Welcome to the wiki for the 2017 iGEM team of the University of Southern Denmark! Our project this year focuses on green energy through bioelectricity in the form of a bacterial solar battery. This device will be constructed to contain two cultures of genetically engineered Escherichia coli (E. coli). A photosynthesising E. coli will produce a carbon source in the form of cellulose, by fixating carbon dioxide through Calvin Cycle and harvesting energy from sunlight . When switched on, the second E. coli will break down the formed cellulose by secreting cellulase through the cellulase secretion system. Once cellulose is broken down, cellobiose can enter the second E. coli and be broken down to glucose by introduction of periplasmic beta-glucosidase. Electrons will then be harvested from the anaerobic glycolysis of glucose to facilitate an electrical current. The electron transfer will be mediated by bacterial nanowires retrieved from Geobacter sulfurreducens.
Our device will be designed to resemble a leaf, in which way it can contribute to a better city ambience when integrated into an urban environment. For the implementation of our device in an urban environment, we will collaborate with city planning experts, with focus of implementation of our device into our home city, Odense. This way, our device can be optimised to reach its full potential and thereby fulfill the needs for a greener future.
Plant leaves do photosynthesis and are full of bacteria. Our leaf is just like that - except it also powers your phone!
