This project aims to characterise the evolutionary adaptations of a group of microorganisms with a key role in mitigating the release of methane into the atmosphere. Innovative molecular and visualisation-based approaches will be applied to uncover their metabolic diversity and evolutionary history. An important outcome of this study will be the comprehensive understanding of the contribution and impact these microorganisms have on the global carbon cycle, which will importantly inform accurate climate change models. This has clear benefits for society, given the precision of such models is essential in our ability to minimise the impact and associated cost of global warming.Read moreRead less
Uncovering new microbial players and processes in the global methane cycle. This project aims to utilise multiple analytical strategies (including metagenomics and metatranscriptomics) to substantially expand our understanding of the key microorganisms, metabolic strategies, and interspecies relationships involved in the formation and consumption of methane.

This project aims to utilise multiple analytical strategies (including metagenomics and metatranscriptomics) to substantially expand our understanding of the key microorganisms, metabolic strategies, and interspecies relationships involved in the formation and consumption of methane. The global methane cycle is controlled by microorganisms that produce and consume this important greenhouse gas, however it is now recognised that there are many as-yet undiscovered methane-metabolising microorganisms in the environment. The project will lead to a greater understanding of the contribution of these novel microorganisms to global carbon cycling and their links to climate change. This will directly benefit modelling efforts to understand future climate change scenarios.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. The proposed research aims to combine single cell genomics and super resolution microscopy for novel, high-throughput, genome-b ....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. 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

Summary
Annotating unknown microbial gene functions with organic matter change. This project intends to develop a new method for determining the function of microbial genomes. Microbes are all pervasive on Earth. It is now possible to routinely sequence microbial genomes. However, the function of most genes encoded on these genomes remains elusive, severely limiting our understanding of most ecosystems.

This project intends to develop a new method for determining the function of microbial genomes. Microbes are all pervasive on Earth. It is now possible to routinely sequence microbial genomes. However, the function of most genes encoded on these genomes remains elusive, severely limiting our understanding of most ecosystems. This project seeks to develop new methods to assign function to uncharacterised genes, by correlating changes in metabolite abundance with gene expression in a model permafrost thaw peatland. Determining the function of uncharacterised genes has widespread implications for microbial ecology and its numerous real-world applications, from determining soil greenhouse gas emissions to understanding human intestinal flora.Read moreRead less

This project aims to discover methane-metabolising microorganisms and link their metabolic capabilities to cryptic parts of the carbon cycle. To date, only a small fraction of microbial diversity has been characterised, so there are significant gaps in our understanding of carbon cycling, while the metabolic capabilities of undiscovered and widely distributed microorganisms involved in methane metabolism remain unknown. This project will study these microorganisms’ metabolic pathways using DNA sequencing, bioinformatics and cultivation techniques. By understanding these microorganisms’ metabolisms, researchers expect to assess how they affect global carbon cycling and climate change.Read moreRead less
Evolution of the marsupial gut microbiome and adaptation to eucalypt toxins. Eucalyptus leaves comprise all or part of the diet of some marsupials including koalas. Gut microbiota assist in the ability of these folivores to tolerate eucalyptus toxins although present understanding of this process is rudimentary.

Eucalyptus leaves comprise all or part of the diet of some marsupials including koalas. Gut microbiota assist in the ability of these folivores to tolerate eucalyptus toxins although present understanding of this process is rudimentary. This project aims to use culture-independent molecular methods to identify and characterise gut populations involved in phytochemical detoxification by comparative analysis with diprotodont relatives that are not capable of digesting eucalyptus leaves. This will highlight evolutionary convergence of gut microbiomes in toxic folivores and reveal mechanisms by which microorganisms respond to and metabolise eucalypt toxins. A broader evolutionary context of marsupial digestive function will assist in ongoing conservation efforts.Read moreRead less
