Continuous acetate production through microbial electrosynthesis from CO2 with microbial mixed culture

Microbial electrosynthesis represents a promising approach for renewable energy storage in which chemically stable compounds are produced using CO2 as feedstock. This report describes the continuous production of acetate through microbial electrosynthesis from CO2 and assesses how the production rat...

This report describes the continuous production of acetate through microbial electrosynthesis from CO2 and assesses how the production rates could be increased. RESULTS: A continuous acetate production rate of 0.98mmol C LNCC-1 d-1 was obtained using CO2 as feedstock and with pH control around 5.8. These conditions increased substrate availability and favoured microbial electrosynthesis. Cyclic voltammograms demonstrated the electroautotrophic activity on the biocathode surface, which increased with pH control and caused current demand and acetate production rate to rise exponentially. CONCLUSION: pH decrease was shown to be an effective strategy to increase substrate availability and enhance microbial electrosynthesis. By making microbial electrosynthesis a feasible technology, CO2 could become an alternative feedstock for the carboxylate platform. © 2015 Society of Chemical IndustryThis research was supported financially by the Spanish Government (CTQ 2011–23632, CTQ 2011–24114)WileyMinisterio de Ciencia e Innovación (Espanya)infoinfo2016info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://hdl.handle.net/10256/13784http://hdl.handle.net/10256/13784© Journal of Chemical Technology and Biotechnology, 2016, vol. 91, núm. 4, p. 921-927Articles publicats (D-EQATA)reponame:Recercat.
