The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

How do nano-molecular carboxysome protein structures function in alpha and beta-cyanobacteria and can we use them for novel reaction compartmentalisation? In blue-green algae, protein nano-structures, known as carboxysomes, act as tiny compartments where carbon dioxide (CO2) can be fixed into simple sugars at high efficiency. This important photosynthetic process forms the basis of global primary productivity on this planet, but most land-based CO2 fixation lacks the efficiency seen in blue-gree ....How do nano-molecular carboxysome protein structures function in alpha and beta-cyanobacteria and can we use them for novel reaction compartmentalisation? In blue-green algae, protein nano-structures, known as carboxysomes, act as tiny compartments where carbon dioxide (CO2) can be fixed into simple sugars at high efficiency. This important photosynthetic process forms the basis of global primary productivity on this planet, but most land-based CO2 fixation lacks the efficiency seen in blue-greens. This research aims to determine how the proteins that make up carboxysomes are 3-dimensionally arranged and how these structures function to enhance rates of CO2 fixation. A more thorough understanding of the carboxysome is likely to have potential applications in industrial nano-technology and improve our understanding of oceanic primary productivity.Read moreRead less
Clean fuels for the future: Scale up and optimisation of microalgal oil production and biodiesel synthesis. The development of renewable carbon-neutral fuels is an urgent challenge facing our society. This project aims to develop an innovative system for biodiesel production from local Australian algae species. If cultivated under the right conditions, microalgae are very efficient near-continuous producers of biodiesel and are likely the only renewable source of fuel that could match our curren ....Clean fuels for the future: Scale up and optimisation of microalgal oil production and biodiesel synthesis. The development of renewable carbon-neutral fuels is an urgent challenge facing our society. This project aims to develop an innovative system for biodiesel production from local Australian algae species. If cultivated under the right conditions, microalgae are very efficient near-continuous producers of biodiesel and are likely the only renewable source of fuel that could match our current and future demand without competing for arable land and food production. Such systems couple the national/community benefits of energy generation, carbon-capture, biodiesel production and the clean-up of wastewater. Successful outcomes from this project will bring this innovative technology closer to commercial reality. Read moreRead less
Second generation biofuels: developing environmentally friendly high-efficiency microalgae for biofuel production. The development of CO2-neutral (biodiesel) and CO2-free (hydrogen) fuels is an urgent challenge facing our society to combat climate change and protect against oil price shocks.

The solar-powered microalgal systems being developed, offer a number of national/community benefits ....Second generation biofuels: developing environmentally friendly high-efficiency microalgae for biofuel production. The development of CO2-neutral (biodiesel) and CO2-free (hydrogen) fuels is an urgent challenge facing our society to combat climate change and protect against oil price shocks. Successful outcomes from this project will bring this innovative technology closer to commercial reality. The solar-powered microalgal systems being developed, offer a number of national/community benefits including
1. A high-efficiency frontier-technology for clean fuel production for the Australian and international market
2. A new process to desalinate water
3. Frontier technology to sequester atmospheric CO2
4. Frontier technologies for wealth generation in drought- or salinity-affected and naturally arid regionsRead moreRead less
Targeted bioengineering and systems biology for solar powered hydrogen production in green algal cells. The development of clean fuels to combat climate change and protect against oil price shocks, is an urgent challenge facing our society. Fuels make up ~67% of the energy market, yet most low-CO2 emissions technologies (e.g. nuclear and clean-coal-technology) target the electricity market. In contrast the Solar Bio-H2 process uses algal photobioreactors to drive solar-powered H2 fuel production ....Targeted bioengineering and systems biology for solar powered hydrogen production in green algal cells. The development of clean fuels to combat climate change and protect against oil price shocks, is an urgent challenge facing our society. Fuels make up ~67% of the energy market, yet most low-CO2 emissions technologies (e.g. nuclear and clean-coal-technology) target the electricity market. In contrast the Solar Bio-H2 process uses algal photobioreactors to drive solar-powered H2 fuel production from water (ultimately sea water, facilitating desalination). This project aims to improve the efficiency of the process towards economical levels. The Solar Bio-H2 process reduces water requirements for biofuel production. Locating bioreactors on non-arable land also eliminates competition between biofuel and food production.Read moreRead less
