The Environmental Microbiology Research Initiative (EMRI) is a research consortium that aims to explore how environmental microorganisms influence ecosystem and human health, change the chemistry of the planet, respond to the impacts of industrial contamination and climate change, and potentially yield new biotechnologies.
Environmental systems harbour complex microbial networks and interactions that reflect biological (including microbes and animal/plant hosts) and geological co-evolution, including the impacts of the Anthropocene. Only recently have the vastness, novelty and ingenuity of Earth’s microbiomes been revealed through technological advances and utilisation of multi-omics and visualistion approaches. Understanding the distribution, complexity and functionality of the planet’s largely non-pure-cultivated environmental microbes presents a new frontier of science.
EMRI is an interdisciplinary research initiative created to explore and make discoveries across this new frontier. EMRI involves five faculties at the University of Melbourne: Science; Engineering; Medicine, Dentistry and Health Sciences; Veterinary and Agricultural Sciences; and Arts.
- Research Program Overview
EMRI RESEARCH PROGRAM
EMRI research is grouped into three interconnected themes of microbial resilience, microbial systems and microbial evolution. The three themes underpin the research program that will address five key research objectives:
- Contribute strategically to the growing global catalogue of environmental genomes and metagenomics datasets
- Understand key environmental factors that shape microbial communities
- Predict adaptations in microbial communities and their functionality under changing environmental conditions
- Identify novel metabolic/enzymatic pathways for nutrient cycling or contaminant remediation
- Use metagenomics to drive cultivation-based hypothesis-testing experiments and selective enrichment/species isolations.

- Bioinformatics and Statistics Committee
The Bioinformatics and Statistics Committee ensures that EMRI researchers are kept abreast of information, skills, hardware/software and training courses in this field at the University of Melbourne. The committee will be aware of EMRI needs via surveys and other communications methods. It is anticipated that EMRI will facilitate specific courses and the committee will lead or oversee and ensure broadcasting of them.
Dr Heroen Verbruggen (Faculty of Science, School of BioSciences) (Chair)
- Heroen's interests span the fields of algal evolution, microbial symbiosis, genome evolution and bioinformatics. Heroen's research into the evolutionary diversification of marine algae, uses molecular phylogenetics to explore their diversification and answer specific questions about their evolution. Bioinformatics and phylogenetics take a central position in his approach to research questions.
Dr Dieter Bulach (Melbourne Bioinformatics and Faculty of Medicine, Dentistry and Health Sciences) (Deputy Chair)
- Dieter is an experienced bioinformatician specialising in microbial genomics. He is the European Molecular Biology Laboratory-Australian Bioinformatics Resource (EMBL-ABR) Activity Lead for Prokaryotes Bioinformatics. He works on a range of public health projects at the Peter Doherty Institute. Dieter specialises in both microbiology and bioinformatics, working on several major projects dealing with viruses and bacteria, especially pathogens.
Dr Kim-Anh Lê Cao (Melbourne Integrative Genomics and Faculty of Science, School of Mathematics and Statistics)
- Kim-Anh's main research focus is on variable selection for biological data (`omics' data) coming from different functional levels by the means of multivariate dimension reduction approaches. Since 2009, her team has been working on developing the statistical R toolkit mixOmics that is dedicated to the integrative analysis of `omics' data, to help researchers make sense of biological big data.
Dr Patrick Buerger (CSIRO and Faculty of Science, School of BioSciences)
- Patrick is a postdoctoral researcher with CSIRO's Synthetic Biology Future Science Platform and the University of Melbourne. His research focuses on climate change and anthropogenic impacts on coral reef ecosystems and he uses genetic engineering and a range of Omics technologies to investigate the thermal resilience of algal symbionts in corals.
Ms Evelyn Chou (Faculty of Science, School of BioSciences)
- Evelyn is a graduate researcher who explores density-dependent cell-cell chemical communication (quorum sensing) in the malaria parasite Plasmodium falciparum. Her work has shown that P. falciparum undergoes density-dependent cell death characterized by changes in parasite gene expression that are associated with sexual stage transmission, programmed cell death and clonal variation (a key regulator of infection and host interaction). Evelyn combines cellular and molecular biology, biochemistry, metabolomics, functional genomics, and bioinformatics to identify and understand the mechanisms underlying these responses.
- Social Science and Ethics Committee
Practical applications of discovery in environmental microbiology involve engaging with society. For example, water generated from bioremediation of polluted water could be used for irrigation and food grown on such irrigated land might be deemed negatively by some cohorts in society. Thus, attention to society's thoughts and opinions and to their embracing environmental microbiology applications must be considered early in several research projects. Our research and how our discoveries can benefit humanity and the environment must be communicated to the public early in the work timetable and in an effective manner.
Prof Yoshihisa Kashima (Faculty of Medicine, Dentistry and Health Sciences; email@example.com) (Chair)
- Yoshi's current research goal is to develop a social psychological theory of cultural dynamics, that is, how concrete individuals’ context specific activities in interaction with each other can generate and transform what we call culture. More specific projects include cultural comparisons in self and identity, narrative social influence in cultural transmission and transformation, cultural dynamics of nationalism, patriotism, and stereotyping, and connectionist modelling of cultural processes.
Dr Brock Bastian (Faculty of Medicine, Dentistry and Health Sciences; firstname.lastname@example.org)
- In his search for a new perspective on what makes for the good life, Brock has studied why promoting happiness may have paradoxical effects; why we need negative and painful experiences in life to build meaning, purpose, resilience, and ultimately greater fulfilment in life; and why behavioural ethics is necessary for understanding how we reason about personal and social issues and resolve conflicts of interest.
Prof Madeleine van Oppen (Faculty of Science; email@example.com)
- Her research focuses on microbial symbiosis in corals, adaptation/acclimatisation to climate change, and connectivity of coral reefs. Her work is increasingly focusing on ‘assisted evolution’, where mechanisms of adaptation and acclimatisation in corals and genetic manipulations to enhance stress tolerance and fitness of corals in a changing environment are explored.
Dr Kate Howell (Faculty of Veterinary and Agricultural Sciences; firstname.lastname@example.org)
- Kate studies food biochemistry and microbial ecology, by investigating yeast and bacterial communities in food ecosystems. Of interest are biochemical pathways of yeasts that influence flavour production during fermentations in a range of different foods and beverages.

