Abstract
“Biocathode MCL,” designated for its main bacterial constituents (Marinobacter, Chromatiaceae, and Labrenzia), is a stable microbial community enriched from seawater that forms biofilms on the surfaces of electrodes. These biofilms are effective to perform carbon fixation without the need for external electrical power nor sunlight applied thereto.
Claims4
An apparatus for studying electroautotrophy, comprising:
- a reactor vessel containing natural or artificial seawater;
- an unpoised working electrode immersed in the seawater;
- a reference electrode immersed in the seawater;
- a counter electrode immersed in the seawater;
- and an electroautotrophic biofilm living attached to the working electrode, wherein the biofilm comprises Ca. Tenderia electrophaga.
