Biocathode metaproteomics - A previously uncharacterized, non-photosynthetic member of the Chromatiaceae is the primary CO2 fixing constituent in a self-regenerating biocathode

This project focust on proteogenomic characterization of a robust low complexity biocathode community which was enriched from, and cultivated on, the cathode of a microbial solar cell (MSC). This consortium forms a multi-cell layer thick biofilm on the poised electrode surface (+310 mV SHE) and can directly use electrical current as an electron donor to fix CO2 and reduce O2.
