Electrochemical Activity of Bacterial Species in a Microbial Fuel Cell

CSEF · 2026 Environmental Engineering (Track 2) (Junior Division)

Luz de Luna Gomez

Overview

A Microbial fuel cell is a bio-electrochemical device that can convert organic waste into electricity. MFCs using organic waste do not produce enough power to meet energy demands. In this experiment, I tested what bacteria was the most effective in a MFC, B.subtilis, E.coli or A. tumefaciens? The results of this experiment showed that B.subtilis and A.tumefaciens produced more energy than E. coli. In comparison to organic waste MCFs my fuel cell generated around 40 mV more. This research can be used to improve the development of MCFs in the future.
