A miniaturized parallel analyses platform for rapid electrochemical discoveries of microbial activities

We report a nine-well MEMS-based parallel analyses platform for testing electricity generation capacity of eight microbial consortia, which provides high throughput characteristics for bacterial electrogenic screening. The presented device features independent fluidic access to each analysis unit allowing for long term analysis ability without contamination from chamber to chamber during operation. The device contains vertically stacked 57μL anode/cathode chambers separated by a proton exchange membrane (PEM) and each device component is thermally assembled without mechanical supporting frames/bolts/nuts. This device will create a compact screening system individually addressable for identification and characterization of electrochemically active microbes.
