Algal Biosystems and Biotechnology


The Algal Biosystems Research Group aims to improve microalgal biomass productivity using a multidisciplinary approach.

Algal biomass may be used to produce: sustainable biofuels, bulk chemicals,  agriculture and aquaculture feedstocks, fertiliser, cosmetics, nutraceuticals and pharmaceuticals.

Algae may also be used in: carbon dioxide sequestration, wastewater treatment, solid waste treatment and desalination.

Research capacity

In order to bring mass-scale algal cultivation closer to reality, it is crucial to understand how abiotic environmental parameters influence algal physiology. We use a matrix of environmental photo-bioreactors (ePBRs) to address key commercialisation roadblocks. The ePBRs are used to simulate environmental conditions, such as irradiance, temperature and carbon availability, at prospective large-scale algal facilities within a controlled laboratory setting. Algal physiological response is measured in terms of chlorophyll fluorescence, oxygen evolution and biomass productivity. Using this approach it is possible to:

  • Assess algal biomass productivity with non-invasive optical technology,
  • Investigate the synthesis of various bio-products,
  • Optimise algal growth conditions,
  • Select the appropriate algal species for a specific environment, and
  • Anticipate and overcome obstacles to algal growth, such as photo-inhibitive irradiance levels or carbon limitation.

We are actively looking to explore opportunities for engagement with industrial and academic partners.