EMRI Affiliated Postgrads
Ms Evelyn Chou (2014-2018) (email@example.com)
- Supervisors: Prof Karen Day, Dr Michael Duffy
- Project Title: Characterization and mechanisms of a novel density-dependent death phenotype in Plasmodium falciparum
- Brief Description: I explore quorum sensing in the malaria parasite Plasmodium falciparum, a form of cell-cell communication in which unicellular organisms count themselves through the secretion and reception of signaling molecules. Responses to quorum sensing can include the production of inhibitory factors that prevent or reduce growth and proliferation. P. falciparum parasites are temporally exposed to conditions of high parasite density during sequestration in the microvasculature, providing the ideal environment for density-dependent differential behavior. I show that P. falciparum undergoes density-dependent cell death characterized by changes in parasite gene expression that are associated with sexual stage transmission, programmed cell death and clonal variation (a key regulator of infection and host interaction). I also combine cellular and molecular biology, biochemistry, metabolomics, functional genomics, and bioinformatics to identify and understand the mechanisms underlying these responses.

- Supervisors: Dr John Moreau, Prof Jillian Banfield (Univ Melbourne, Univ California, Berkeley, USA)
- Project Title: Geomicrobiology of rare earth elements
- Description: The project aims to discover novel microbial compounds that liberate rare earth elements and phosphorus from minerals. By focusing on the interactions between soil microorganisms and lanthanide-phosphate minerals, this proposal seeks to understand how microbes break down these highly insoluble secondary minerals in the environment. Expected outcomes include new strategies for accessing phosphorus in depleted agricultural soils and recovering lanthanides from currently uneconomical mine tailings. This project will provide new knowledge of the microbially-controlled processes mediating the biogeochemical cycling of phosphorus and lanthanides in nature, for harnessing to improved land management and economical resource extraction.

