Descripción del proyecto
Bacterias «eléctricas» para producir acetato a partir de dióxido de carbono
La electrosíntesis microbiana puede proporcionar productos químicos deseables a partir del dióxido de carbono y electricidad mediante la transferencia biológica de electrones. Esta característica podría ayudar a abordar los problemas de captura y almacenamiento de carbono para el sector de las energías renovables, y contribuir a una futura economía neutra en emisiones de carbono. El proyecto financiado con fondos europeos BioCat investigará los mecanismos fundamentales de la electrosíntesis microbiana en las proteínas de la membrana. La investigación utilizará distintas fuentes bacterianas para estudiar los mecanismos básicos de transferencia de electrones para la electrosíntesis. La fase final incluirá la construcción y la optimización de un prototipo operativo de reactor de funcionamiento continuo para la conversión del dióxido de carbono en acetato.
Objetivo
The project „BioCat“ investigates electron uptake mechanisms of electroactive bacteria catalyzing reduction processes on biocathodes at the protein membrane level. Thus, the project will significantly contribute to the basic understanding and optimization of
microbial electrosynthesis.
The driving force for the increasing interest in microbial electrosynthesis is the intriguing capacity of this technology to
produce high value chemicals from carbon dioxide and electricity. This conversion addresses carbon capture and storage
issues of renewable power sources and will contribute to a carbon neutral economy and society.
The project will be conducted at the Inorganic Biochemistry and NMR group (IBN) of the ITQB NOVA in Lisbon with a
secondment at the University of Tübingen at the Laboratory of Prof.Dr. Lars Angenent.
BioCat is divided into three main objectives. First of all a basic understanding of the role of c-type cytochromes and the
indirect or direct nature of the electron transfer will be investigated with Shewanella oneidensis. Subsequently Sporomusa
ovata and its membrane proteins carrying out electron transfer are studied, while the production of acetate from CO2 is
monitored. Both will be analyzed as a function of operating parameters (electrode potential and pH). To round up the project, an optimized continuous run prototype reactor will be operated and characterized.
The project will enable the researcher Joana Madjarov to get trained in the whole chain of basic to applied research. The
main focus lies in the fundamental biochemical research, but the project directly links the findings to application relevant acetate production yields and efficiency.
