Competition Funded PhD Project (European/UK Students Only)
Solar energy is our most abundant energy source and has enormous potential as a clean and economical energy supply. This PhD project will tap into this under-utilised source of power by engineering direct exchange of electrons between bacterial cells and inorganic photocatalysts for the biophotocatalytic production of solar chemicals such as fuels.
We have previously shown that the extracellular respiratory machinery of the bacterium, Shewanella oneidensis MR-1 (MR-1), can support direct exchange of solar energy (from synthetic photosensitisers) by transferring electrons across the bacterial outer membrane. In this project, you will use a novel synthetic biology approach to couple photocatalysts directly to this extracellular respiratory machinery. This will create biohybrid MR-1 assemblies that use intracellular redox transformations in vivo (metabolism) to sustain light-driven extracellular catalysis.
You will learn skills in expression, purification, reconstitution and functional characterization of (membrane) proteins and the characterization of photosensitisers, including nanoparticles such as quantum dots. Advanced biophysical characterisation techniques including life-time fluorescent spectroscopy, confocal microscopy, bioelectrochemistry and cryo-TEM will also be used. A range of biophysical techniques related to surface modification and bio-conjugation will be used the control the interaction between photosensitisers and respiratory proteins.