Many EMRI research projects are cross-disciplinary but are grouped into the general topics below:
- Geomicrobiology and biogeochemistry of mercury methylation
Geomicrobiology and biogeochemistry of mercury methylation
The Moreau Geomicrobiology Lab studies the processes by which certain microorganisms convert toxic ionic mercury (Hg2+) into the more toxic organometallic compound, methylmercury (CH3Hg+).
This process occurs in aqueous environments from riverine sediments to the open ocean, but the mechanisms and triggers for microbial mercury methylation are still poorly understood.
- Bioremediation of mine wastes
Bioremediation of mine wastes
Some environmental microorganisms can biodegrade these contaminants into less harmful or non-toxic substances.
The Moreau Geomicrobiology Lab applies both cultivation-based and molecular biology approaches to developing new biotechnologies for mitigating mining impacts on soil and groundwater
Plant and Soil Microbiology
- Understanding the transmission of antibiotic resistance in agro-ecosystems
Funded by the ARC – DP170103628, $399,800
The emerging spread of antibiotic resistance genes (ARGs) represents a serious threat to human health. However, we have very limited knowledge about the pathways and mechanisms for transmission of ARGs in the environment. This project will use advanced molecular approaches to investigate all the major classes of ARGs in typical vegetable farms and animal manure, and to explore the major routes for transmission of ARGs from manure to soil and from rhizosphere to the vegetable surfaces and endophytic bacterial communities. The results will be integrated to identify the priority ARGs indicators with high likelihood of spread into food chain, and contribute to the development of management options to tackle environmental antibiotic resistance.
- Soil microbial indicators for efficient use of nitrification inhibitors
Funded by the ARC – LP160101134, $237,000
Nitrification inhibitors are one tool widely used to improve nitrogen fertiliser efficiency and reduce greenhouse gas nitrous oxide emissions. However their effectiveness is variable across soil types and one possible reason is the different microbial communities that exist in these soils. The project addresses the key knowledge gaps of interactions between the nitrification inhibitors and the soil functional microbial communities. The project aims to fundamentally improve our understanding of the efficiency and governing factors of the nitrification inhibitors in different agricultural soils, and thus provide guidance to develop sound management strategies to improve fertiliser nitrogen use efficiency in Australian Agricultural soils.
- Reserving nitrogen in soils through microbial nitrate reduction to ammonium
Funded by the ARC – DP160101028, $248,000
This project aims to identify those microbes able to transform nitrate to ammonium and thus increase soil nitrogen conservation. More than 50 per cent of the nitrogen in fertilisers applied to soils is lost into the environment, which is both a financial loss to farmers and a main anthropogenic source of nitrogen pollution. Some microbes can transform nitrate into ammonium through dissimilatory reduction (DNRA) and thus increase soil nitrogen retention. However, the DNRA process and the responsible microbial groups remain largely unknown. This project plans to use isotope tracing and biomolecular approaches to identify those DNRA microbial groups and elucidate the DNRA reaction process. The findings may support the use of DNRA to improve soil nitrogen.
- Fungal Biodiversity
The fungal kingdom are likely the most species rich group of microbes on earth, yet we have described less than 3% of all estimated species, and have only a limited understanding of how fungi contribute to the many environments in which they are found. From the species that have been studied, it is clear that fungi are critical for nutrient cycling and in interaction with plants and other microbes.
We are interested in fungal diversity from two perspectives. First is the impact of fungi and other microbes on disease in agricultural settings, in our case how other microbes impact the major diseases that impact the Australian canola (Brassica napus) industry. Second, is with colleagues at the Royal Botanic Gardens Victoria we are investigating the diversity and distribution of some of the poorly understood fungal taxa.
- Manipulation of microbes to assist coral adaptation to climate change

Our group is called the Marine Microbial Symbiosis group. We explore how corals interact with their associated microbial communities, and attempt to augment the capacity of corals to tolerate stress by manipulating these communities. Our research aims to support development of novel coral reef restoration approaches.
We use the sea anemone Exaiptasia pallida as a model animal, and focus on the role of prokaryotes and the algal symbiont Symbiodinium. The approaches used to manipulate microbial communities include use of probiotics, experimental evolution and genetic engineering.

