THE BIOLOGY OF COLD ADAPTED EXTREMOPHILES: AN INTEGRATED GENOMIC-PROTEIN ANALYSIS APPROACH. Extremophiles are microorganisms that can thrive in otherwise inhospitable environments. Most extremophiles are Archaea; an order of life separate from Bacteria and Eucaryotes. The project will generate the first genome sequence that was initiated in Australia, and the first genome sequence of any cold adapted organism.

Extremophiles are microorganisms that can thrive in otherwise inhospitable environments. Most extremophiles are Archaea; an order of life separate from Bacteria and Eucaryotes. The project will generate the first genome sequence that was initiated in Australia, and the first genome sequence of any cold adapted organism. Associated functional studies include global analyses of protein expression (proteomics) and mRNA expression using micro-arrays, and work targeted at RNA binding proteins and protein folding systems involved in the thermally sensitive process of protein synthesis. The nature and scope of the work will impact on fundamental cellular processes and provide enormous innovative biotechnological potential.Read moreRead less

The mechanisms driving microbial navigation in marine systems. This project aims to apply advanced video-microscopy to characterise microbial motion at the single cell level, interrogating their navigational responses in precisely controlled physical and chemical conditions. Ocean carbon cycling is driven by the concerted action of marine microbes, but the fine-scale interactions between these microbes and their physical and chemical environments remains elusive.

This project aims to apply advanced video-microscopy to characterise microbial motion at the single cell level, interrogating their navigational responses in precisely controlled physical and chemical conditions. Ocean carbon cycling is driven by the concerted action of marine microbes, but the fine-scale interactions between these microbes and their physical and chemical environments remains elusive. The project findings will unravel the fundamental processes governing microbial motion in real environments, and develop the mechanistic modelling tools required to make quantitative ecosystem-level predictions of how soil-atmosphere-water-marine systems respond in the face of environmental change.Read moreRead less

Summary
The role of marine microbes in the global carbon cycle. This project aims to unravel microbiological processes in the ocean to help quantify the ecosystem services carried out by microbes that support our economy and environment. By recycling vital nutrients, microbes form the basis of the marine food web. In Australia, their contributions support fisheries worth $4.2 billion. Their role in carbon cycling also controls our climate. Yet, their direct productivity remains unquantified. Technical l ....The role of marine microbes in the global carbon cycle. This project aims to unravel microbiological processes in the ocean to help quantify the ecosystem services carried out by microbes that support our economy and environment. By recycling vital nutrients, microbes form the basis of the marine food web. In Australia, their contributions support fisheries worth $4.2 billion. Their role in carbon cycling also controls our climate. Yet, their direct productivity remains unquantified. Technical limitations have restricted our ability to identify the key microbes most responsible for ocean carbon cycling, and to measure their impact. This project plans to combine new approaches in microfluidics, chemistry and oceanography to quantify carbon uptake by individual microbes and provide new understanding of microbe-mediated chemical cycling processes.Read moreRead less

The proposed research will greatly contribute to our understanding of the functioning of a bacterial membrane channel/transporter, which has played a significant role in biotechnology of commercially important amino acids. A direct national benefit will result from establishing collaboration with a leading German laboratory providing expertise in protein biochemistry and molecular microbiology not available in Australia. The acquired knowledge will present an original contribution which will have a strong impact on a very competitive field of molecular microbiology and biotechnology.Read moreRead less
Coastal permeable sediments as a novel source of greenhouse gases. Emissions of the greenhouse gases nitrous oxide and methane are increasing from unknown sources. High concentrations of these gases have been observed in coastal waters which bear the brunt of nutrient pollution (primarily nitrogen) from cities and agriculture.

Superresolution fluorescence imaging in microbiology:
This project involves the purchase of new, and upgrade of existing, fluorescence imaging tools to facilitate the study of intracellular processes in microbial systems at significantly higher spatial and temporal resolutions than hitherto possible. Visualisation of the structure and dynamics of intracellular molecular assemblies at maximal resolution is required to understand protein function inside living cells. The new equipment is designed to provide a fast super-resolution imaging system to study the intracellular dynamics of proteins in vitro and a super-resolution microscope to visualise structures and assemblies inside microbes with a resolution of tens of nanometres, putting in vitro biochemistry into the context of a living cell.

This project aims to revolutionize our view of the microbial world once more by transforming microbiome studies from relative counts of organisms to actual numbers of microbes. This project expects to impact all the microbiome studies that are being performed worldwide by unveiling the actual numbers of microbes. Expected outcomes of this project include new techniques to enumerate the number of bacteria in different environments and new approaches to measure gene expression within individual bacteria in any environment that will be demonstrated with complex microbial communities. This should provide significant benefits because microbes affect every aspect of our lives and those effects are driven by how many microbes are present.Read moreRead less
