Solar energy is the most abundant energy source and can act as a green and sustainable energy supply. It is worth noting that one-hour sunlight can satisfy the one-year energy demand of the entire world. Artificial microbial photosynthesis is a novel strategy to produce value-added products from sunlight, microbes and CO2. The artificial photosynthetic system works by mimicking natural photosynthetic bio-machineries which can exceed the efficiency of natural photosynthesis. Light-harvesting materials and microbes are the essential components of this photo-biohybrid system. The proposed project tackles the largely unexplored challenge to develop highly efficient light-harvesting materials to maximize solar biofuel production through the innovative biohybrid system. The photo-electron activity of the microbes on the light-harvesting materials is fascinating as the materials can behave like electron sinks. Also, the proposed project will design a unique combination of photo-biohybrid system and fermentation process to produce medium-chain fatty acids (e.g. butyric acid) starting from CO2. In addition, the proposed design can make other exciting products such as medium-chain alcohols (e.g. butanol) by just tuning the microbial strains. The project will employ isotopic experiments, advanced spectroscopic techniques and OMIC tools to track the fundamental insights involved in the artificial microbial photosynthesis.
The following key skills will be gained during this project.
1. Microbiology: culturing of anaerobic microorganisms, microbial syntrophy, direct interspecies electron transfer, protein nanowires, protein extraction, RNA/DNA extraction, differential gene expression analysis
2. Materials Synthesis: semiconductors, quantum dots, 3D materials
3. Materials characterisation: electron microscopy, AFM, XPS, XRD, Raman
4. Analytical: GC, IC, HPLC, NMR
5. Reactor design: 3D printing
6. Electrochemical techniques: CV, DPV, LSV, chronoamperometry, EIS
We are looking to appoint a highly motivated PhD student to join the world’s first Hub for Biotechnology in the Built Environment (HBBE, http://bbe.ac.uk/
). This is a £8M initiative between Northumbria and Newcastle Universities funded by Research England. The Hub will develop biotechnologies to create a new generation of buildings which are responsive to their environment, grown using engineered living materials, metabolise their own waste, and modulate their microbiome to benefit human health. The Hub is a strategic expansion that will soon including 13 new academic staff, including Biologists, Architectural Designers and Engineers, supported by 5 PDRAs, 14 PhD students and 3 support staff. This will include 3 new research facilities that will integrate our research: the Micro Bio-Design Lab (Northumbria), the Macro Bio-Design Lab (Newcastle) and a unique Experimental ‘Living’ House, ‘The OME’.
Eligibility and How to Apply:
Please note eligibility requirement:
• Academic excellence of the proposed student i.e. 2:1 (or equivalent GPA from non-UK universities [preference for 1st class honours]); or a Masters (preference for Merit or above); or APEL evidence of substantial practitioner achievement.
• Appropriate IELTS score, if required.
For further details of how to apply, entry requirements and the application form, see https://www.northumbria.ac.uk/research/postgraduate-research-degrees/how-to-apply/
Please note: Applications should include a covering letter that includes a short summary (500 words max.) of a relevant piece of research that you have previously completed and the reasons you consider yourself suited to the project. Applications that do not include the advert reference (e.g. ET20/…) will not be considered.
Deadline for applications: 8th May 2020
Start Date: 1st Aug 2020
Northumbria University takes pride in, and values, the quality and diversity of our staff. We welcome applications from all members of the community. The University holds an Athena SWAN Bronze award in recognition of our commitment to improving employment practices for the advancement of gender equality.
