The mobilome of the anaerobic methanotrophic archaea Methanoperedenaceae. Microorganisms play a critical role in regulating Earth’s climate, but how they are affected by our rapidly changing environment is not well understood.

Microorganisms play a critical role in regulating Earth’s climate, but how they are affected by our rapidly changing environment is not well understood. This Discovery project will study a group of microorganisms found in freshwater sediment that can consume the potent greenhouse gas methane before it is released into the atmosphere. We have developed new methods to investigate how genetic material is exchanged between microorganisms, and how this helps them adapt to environmental changes. Together, this will ultimately help us develop better climate change prediction models and contribute to our understanding of microbial communities that are crucial for environmental health.Read moreRead less
Unlocking the potential of bacterial polymers by defining key determinants. Sugary structures that coat the surface of some bacteria, known as capsules, can be modified by bacterial viruses (bacteriophage) in the environment. For the bacterial genus Acinetobacter, this influences their use as naturally renewable 'green' biopolymers for remediating environments contaminated with petroleum hydrocarbons. This project aims to characterise crucial capsule polymerase enzymes using a combination of bio ....Unlocking the potential of bacterial polymers by defining key determinants. Sugary structures that coat the surface of some bacteria, known as capsules, can be modified by bacterial viruses (bacteriophage) in the environment. For the bacterial genus Acinetobacter, this influences their use as naturally renewable 'green' biopolymers for remediating environments contaminated with petroleum hydrocarbons. This project aims to characterise crucial capsule polymerase enzymes using a combination of bioinformatics and experimental methodologies to establish how bacteriophage influence Acinetobacter capsules. Outcomes include the development of an innovative genomics pipeline to detect capsule change, improving the use of living bacteria for bioremediation and sustainable rehabilitation of natural ecosystems.Read moreRead less

From a descriptive to a predictive understanding of the human microbiome. Microorganisms inhabit every imaginable environment on Earth. Despite advances in characterising microbial communities, our understanding is largely descriptive and a detailed appreciation of their complexity eludes us.

Despite advances in characterising microbial communities, our understanding is largely descriptive and a detailed appreciation of their complexity eludes us. This Laureate project aims to transform microbial ecology into a predictive science, through intensive investigation of the human gut microbiome as a model ecosystem. Major challenges in microbiology are expected to be overcome, with new knowledge for predicting how microorganisms influence, and are influenced by, their environment. Ultimately this knowledge can help us manipulate microbial communities in diverse ecosystems to our advantage – protecting the planet’s natural assets, and improving agriculture and human health.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
Unravelling a novel stress-signalling system in bacteria. This project aims to investigate the cyclic-di-AMP signalling system in industrially important bacteria. The recently discovered cyclic-di-AMP is essential for normal bacterial growth and plays key roles in heat and antibiotic resistance, metabolism and virulence. This project will develop new biological assays to shed light on how bacteria sense and respond to environmental stress. Expected outcomes include a much deeper understanding of ....Unravelling a novel stress-signalling system in bacteria. This project aims to investigate the cyclic-di-AMP signalling system in industrially important bacteria. The recently discovered cyclic-di-AMP is essential for normal bacterial growth and plays key roles in heat and antibiotic resistance, metabolism and virulence. This project will develop new biological assays to shed light on how bacteria sense and respond to environmental stress. Expected outcomes include a much deeper understanding of signalling inputs and outputs. This should lead to benefits such as guiding the improvement of bacterial strains used in food and biochemical biotechnological applications, and may provide the foundation for the development of novel antibiotics.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
YhcB, a crucial player in the control of bacterial cell envelope biogenesis. All life depends on a cell envelope to enclose the chemical reactions that make life possible. But how do cell envelopes grow? How each component of the cell envelope is incorporated into the envelope at the right amount and in the right time to prevent cell death, has been a longstanding question in bacteriology. Using a unique combination of high through put genetic screens and biochemical approaches, this project wil ....YhcB, a crucial player in the control of bacterial cell envelope biogenesis. All life depends on a cell envelope to enclose the chemical reactions that make life possible. But how do cell envelopes grow? How each component of the cell envelope is incorporated into the envelope at the right amount and in the right time to prevent cell death, has been a longstanding question in bacteriology. Using a unique combination of high through put genetic screens and biochemical approaches, this project will characterise a key regulator of cell envelope growth in Gram-negative bacteria. Knowledge arising from this research will provide insight into a fundamental process in bacteria, will develop new technology to probe protein interactions, and will provide novel avenues to solve infection in plants, humans and animals.Read moreRead less
