Summary
A transportable containerised laboratory for rapid cell sorting and high-resolution bioimaging of living aquatic microbes in field locations. This project will deliver a transportable, unique laboratory for the rapid isolation and high-resolution analysis of living microbes immediately after sampling from the sea or waterways. It will be the first of its kind in Australia and deliver new knowledge of the role of these organisms in their natural habitats.
Eco-engineering soil from mine tailings for native plant rehabilitation. Eco-engineering soil from mine tailings for native plant rehabilitation.

Eco-engineering soil from mine tailings for native plant rehabilitation. This project aims to develop integrated and low-cost eco-engineering technology to purposefully accelerate in-situ formation of soil from tailings for sustainable native plant community rehabilitation at metal mines. Soil shortages at mines cost the Australian mining industry billions of dollars in sustainable rehabilitation of tailings, and threaten the industry’s ecological and commercial sustainability. Building on recent findings of critical processes in soil formation from copper/lead–zinc tailings, this research will use key biogeochemical and rhizosphere processes in the tailing-soil to create a functional 'technosol'. This technology is intended to be used in Australian metal mines to offset the soil needed to rehabilitate tailings landforms with native plant communities.Read moreRead less
In situ remediation in mine site rehabilitation. In situ remediation in mine site rehabilitation. By enhancing and guiding abiotic and biotic processes of soil development, this project aims to accelerate the in situ remediation of bauxite residue (alumina refining tailings). Over 7 gigatonnes of tailings are produced globally every year, comprising complex mineral assemblages at extremes of pH and salinity with minimal biological activity. This project will build detailed knowledge on the chemi ....In situ remediation in mine site rehabilitation. In situ remediation in mine site rehabilitation. By enhancing and guiding abiotic and biotic processes of soil development, this project aims to accelerate the in situ remediation of bauxite residue (alumina refining tailings). Over 7 gigatonnes of tailings are produced globally every year, comprising complex mineral assemblages at extremes of pH and salinity with minimal biological activity. This project will build detailed knowledge on the chemical, physical, and biological properties of bauxite residue and apply this to develop field-scale in situ remediation strategies. This research will also advance understanding of soil development and primary succession of microbial communities in extreme, anthropogenic environments such as those presented by tailings.Read moreRead less
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. Existing remediation approaches a ....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. 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
The connectivity of pore theory - does it influence microbial community composition and function? Climate change scenarios indicate that Australia will be directly affected by an increase in greenhouse gas emissions. Soil microbial activity is responsible for a large proportion of such emissions; therefore it is important that we understand how such changing climate patterns are likely to influence key microbial populations in soil, particularly those involved in the production of greenhouse ga ....The connectivity of pore theory - does it influence microbial community composition and function? Climate change scenarios indicate that Australia will be directly affected by an increase in greenhouse gas emissions. Soil microbial activity is responsible for a large proportion of such emissions; therefore it is important that we understand how such changing climate patterns are likely to influence key microbial populations in soil, particularly those involved in the production of greenhouse gases. This research interfaces two disciplines, earth and biological sciences, and will establish a new international collaboration that will ensure Australia is at the forefront of a rapidly developing research field.Read moreRead less
Identifying limitations to the establishment of microbial communities and sustainable nutrient cycling in bauxite residue sand under rehabilitation. Australia is the world's largest producer of bauxite. The process of refining bauxite to aluminium generates 2 t of residue for every 3 t of bauxite, creating a major residue management issue. Rehabilitation of residue disposal areas is critical for reducing impacts on the environment and surrounding community and ultimately aims to create a sustain ....Identifying limitations to the establishment of microbial communities and sustainable nutrient cycling in bauxite residue sand under rehabilitation. Australia is the world's largest producer of bauxite. The process of refining bauxite to aluminium generates 2 t of residue for every 3 t of bauxite, creating a major residue management issue. Rehabilitation of residue disposal areas is critical for reducing impacts on the environment and surrounding community and ultimately aims to create a sustainable ecosystem following closure of the facility. This research will provide a detailed understanding of the establishment of microbial communities and the factors controlling the survival and functioning of microorganisms in bauxite residue sand. The outcomes will aid the development of improved protocols and strategies for bauxite residue rehabilitation in Australia and internationally.Read moreRead less

Summary
High resolution liquid chromatography mass spectrometry (Orbitrap) for analyses of polar compounds in biomass, petroleum, potable and reclaimed water. Climate change and human impact can harm sensitive ecosystems, significantly threatening Australian biodiversity and water resources. Chemical and biological characterisation of aquatic and terrestrial environments is paramount to assessing and responding to these threats, as well as assisting natural resource utilisation.

Climate change and human impact can harm sensitive ecosystems, significantly threatening Australian biodiversity and water resources. Chemical and biological characterisation of aquatic and terrestrial environments is paramount to assessing and responding to these threats, as well as assisting natural resource utilisation. The high structural polarity of many environmentally occurring organics from biological, petroleum and anthropogenic sources, unamenable to gas chromatographic resolution, can now be accommodated by the advanced organic analytical technology sought in this proposal. This project will enable scholars and young professionals to be skilled in state-of-the-art technology, and prepare quality scientists, ready for employment.Read moreRead less
