SYNENERGENE/ Applications

Our project

Ecological power management is currently facing three challenges: the storage of electrical power, the development of renewable energy resources, which are not timely and locally synced with demand, and the increase of atmospheric carbon dioxide due to the use of fossil fuels. We address these challenges by implementing a proof of concept production of the biofuel isobutanol from carbon dioxide. In our project, a bacterial microcompartment from cyanobacteria, the carboxysome, was deployed in Escherichia. coli for carbon dioxide fixation under aerobic conditions. We further engineered E. coli to derive the energy for this process from electricity by implementing electron-mediator uptake and recycling. This ‘electricity’ pathway comprised proteins such as the furmarate reductase. Feasibility was analyzed in a self-constructed bioreactor. Ultimately, we established an isobutanol production pathway by heterologous expression of five genes from E. coli, Bacillus subtilis and Lactococcus lactis.

 <p>
-The supply with electricity is facing three major problems: the storage of electricity, the increasing amount of atmospheric carbon dioxide and the development of alternative energy sources. Therefore we want to implement a proof of concept for the production of the biofuel isobutanol from carbon dioxide. A bacterial microcompartment originated from cyanobacteria, called carboxysome, is used to realize the fixation of carbon dioxide in <i>Escherichia coli</i>. Within this microcompartment the carbon dioxide fixation is enabled under aerobic conditions. The needed energy for this process is provided by electricity. The electrons are transferred with a mediator into the cells and its uptake is empowered by different modifications of <i>E. coli</i>, like over-expression of the fumarate reductase. This concept is realized in a self-constructed bioreactor. Finally the production of isobutanol is established by hetereologous expression of various enzymes from different species.</p><br>
