Harvesting bacteria electric impulse

Bacteria

Geobacter and Shewanella have different mechanisms

In microbial fuel cells (MFCs), bacterial nanowires generate electricity via extracellular electron transport to the MFC's anode.

The currency produced by bacterial nanowires very low. Current density of around 17 microamperes per square centimeter, voltage of around 0.5 volts across a 7-micrometre-thick film...

Above is the work of one of the iGem teams from 2020, they transformed the E.coli to have the Geobacter sulfurreducens prosperities.

When the nerve impulse from brain and spinal cord are carried along motor neuron to neuromuscular junction, Ca++ ions are released in the terminal axon. Increases calcium ion concentration stimulates the release of neurotransmitter (Acetylcholine) in the synaptic cleft. The neurotransmitter binds to the receptor on the sarcolemma and depolarization and generate action potential across muscle fiber for muscle contraction. The action potential propagates over entire muscle fiber and move to the adjacent fibers along transverse tubules. The action potential in transverse tubules causes the release of calcium ion from sarcoplasmic reticulum, which stimulate for muscle contraction.

Bioremediation of uranium contaminated groundwater. Clearing ground. Nanowire present strains are more effective at the mineralization of uranium as compared to nanowire absent mutants.

bioelectronics (possibility) - scientists have proposed the future use of biofilms of Geobacter as a platform for functional under water transistors and supercapacitors, capable of self-renewing energy.
