Description
Microbial fuel cells convert organic food waste into electricity via electrogenic bacteria.
Technical
In MFCs, mesophilic bacteria such as Geobacter and Shewanella oxidize food waste substrates, transferring electrons through outer membrane cytochromes to the anode. The electrons flow through an external circuit to the cathode, where they reduce oxygen or other electron acceptors, generating a measurable voltage. The process simultaneously reduces the chemical oxygen demand (COD) of the waste.
