Australia's freshwater ecosystems: how microbial diversity and functionality influence harmful cyanobacterial blooms. Toxic cyanobacterial blooms are a constant threat to safe drinking water supplies. A bloom is a poorly understood interaction between many species and the environment. This project will investigate the entire microbial population and their physiologies present in a bloom event in order to identify potential targets for their management.

A time of flight secondary ion mass spectrometer facility for elemental and isotopic imaging of ultra-fine features: Microbiology has long been an area of strength in Australian science. With recent technological advances microbiology has entered a new golden age unveiling an extraordinary level of diversity and the central role of microbes in global biogeochemistry. The 'omics' era is generating endless hypotheses regarding geochemical processes carried out by microbes and this necessitates the application of advanced technologies to generate empirical support. Time of flight secondary ion mass spectrometry has emerged as a key tool to unravel elemental cycling carried out by microorganisms in mixed species communities in contexts ranging from terrestrial to marine ecology and from groundwater bioremediation to biogas production biotechnologies.Read moreRead less

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.
Determinants of substrate preferences and environmental applications of the copper membrane monooxygenases. The project aims to improve sustainability of environmental problems related to methane emissions, nitrogen cycling and pollution. We are developing tools targeting microbial genes correlated to all these issues. Data from these tests provides the information needed for monitoring environmental health and development of sustainable solutions.
Functional complexity of modern marine stromatolites. This research has the potential for providing the most detailed data regarding these ancient ecosystems, and will provide information for the environmental management of the famous modern stromatolites of Western Australia. Australia needs scientists applying their research to interactions of microorganisms with earth materials, and the synergy between biology and geology undertaken here has the potential to solve many outstanding problems in ....Functional complexity of modern marine stromatolites.

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
The dynamics of evolution: How horizontal gene transfer drives the diversification and adaptation of complex, bacterial communities. The genetic exchange between populations is a prerequisite for the long-term evolution of bacteria, however its short-term dynamics are largely unexplored.

This project aims to define the temporal dynamics of gene transfer and how it shapes the genetic composition of entire bacterial communities. Using innovative DNA sequencing technologies and bioinformatics, This project aims to offer a significant new understanding of the short-term diversification of communities and how different evolutionary forces shape bacterial function. It will show how bacterial systems can adapt to new environmental conditions and the effect on essential ecosystem functions.Read moreRead less
Lifestyle choices: genomic analysis of niche adaptations in marine Synechococcus. Photosynthetic marine bacteria are very important in the global carbon cycle. This project aims to discover how these bacteria adapt to survive in different marine environments. This is important for understanding how they will be affected by climate change and other environmental alterations.

Summary
The role of deep-sea microorganisms in nutrient cycling in the Southern Ocean. This project aims to learn how surface water microbes that are important in global nutrient cycling adapt to life when they sink to the deep sea. This will teach us about the roles that surface water and deep sea microbes play in maintaining the health of marine environments.
New tools to decipher, predict and manage pacific oyster mortality episodes. This project aims to unite cutting-edge genomic and molecular biological tools with novel quantitative modelling analyses to identify the mechanisms behind oyster disease events. Oyster farming contributes almost $100 million to the Australian economy each year and is a cornerstone of coastal communities, but has been decimated by diseases that threaten this important primary industry.

This project aims to unite cutting-edge genomic and molecular biological tools with novel quantitative modelling analyses to identify the mechanisms behind oyster disease events. Oyster farming contributes almost $100 million to the Australian economy each year and is a cornerstone of coastal communities, but has been decimated by diseases that threaten this important primary industry. While some causative pathogens have been identified, the environmental catalysts of oyster disease remain a mystery. The expected outcome of this project is an innovative coupling of tools that provides new capacity to forecast disease events, delivering the Australian oyster industry a powerful platform to predict, manage and prevent costly disease outbreaks. By identifying environmental thresholds and oyster disease danger periods, an expected outcome of this project is the development of new oyster farming strategies aimed at avoiding multi-million dollar losses associated with disease outbreaks.Read moreRead less
