Schuler Receives $418,000 Grant to Harvest Energy from Bacterial Metabolism in Wastewater Treatment

Andrew Schuler

The Unites States Army Research Office has awarded Andy Schuler, asso­ciate pro­fes­sor of civil engi­neer­ing, a three-year, $418,000 grant to har­vest energy from bac­te­r­ial metab­o­lism in waste­water treatment.

Waste­water con­tains a vari­ety of waste com­pounds, which may con­tain two to three times the energy required for the treat­ment process itself. Micro­bial fuel cells rep­re­sent a devel­op­ing tech­nol­ogy in which bac­te­r­ial metab­o­lism is har­nessed to directly pro­duce an elec­tric cur­rent using “anode respir­ing bac­te­ria,” which deliver elec­trons to an anode in place of con­ven­tional res­pi­ra­tion, while simul­ta­ne­ously biode­grad­ing wastes.

The project, “Ratio­nal design of anode sur­face chem­istry in micro­bial fuel cells for improved exo­elec­tro­gen attach­ment and elec­tron trans­fer,” is being con­ducted through UNM’s Cen­ter for Emerg­ing Energy Tech­nolo­gies (CEET). This research will focus on fun­da­men­tal and applied research to develop mate­ri­als with engi­neered sur­face chemistries and other char­ac­ter­is­tics to improve elec­tron trans­fer from bac­te­ria to anode sur­faces, thereby improv­ing over­all per­for­mance and devel­op­ing this promis­ing source of renew­able energy.
