| Resumo: | Microbial Electrochemical Technologies (METs) are a promising alternative for capturing and in-situ reducing CO2 through the use of renewable electricity. Microorganisms grown in autotrophic conditions use CO2 as an electron acceptor and an electrode provides them electrons in the form of electricity. In this process, known as microbial electrosynthesis (MES), different compounds are produced depending on the metabolic possibilities of the microorganisms present in the system. The potential of this technology is high: a culture enriched with selected electroactive microorganisms is able to effectively transform CO2 into high value-added compounds. This Doctoral Thesis investigated reliable operational procedures for the monitoring of the performances of METs to produce suitable substrates for economically viable downstream applications. The cathodes of two different designs of bioelectrochemical systems (BESs) were inoculated with an enriched culture of a carboxydotrophic strain and were operated until stable conversion of CO2 into acetate, ethanol and small amounts of butyrate. |
