"Electrical energy from the socket - this convenient type of power supply is apparently used by some microorganisms. Cells can meet their energy needs in the form of electricity through nanowire connections. Researchers from the Max Planck Institute for Marine Microbiology in Bremen have discovered these possibly smallest power grids in the world when examining cell aggregates of methane degrading microorganisms. They consist of two completely different cell types, which can only jointly degrade methane. Scientists have discovered wire-like connections between the cells, which are relevant in energy exchanges."
Electrical energy from
the socket - this convenient type of power supply is apparently used by
some microorganisms. Cells can meet their energy needs in the form of
electricity through nanowire connections. Researchers from the Max
Planck Institute for Marine Microbiology in Bremen have discovered these
possibly smallest power grids in the world when examining cell
aggregates of methane degrading microorganisms. They consist of two
completely different cell types, which can only jointly degrade methane.
Scientists have discovered wire-like connections between the cells,
which are relevant in energy exchanges.

Archaea (red) yield eight electrons from the oxidation of a single methane molecule. The electrons travel via the nanowires to the sulphate reducing bacteria (green). The bacteria use those electrons to convert one molecule sulphate into hydrogen sulphide. Credit: MPI f. Marine Microbiology
Electron micrograph of the nanowires shows connecting archaea and
sulphate reducing bacteria. The wires stretch out for several
micrometres, longer than a single cell. The white bar represents the
length of one micrometre. The arrows indicate the nanowires
(A=ANME-Archaeen, H=HotSeep-1 partner bacteria). Credit: MPI f.
