The broad goal of our project was to engineer s. Odenisis to produce a detectable change in electric current in response to some environmental stimulus. In order to observe such a reaction, our first task was to design an environment capable of housing bacteria and measuring current production.

Solution - Microbial Fuel Cells


Microbial Fuel Cells (MFCs) are devices that use bacteria as the catalysts to oxidize organic and inorganic matter and generate current <ref></ref>. They have been used by researchers to study the mechanisms involved... The principle behind these devices is to physically separate the oxidation and reduction reactions, creating an electrical path between


Design Goal

 Functional description

The final product is a complete system capable of introducing separate strains of bacteria to multiple different environments while simultaneously measuring and recording current readings from each. The experimenter specifies the number of bacteria/environment combinations to be run, as well as the initial conditions for each. Data collection and storage is automated, with a computer displaying live current readings and graphing historical current levels. The experimenter can change the conditions of any environment throughout the course of the experiment without affecting other environments. The environments themselves are stand-alone, capable of being treated as individual circuit components.
