Biogeochemical remediation approaches for PFAS contaminated environments. This project aims to identify and harvest microorganisms capable of directly or indirectly affecting PFOS or PFOA degradation in the environment. Fluorinated compounds such as PFOS and PFOA in firefighting foams are contaminants of concern now routinely detected in contaminated groundwater and soil globally.

Fluorinated compounds such as PFOS and PFOA in firefighting foams are contaminants of concern now routinely detected in contaminated groundwater and soil globally. Understanding the role of microorganisms, and the biogeochemical processes they perform in relation to fluorinated compounds, will inform handling of contaminated sites and lead to development of cost effective and sustainable remediation technologies.

The findings of the project will demonstrate the fundamental mechanisms behind botanical air pollutant biofiltration, apply systematic technological development against a range of air pollutants, and provide strategies to deploy the technology. With a transdisciplinary approach utilising techniques new to this discipline, the project will substantially advance the fundamental science underlying this novel and highly valuable area of air-bioremediation technology, and will create a much stronger economic driver for this Australia-led innovation.Read moreRead less

Electron transfer at the microbe-mineral interface via cytochromes/exudates. This project aims to develop the kinetic (both in vivo and in vitro) and thermodynamic models of the extracellular electron transfer processes at the microbe-mineral interface via outer membrane cytochromes and exudates of dissimilatory iron-reducing bacteria, and elucidating the potential electron transfer process from iron-reducing bacteria to semiconducting iron minerals. The observed models will provide a more compr ....Electron transfer at the microbe-mineral interface via cytochromes/exudates. This project aims to develop the kinetic (both in vivo and in vitro) and thermodynamic models of the extracellular electron transfer processes at the microbe-mineral interface via outer membrane cytochromes and exudates of dissimilatory iron-reducing bacteria, and elucidating the potential electron transfer process from iron-reducing bacteria to semiconducting iron minerals. The observed models will provide a more comprehensive understanding of electron transfer reactions at the microbe-mineral interface, which will be helpful in the prediction of natural redox processes of iron transformation and in the development of bioremediation strategies for contaminated sites.Read moreRead less
Electron transport catalysis in organohalide pollutant respiration. This project aims to understand the link between substrate specificity and gene sequence of dehalogenating enzymes in organohalide respiring bacteria (ORB) and the mechanism by which electrons are transferred to dehalogenating enzymes through protein-protein interactions. Organohalides were present in Earth's early history and now pollute the environment globally. Organohalide respiring bacteria (ORB) can degrade these pollutant ....Electron transport catalysis in organohalide pollutant respiration. This project aims to understand the link between substrate specificity and gene sequence of dehalogenating enzymes in organohalide respiring bacteria (ORB) and the mechanism by which electrons are transferred to dehalogenating enzymes through protein-protein interactions. Organohalides were present in Earth's early history and now pollute the environment globally. Organohalide respiring bacteria (ORB) can degrade these pollutants by using them as terminal electron acceptors in their respiratory metabolism. This represents one of the most ancient respiratory systems on Earth about which little is known. This project will add to our fundamental knowledge of microbial evolution and metabolic systems, and pave the way for next generation organohalide remediation technologies.Read moreRead less

Summary
Three-dimensional analysis of important organic components in energy, environmental and earth systems. Australia’s ecosystems and water resources are sensitive to climate change and anthropogenic activities. A third degree of separation provided by this technique will improve our abilities to monitor the role of organic matter in modern systems. The characterisation of organics of petroleum mineral systems will sustain Australia's energy demand.

This project aims to develop an integrated prefabricated building panel solution combining green wall and hempcrete technology to address environmental problems associated with the usage of carbon intensive construction materials, dense urbanisation, climate change and biodiversity. Innovation in hempcrete technology consist in using low carbon options including alkali-activated binders and biomineralization technology, glass waste replacing natural sand. Hempcrete green wall panels will be design to be carbon positive, improve the thermal performance of buildings, provide better acoustic insolation, reduce the risk of mould proliferation, control indoor humidity and air quality and improve indoor thermal comfort.

Accelerated tailings remediation with plant and microbial biotechnologies. The Australian alumina industry produces 32 million tonnes of bauxite residue (alumina refining tailings) each year, most of which is stored in perpetuity in landfill-type tailings storage facilities. The high pH, high salinity, lack of plant nutrients, and poor physical properties of bauxite residue are major barriers to safe storage and successful closure of tailings storage facilities.

The Australian alumina industry produces 32 million tonnes of bauxite residue (alumina refining tailings) each year, most of which is stored in perpetuity in landfill-type tailings storage facilities. The high pH, high salinity, lack of plant nutrients, and poor physical properties of bauxite residue are major barriers to safe storage and successful closure of tailings storage facilities. Existing remediation approaches are expensive, slow, and often ineffective. We will deliver new microbial- and plant-driven biotechnologies for rapid, cost-effective remediation of bauxite residue. This will enable safe, sustainable closure of storage facilities, and safeguard the strong contribution of this $15 billion industry to Australia's economy. Read moreRead less
Exploiting natural processes to effectively remediate acidified coastal environments. Working with local government, industry and communities, this project aims to identify how natural processes can best be manipulated to limit acid sulfate soil discharge in many Australian estuaries. The expected outcomes are systematic remediation of these areas and improvement in estuarine water quality.
