Microbial Genomics for Assessing the Health of Water Resources
Closing Date: 01 February 2021Apply Now
Disruption of the chemical and physical balance of aquatic microbial communities can result in the proliferation of harmful organisms, including toxic cyanobacteria (“blue-green algae”) and opportunistic pathogens. In all ecosystems, from the human gut to rivers, these tiny organisms are the "first responders" to environmental health and disease. Characterisation of the microbial and biochemical basis for water quality in resilient and impacted ecosystems will be invaluable for establishing future guidelines for water quality and safety. The innovative approach, predictive nature and translational capacity of this research project will enable water quality managers to develop contingency plans to reduce threats to freshwater supplies.
Three projects are available, and students can tailor their studies based on their interests and skills.
Project 1: We will apply a state-of-the-art, genetic and biochemical approach to identify the mechanisms of adaptation used by bloom-forming and toxic cyanobacteria. This project will, for the first time, assess their capacity for increased dominance, intensity and geographical distribution in Australian waterways. Understanding the molecular ecophysiology of these aquatic microorganisms is essential for improving risk assessment protocols and reducing the impact of harmful blooms.
Projects 2 and 3: Microbes in wastewater treatment plants impact on effluent quality and the utility of recycled water, posing a significant risk to the economy, the environment and public health. To understand the causes of cyanobacteria in pond-based (Project 2) and microbial filter-based (Project 3) wastewater treatment plants and the risk they pose, this research will use the latest molecular techniques to examine how the microbial communities within these systems interact with each other and their surrounding environment to form blooms and produce toxins and other harmful metabolites. Such knowledge will inform risk assessment and provide strategies for the mitigation of future bloom events, improving the security of our increasingly valuable recycled and treated water resources.
