Overview

Since the European Jamboree in Lyon we have been busy and continued working on our project. We managed to create serveral devices by different combinations of the mediator producing parts and the outer membrane porin, did some modelling on the maximal yield of glycerol as a carbon source and conducted additional measurements with our MFC. We even printed a car that should be powered by our MFC.

Genetic Optimization

• In order to test the effect of the protein expression of the outer membrane porin OprF and the glycerol dehydrogenase GldA on the cell growth, growth was measured as increase in optical density and plotted against time.

• We constructed new devices by combination of the mediator producing parts (riboflavin synthesis gene cluster and glycerol dehydrogenase) with the outer membrane porin OprF.
