The aim of the project is to examine structural and functional microbiome dynamics in an ecologically important coral on the Great Barrier Reef along a natural temperature gradient. Microorganisms form an intimate symbiotic relationship with corals and are critical to their health. However, the microbiome can be disrupted by environmental perturbations, including higher-than-normal ocean temperatures, leaving the coral susceptible to disease and bleaching. Currently, our understanding of how the microbiome composition and metabolic function change in response to seasonal temperature variation and disease is limited. This project is designed to provide insight into the role the microbiome plays in maintaining coral health and may aid in the long-term preservation of the reefs.Read moreRead less
Illuminating the microbial world using genome-based fluorescence microscopy. Our understanding of microbial diversity on Earth has been fundamentally changed by metagenomic characterisation of natural ecosystems. Traditional approaches for visualising microbial communities are time-consuming and provide limited information about the identity of specific microorganisms.

Our understanding of microbial diversity on Earth has been fundamentally changed by metagenomic characterisation of natural ecosystems. Traditional approaches for visualising microbial communities are time-consuming and provide limited information about the identity of specific microorganisms. The proposed research aims to combine single cell genomics and super resolution microscopy for novel, high-throughput, genome-based techniques to visualise microorganisms, plasmids and viruses, with strain level specificity. The application of these highly scalable approaches will provide comprehensive and unprecedented insight into the fine-scale dynamics and evolution of environmentally and biotechnologically important microbial communities.Read moreRead less
A functional genomic approach for understanding metal ion adaptation in marine cyanobacteria. Unicellular marine cyanobacteria constitute 20-40% of total marine chlorophyll biomass and carbon fixation, and hence significantly impact the global carbon cycle and are very relevant to combating global warming. This research will reveal some of the major mechanisms by which marine cyanobacteria have adapted to metal levels in coastal and oligotrophic environments. Thus these results will help us und ....A functional genomic approach for understanding metal ion adaptation in marine cyanobacteria. Unicellular marine cyanobacteria constitute 20-40% of total marine chlorophyll biomass and carbon fixation, and hence significantly impact the global carbon cycle and are very relevant to combating global warming. This research will reveal some of the major mechanisms by which marine cyanobacteria have adapted to metal levels in coastal and oligotrophic environments. Thus these results will help us understand the distribution and diversity of these organisms in relation to global primary productivity. They will also lead to the development of more robust biomarkers for metal stress and pollution in coastal environments.Read moreRead less
Microbial sulphatises in the rhizosphere and their control by interactions with plants. Plant-microbe interactions are critical in mobilizing soil sulphur for crop growth. This project will identify the microbes responsible for delivering sulphur to two major Australian crops, and will examine how the plants stimulate this activity in their root zone. The results have potential application for sustainable agriculture in Australia.
Geobiological gold cycling: Golden opportunities for the minerals industry. This project aims to develop new geobiological tools for gold exploration and processing that are rooted in a fundamental understanding of geobiological gold cycling. Given the high production costs, the sustainability of the Australian gold industry relies strongly on innovation. Yet, there are many gaps in our fundamental understanding of bio (geo)chemical gold dispersion and precipitation.

This project aims to develop new geobiological tools for gold exploration and processing that are rooted in a fundamental understanding of geobiological gold cycling. Given the high production costs, the sustainability of the Australian gold industry relies strongly on innovation. Yet, there are many gaps in our fundamental understanding of bio (geo)chemical gold dispersion and precipitation. This project aims to fill these gaps by linking biochemical pathways of gold mobilisation and resistance in bacteria to its transport and biomineralisation. This would enable the development of protein-based biosensors, bioindicators and nanovectors. These would support the development of exploration and bioaccumulation technologies that allow more economically sustainable and environmentally viable mining practices, such as enhancing production from subeconomic ore.Read moreRead less
Changing the classification status quo with a global genome-based taxonomy. A grand challenge in biology is the reconstruction of the complete evolutionary history of life on our planet. A major hurdle to this goal has been the inability to culture most microbial species which comprise the bulk of evolutionary diversity. However, new molecular techniques have removed this hurdle and >1,000 new microbial species are being revealed each month through sequencing of environmental samples. This proje ....Changing the classification status quo with a global genome-based taxonomy. A grand challenge in biology is the reconstruction of the complete evolutionary history of life on our planet. A major hurdle to this goal has been the inability to culture most microbial species which comprise the bulk of evolutionary diversity. However, new molecular techniques have removed this hurdle and >1,000 new microbial species are being revealed each month through sequencing of environmental samples. This project aims to organise both cultured and uncultured microbial diversity into a systematic evolutionary framework to replace the current highly flawed and incomplete classification of microorganisms. The systematic classification of the microbial world is timely and will enable fundamental insights into ecology and evolution.Read moreRead less

This project aims to apply recently developed culturing methods to archive and phenotype bacterial species found in the human gut in a representative sample from metropolitan, rural and indigenous Australians. This project expects to isolate, genome sequence, classify, characterize and permanently archive 1500 bacterial species. Expected outcomes of this project include detailed knowledge of previously undiscovered bacterial species, improved methods to measure the bacterial species that inhabit the human gut and a detailed understanding of the gut microbiota of Australians. This project should significantly enhance our knowledge of bacterial diversity and evolution and provide detailed insights into bacterial transmission.Read moreRead less

Building virtual cyanobacteria: moving beyond the genomics era. This project aims to establish a new understanding of complex biological systems through the development of computational models of single cells and global ecosystems. The project will focus on globally important photosynthetic bacteria that underlie the entire marine food web. This project aims to characterise the diversity and abundance of photosynthetic bacteria across Australia's marine habitats and unravel the genetic basis for their adaptation to different environments. This data will be integrated with biochemical and physiological studies to create quantitative models at the cellular and global ecosystem scales. This project aims to develop new biomonitoring technologies, which combined with these models, will enable assessment of the health of Australia's marine ecosystems.Read moreRead less

One of the most difficult environmental issues for the mining industry is acid mine drainage (AMD) that can lead to significant environmental damage. This project aims to identify microbes and characterise their roles in AMD formation in north Australia. We will use our new knowledge to design and trial microbial mats for the treatment of AMD. A successful AMD microbial treatment technology will minimise the risk of acid runoff and metal seepage into rivers and through groundwater. AMD treatment technology we develop in the tropics where we experience the extremes of dry and wet seasons will require only minor modification to operate in temperate climates however the reverse is not true.

This project intends to characterise the genetic basis for colonisation and persistence on plant seeds and roots by biocontrol bacteria. Pseudomonas biocontrol bacteria offer the potential to suppress agricultural crop pathogens without the need for expensive and potentially harmful agrochemicals. However, the application of these bacteria in the field is currently limited. A key reason for this is their unreliable capacity for root colonisation and persistence. The project aims to analyse the factors critical for plant colonisation. These analyses may facilitate the successful application of biocontrol bacteria for protecting Australian crops from pathogens.Read moreRead less
