Can cyanobacteria use organic nutrients to thrive in future oceans? Marine cyanobacteria are central to regulating the global climate and underpin entire marine food webs. Though they possess genes necessary to uptake diverse organic nutrients, we know very little about whether and how organic nutrients shape the physiology and ecology of cyanobacteria. Using our innovative high-throughput approach, this project aims to systematically characterise organic nutrient uptake in picocyanobacteria.

Though they possess genes necessary to uptake diverse organic nutrients, we know very little about whether and how organic nutrients shape the physiology and ecology of cyanobacteria. Using our innovative high-throughput approach, this project aims to systematically characterise organic nutrient uptake in picocyanobacteria. Our molecules-to-ecosystems approach expects to transform our understanding of alternate nutrient acquisition in cyanobacteria and how it may shape populations of these important photosynthetic organisms in a rapidly-changing ocean landscape.

This project aims to unveil the microbial diversity and metabolic capabilities of bark-dwelling microbial communities in Australian forests. Trees perform an important climatic function in sequestering atmospheric carbon, however the role of tree bark-associated microbiome in regulating other climate-active trace gasses such as methane, hydrogen and carbon monoxide is unknown. Combining cutting-edge molecular and biogeochemical approaches, this project aims to characterise and quantify trace gas oxidation rates of forest bark microbiome. The anticipated outcomes include fundamental knowledge surrounding bark-associated microbial trace gas oxidation within global biogeochemical cycles, and insights into their response to climatic variables.Read moreRead less

Environmental microbial communities are among the most abundant and diverse natural communities, responsible for many ecologically and economically important ecosystem functions, including primary productivity and climate regulation. This project aims to identify the biotic and abiotic factors that regulate community and functional outcomes of microbiome coalescence (the mixing of two different communities) caused by natural and anthropogenic activities. The outcomes will provide a unifying ecological framework to predict variation in microbiomes across different scales, ecosystem types and disturbances, and will generate critical knowledge for the development of effective microbiome products, a rapidly growing industryRead moreRead less
Defining how inter-bacterial symbioses regulate aquatic ecosystem health. This project will determine how ecological relationships among aquatic bacteria govern the health of Australia’s marine and freshwater environments. Cyanobacteria support aquatic ecosystem productivity, but can have detrimental effects when they form harmful blooms, although the factors governing the balance of these contrasting impacts are largely undefined. By coupling sophisticated approaches including genomics, phenomi ....Defining how inter-bacterial symbioses regulate aquatic ecosystem health. This project will determine how ecological relationships among aquatic bacteria govern the health of Australia’s marine and freshwater environments. Cyanobacteria support aquatic ecosystem productivity, but can have detrimental effects when they form harmful blooms, although the factors governing the balance of these contrasting impacts are largely undefined. By coupling sophisticated approaches including genomics, phenomics, and microfluidics to examine how symbioses with other bacteria influence the growth and function of important species of cyanobacteria, this research will elucidate the importance of an over-looked factor in controlling the productivity, health and value of Australia’s aquatic estate.Read moreRead less

A novel microbial process breaking through the nitrogen cycling. Nitrogen transformation is central to life on Earth. This project will challenge a century-old paradigm that microorganisms must cooperate in a team to convert nitrogen from organic- to inorganic forms. We will carry out the first-ever systematic investigation of a novel process, where a single organism mediates complete ammonification and ammonia oxidation, directly connecting organic- and inorganic nitrogen.

Key challenges for life are access to water & energy, and in cold, arid environments trace gas chemotrophy is used by soil microbiomes to sustain life. Given the cold, hyper-arid conditions on the Martian surface are analogues to ice-free regions of Antarctica, atmospheric chemoautotrophic ecosystems are the most promising ecological model for Martian life in the present or recent past. This project is significant, as it aims to define the limits to energy, water and carbon production via trace gas chemotrophy. We will integrate biology with astrophysics to identify at which point life ceases. Expected outcomes include new knowledge on the biological envelope, with benefits to include the identification of Martian regions for exploration.Read moreRead less
