Накратко на български

Микробната електросинтеза превръща въглеродния диоксид в полезни химикали, като използва специални електроди и глицерол за захранване на процеса. Това помага за намаляване на парниковите газове и превръщата отпадъчните материали в устойчиви ресурси.

Bioelectrochemical transformation of CO2 for the synthesis of value-added products

The BIOELECTRO-CO2 project addresses the urgent need for innovative solutions to mitigate greenhouse gas emissions, particularly CO2. With greenhouse gases on the rise, this project focuses on reducing CO2 emissions through microbial electrosynthesis (MES), a technique utilizing microorganisms to convert chemical waste into sustainable chemical commodities. Unlike conventional MES systems that rely on bicarbonate (due to the low solubility of CO2 in water), the BIOELECTRO-CO2 project has developed an advanced approach that directly uses CO2 as a feedstock by implementing a dual bio-catalyzed MES system. A key innovation is the use of gas diffusion electrodes (GDEs) to enhance CO2 uptake, overcoming the problem of its low solubility in water. Another key feature is the integration of a specially designed biocatalyzed anode that oxidizes glycerol, a byproduct of biodiesel production, to generate energy for the MES system while producing valuable chemical byproducts. This dual functionality not only maximizes resource use but also adds significant sustainability benefits by converting waste materials into useful products. By advancing CO2 reduction technologies and encouraging renewable chemical production, BIOELECTRO-CO2 has the potential to make a meaningful contribution to climate change mitigation and sustainable resource transformation at scale.

Цел на проекта

The on-going climate crisis and accelerating production of greenhouse gases such as carbon dioxide has sparked a sense of urgency in the scientific community to come up with solutions to sequestrate and/or recycle CO2. CO2 is a rather stable molecule that needs a high energy input to be chemically activated, and applications to utilize CO2 effectively are still in their infancy, with several research gaps that need to be filled. In this proposal we will use a new biotechnology named microbial electrosynthesis (MES) that has the ability to use a number of aqueous and gaseous wastes, including CO2, and biotransform them into useful chemical commodities. In order to use MES for practical and large-scale applications, utilization of CO2 from exhaust gases should be the target. We will fabricate and use gas-diffusion electrodes (GDEs) enabling microbial catalysts to take up CO2 gas directly and more efficiently, solving the problem of low CO2 solubility in aqueous media and mass transfer limitations. This project will develop a novel dual biocatalyzed MES consisting of an efficient gas diffusion biocathode for CO2 sequestration in combination with a bioanode for simultaneous product valorization from glycerol, using different biocatalysts, including enriched and engineered synthetic communities. The use of microbial catalysts both at the anode and cathode will significantly increase efficiency and product specificity of the MES system, which is low with chemical catalysts. Furthermore, the application of a bioanode based on oxidation of a cheap industrial by-product such as glycerol, not only generates higher energy electrons for the GDE biocathode saving energy, but also leads to production of added value compounds, making the process more energy and cost efficient.
