In situ microbial conversion of coal to methane: Biotechnology development for clean use of Australian coal. We will develop a biotechnology that uses native microorganisms to accelerate the underground conversion of coal to methane. Approximately 90% of Australia’s coal resources cannot be accessed economically using traditional mining technologies. A technology that converts coal to methane could generate an energy supply worth an estimated $60 billion, foster the development of an energy indu ....In situ microbial conversion of coal to methane: Biotechnology development for clean use of Australian coal. We will develop a biotechnology that uses native microorganisms to accelerate the underground conversion of coal to methane. Approximately 90% of Australia’s coal resources cannot be accessed economically using traditional mining technologies. A technology that converts coal to methane could generate an energy supply worth an estimated $60 billion, foster the development of an energy industry now in its infancy, and generate numerous new employment opportunities. Environmentally, methane is a cleaner burning fuel than coal, uses much less water for processing and generates the same quantity of electricity with lower CO2 emissions. This project highlights the fact that Australia’s microbial diversity is a resource we cannot afford to ignore.Read moreRead less

This project plans to use a newly discovered, low-cost and environmental benign antimicrobial agent to develop an innovative technology to control the development of corrosion-inducing sewer biofilms. Concrete sewer corrosion is a long-standing and costly problem for the water industry. Microbial hydrogen sulfide oxidation on concrete surfaces plays a critical role. The technology will be designed to prevent corrosion of new concrete sewers by adding a precursor chemical into the cement, or to slow down the corrosion of existing sewers by infrequently (once every one to few years) spraying the precursor chemical directly onto the concrete surface. Potentially, the project will substantially reduce sewer corrosion.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

Improving thiocyanate bioremediation with meta-genomics/transcriptomics. This project aims to elucidate the roles of thiocyanate-degrading microbial consortium members involved in sulphur and nitrogen oxidation, using metagenomics and metatranscriptomics. The gold mining industry generates environmentally toxic thiocyanate as a waste by-product, for which the most cost-effective remediation strategy is degradation by natural microbes. Efforts to bioremediate, however, suffer from a lack of understanding of the full metabolic potential of the microbes involved. The intended outcome of this project is the improved design and operation of thiocyanate bioremediation reactor systems.Read moreRead less
