The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

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
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. 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 mic ....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. 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

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
