Extraction and formulation of astaxanthin produced in Phaffia rhodozyma fermentations
Traditionally derived from unsustainable petrochemicals, astaxanthin (AX) can also be sustainably produced by microbial fermentation. The yeast Phaffia rhodozyma naturally produces AX as its main fermentation product through sugar assimilation.In previous studies, we improved the bioprocess to produce (upstream) AX in P. rhodozyma. This project aims to investigate the extraction, recovery, and formulation (downstream) of the AX produced in our improved AX production process.AX is a carotenoid pigment and potent antioxidant naturally occurring in some ocean animals such as salmonids …

Application of fluorescence-activated cell sorting and confocal microscopy for the study of the microbial communities responsible for nutrient removal from domestic wastewater
The removal of nutrients like carbon, nitrogen and phosphorus from wastewater is critical to the prevention of eutrophication in receiving water systems and is carried out by complex microbial communities.Eutrophication can have devastating consequences on aquatic life and natural ecosystems, with toxic algal blooms also posing a risk to human health.Understanding the microbiology of phosphorus (P) removal from wastewater is considered essential to knowledge-based optimisation of enhanced biological P removal (EBPR) systems.Most of the species in these systems are novel …

Using machine learning to understand how the world’s microbiomes are changing due to climate
Shotgun metagenomic sequencing has become commonplace when studying microbial communities and their relationship with the health of our planet, and their direct effects on our own health. Currently, there are >180,000 shotgun metagenomes publicly available, but until recently trying to treat these data as a resource has been challenging due to its extreme size (>700 trillion base pairs).Recently we have developed a tool that can efficiently convert this base pair information into a straightforward assessment of which microorganisms are present …

Probing the origins of life on Earth
The history of life on Earth is written in the fossil record. In this project, you will investigate stable isotope evidence for extremely early evolving organisms. Through careful petrography and with the use of isotope ratio mass-spectrometers, you will help unravel the history of microbial metabolisms that powered the ecosystems recorded by 3 billion-year-old microbial fossils.

From a descriptive to a predictive understanding of the human microbiome
Microorganisms have a profound influence on biological, environmental, and industrial processes, but understanding the complex dynamics of microbial communities and how to manipulate them to our advantage remains a challenge. CMR Director Professor Gene Tyson has recently been awarded a prestigious ARC Laureate Fellowship that aims to overcome current technological limitations and transform microbial ecology from a descriptive to a predictive science. This will be achieved using as a model the most intensively studied ecosystem on the planet: the human …

BIOM05 - Application of fluorescence microscopy for the visualization of methane-oxidizing microorganisms in the environment
The archaeal lineage Methanoperedenaceae are anaerobic methanotrophs with a key role in mitigating the atmospheric release of the potent greenhouse gas methane. The metabolic diversity of these microorganisms directly links methane with several key biochemical cycles and suggests a remarkable ability of these microorganisms to adapt to diverse environmental conditions.These microorganisms have never been grown in a laboratory and have only been studied in enrichment cultures with several other partner microorganisms. How these microorganisms grow and interact with these bacterial …

Using time-controlled grazing to sequester carbon in Queensland rangelands
Time-controlled grazing (TCG), or cell grazing is a management strategy in which cattle are stocked and rotated across small paddocks or “cells” according to fodder availability. Grazing takes place in short durations at high stocking densities, in an effort to mimic the grazing patterns of wild ungulate herds.This management strategy has gained traction in recent years due to claims that it improves both pasture productivity and diversity, whilst also increasing long-term carbon pools. Limited data is available on the impact …

Comprehensive strain-level characterisation of microbial communities associated with inflammatory bowel disease
Inflammatory bowel disease (IBD) is a chronic, relapsing inflammatory disorder driven by complex interactions between environmental, microbial and immune-mediated factors 1,2. An unfavourable shift in gut microbiome composition, known as dysbiosis, is now considered a key feature of IBD 2-5, however it is unclear how specific microorganisms and their interactions with host cells contribute to disease onset and progression.Previous IBD studies have been largely limited to older sequencing methods with low phylogenetic and functional resolution. Furthermore, these studies have predominantly …

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 …
