Sustainable production of high-value compounds using cyanobacteria
The project: Increasing environmental challenges means there is a need for novel, safe, sustainable and cost-effective production technologies. From this perspective production of chemicals using cyanobacteria is an attractive option. This is because cyanobacteria can be used to produce a range of compounds (e.g. polymers, vitamins, pigments and chemicals) using light and carbon dioxide as the main nutrients. Additionally, their fast growth rates and minimal nutrient requirements make them favourable from a scale-up perspective.
In order to further the use of cyanobacteria for sustainable production it is necessary to identify suitable strains.
Currently, the diversity of cyanobacteria and their potential for industrial application is yet to be fully explored, and a key aspect of this project would involve screening different species to identify the most promising for scale-up.
What you will be doing: this project will be primarily lab based. Students working on this project can:
- Cultivate a range of cyanobacteria species at small (< 250 mL) scales as well as at larger (3 L) scale using custom built photo-bioreactors.
- Learn skills about extraction of valuable compounds from biomass as well as their quantitation using HPLC and/or GC
- Work with cutting-edge automated bioreactor set-ups for strain characterisation and improvement.
- Learn skills in process development and optimisation.
- Develop skills in process scale-up, process modelling and techno-economic evaluation.
Work on the project is not limited to these areas – if you have an area you are particularly interested in please get in touch.
Applicants should have a First Class or Upper Second Class Honours degree, or a MSc in chemical engineering, biotechnology or a related discipline. Applicants should be able to work independently, have good written and oral communication skills and be self-motivated.

Meet the Supervisor(s)
- I joined the Chemical Engineering Department at Brunel University in May 2021, after moving from the University of Sydney where I was employed at the Centre for Advanced Food Engineering, working in the area of industrial biotechnology. Prior to that I completed my PhD at the University of Sydney in 2014 and my undergraduate degrees in Chemistry and Chemical Engineering in 2010.
My research is in the area of industrial biotechnology, with a focus on the safe, sustainable and cost-effective production of high-value compounds for the food, pharmaceutical and nutraceutical industries. A key focus of my work is sustainability and transforming what would be otherwise considered wastes to valuable products.
I have extensive experience in the design, scale-up and modelling of bioreactors, and have developed advanced computational models of industrial systems. I have worked extensively with industry and many of the projects I have worked on have been successfully commercialised.
