Conversion of waste CO2 into value-added chemicals by Microbial (Bio) electrosynthesis

Abstract: In the last decade, microbial electrosynthesis (MES) has gained increasing attention because of its abilities to produce biofuel or chemical precursors for a wide number of industries. By using renewable electrical energy, this bioelectrochemical system technology can convert gas waste streams containing CO2 into chemicals such as alcohols and carboxylic acids. This research aims to develop an optimised and integrated bioelectrochemically system capable of producing medium and longer chain carboxylates and their corresponding alcohols from CO2 at high yields and titers. Specifically, this project aims at will broadening the spectrum of products obtainable through MES by developing conditions that steer and predict the selective reduction of a desired product. The project will also advance novel electrode materials and mediators to improve product selectivity, yields and rates, and it will also develop effective methods for extraction of the produced chemicals. This research will significantly contribute to taking MES technology further into a commercially viable solution for converting waste CO2 into valuable products. This will, in turn, increase economy circularity whilst alleviating environmental damage.
