Reactor Testing

First Lessons Learned: Control Reactors

In order to enhance the field-deployability of our final device, we initially decided to feed our reactors with LB, since a very concentrated LB source fed at a low flow rate could sustain our field reactors for extended periods of time without taking up much physical space. However, upon setting up control reactors—both in batch and continuous flow operation—we discovered that wild type S. oneidensis MR-1 produced significantly less current when fed with LB than M4—a commonly used media for Shewanella-inoculated bioelectrochemical systems.
