DDE (2,2-bis (p-chlorophenyl)-1,1-dichloroetylene) is a very persistent and bioaccumulative pesticide and its residues are continuously found in the environment. Among the green remediation strategies for soil recovery, terrestrial Microbial Fuel Cells (MFC) are arousing great interest in scientific community. MFCs transform energy stored in the chemical bonds of organic compounds into electrical energy thanks to exo-electrogen microorganisms naturally occurring in soil, which catalyse oxidation and reduction reactions in the area between two graphite electrodes.

This paper talks about an original hardware project of a measuring instrument dedicated to microbial fuel cells (MFCs) electrical characterization and valorizations. MFC is a promising energy harvesting technology with zero carbon emission[1], which can produce suitable energy for low power electronic devices for application like wireless sensor network (WSN)[2] for ambient monitoring or precision agriculture.