- Fluid dynamics of corals
Fundamental processes underpinning the health and function of corals such as nutrient uptake, oxygen exchange and bacterial infection occur at the microscale, yet we still largely lack a quantitative understanding of the governing transport processes. The cilia that corals use for feeding and cleansing also generate dramatic vortical flows, which affect mass transport and may provide a barrier against infection. My research investigates the nature and consequences of these active vortical flows. I use state of the art visualisation of flows, tracking of individual bacterial cells, and mathematical modelling to quantitatively understand the coupling between ciliary flows, nutrient and oxygen dynamics, and pathogen behaviour.
- Micro-niches in the coral skeleton
Coral reefs are spectacular ecosystems held together by calcium carbonate structures secreted by corals (their skeletons). The diversity, spatial structure and functions of the microbiota residing in the skeleton underneath the coral tissue are barely understood.
We study the coral skeleton microbiome, focusing on the interactions between microbiota and the steep environmental gradients in oxygen, light and other nutrients present in the skeleton. We use planar optode imaging to visualise gradients in physicochemical properties and characterise of the microbial communities at different positions along the environmental gradients using molecular techniques.
- Endosymbiosis in the algal world
Microbial endosymbiosis, i.e. symbiosis where one cell lives inside another cell, is very commonly found in nature. These partnerships range from transient, fairly loose associations to well-established symbioses where neither of the partners can live without the other.
We are interested in many aspects of microbial symbiosis in marine algae. We characterise the nature and evolution of bacterial endosymbionts living within seaweeds and the origins of algal chloroplasts through endosymbiosis. We use a combination of microscopy, metabarcoding and whole-genome sequencing to characterise the partners, how they interact, and how their associations have evolved through geological time.
- Microbiologically influenced corrosion
Microbiologically influenced corrosion
Accelerated low water corrosion (ALWC) is a type of microbiologically influenced corrosion that substantially increases damage to metal structures in seawater around the low tide level. ALWC is a costly global issue.
We hypothesise that the functional features of microbes, including their propensity to attach to metal surfaces and their metabolic pathways, facilitate ALWC. We aim to identify the microbes in ALWC tubercles with the aim of better understanding this phenomenon.

- Microbial diversity and interactions in food ecosystems: from model to meal
Why does food taste better when a community of microbes is present? What can interactions between microorganisms tell us about wider ecological systems? The Howell lab studies yeast and bacterial communities in a wide variety of food ecosystems, including bread, beer, wine and chocolate. Analytical methods help us to understand the biochemical pathways of yeasts and bacteria that influence flavour production and draws these together with broader ecological and social understandings of taste, health and sustainability.

Computational Statistics and Microbiology
- Development and application of multivariate methods for microbiome studies
There are major statistical and computational challenges in analysing microbial communities that currently hinder the potential of microbiome research to substantially advance biomedical understanding. We are currently expanding mixMC to better characterise and understand important microbiome-host interactions. Some of our methods developments aim at addressing batch effects in microbiome experiments and analyse scarce temporal sampling in time course studies.
We analyse microbiome datasets from our collaborators for a wide range of studies, including investigating the role of gut and oral microbiome in spondyloarthropathy diseases, the development of intestinal or salivary microbiota in toddlers and infants, investigating the gut-brain crosstalk in Huntington’s disease.

- Development of the mixOmics R toolkit package
mixOmics is one of the few R package dedicated to the integration of multiple ‘omics data (19 novel methodologies implemented so far, amongst which 13 were developed by our lab) and with an increasing uptake from the research community. The package has been downloaded > 29K times in 2017, (R CRAN package download logs). Programming developments are on-going for interactive web interfaces, and efficient programming for large-scale studies. Check our our recent publication (Rohart et al. 2017b) and a poster that gives an overview of this large project. The mixOmics team run multiple day workshops for an introduction to multivariate projection-based methods for data integration using mixOmics, see our website www.mixOmics.org for news and tutorials.
- Microbial fluid dynamics
Microbial fluid dynamics
Fluid mechanics at the microscale governs a myriad of physical, chemical and biological processes in the environment.
We apply advanced video-microscopy and microfluidic techniques to directly visualise dynamic processes at the single cell level, from the collective beating of cilia to the active search behaviour of motile bacteria.
These results will uniquely inform the development of mathematical models with far-reaching ecological insights.
