from tiny metal particles.
By "donating" electrons to bacteria, iron particles become an efficient source
of energy for cells.
Other species of bacteria effectively breathe electrons by "puting" excess electrons
onto metal particles.
In addition, scientists have discovered that tiny magnetite grains, an ordinary magnetic mineral, can act as both an electron acceptor and an electron donor, thus working
effectively like a battery.
For bacterial communities, magnetite crystals function
like natural rechargeable batteries.
Depending on the needs of bacteria, magnets can be used as a conductor or as a "storage box" and source
of electrons.
