A novel process for removing phosphorus microbiologically from wastewater. Australia is a water limited continent, and its rivers and lakes are priceless assets, but because of climatic conditions, these are especially sensitive to blooms of 'blue green algae'. Some are highly toxic, and water containing them is unsuitable for most purposes. Current technology for P removal requires constructing complex plant configurations, and most of these operate unpredictably and unreliably. This project ....A novel process for removing phosphorus microbiologically from wastewater. Australia is a water limited continent, and its rivers and lakes are priceless assets, but because of climatic conditions, these are especially sensitive to blooms of 'blue green algae'. Some are highly toxic, and water containing them is unsuitable for most purposes. Current technology for P removal requires constructing complex plant configurations, and most of these operate unpredictably and unreliably. This project will develop and fully evaluate a revolutionarily different alternative with a fully aerobic system, capable of being added onto the end of a conventional treatment plant, making protection of rivers and streams simpler and more feasible.

Functional Analyses of Bacteria Involved in Enhanced Biological Phosphorus Removal from Wastewater. The abundant growth of blue-green algae in global waterways is substantially caused by phosphorus (P) release from wastewater treatment plants. This environmental drama can be mitigated against by P-accumulating bacteria partitioning the P inside their cells. The P-removal process often fails, but since the metabolism of P-accumulating bacteria is unknown, remedial actions are based on conjecture ....Functional Analyses of Bacteria Involved in Enhanced Biological Phosphorus Removal from Wastewater. The abundant growth of blue-green algae in global waterways is substantially caused by phosphorus (P) release from wastewater treatment plants. This environmental drama can be mitigated against by P-accumulating bacteria partitioning the P inside their cells. The P-removal process often fails, but since the metabolism of P-accumulating bacteria is unknown, remedial actions are based on conjecture. This fundamental, knowledge-generating project will address this shortfall and will develop methods to evaluate the activity of P-accumulating bacteria, contributing substantial understanding of their metabolism. The final goal is to promote stable, reproducible P-removal from wastewater.Read moreRead less
The only constant is change: ecology and evolution of phage-host interactions in a model ecosystem. Microorganisms underpin life on Earth, but our understanding of their diversity and activity is limited by our inability to grow most of them in the laboratory. Recently, new techniques have emerged that allow access to the genetic information of all microorganisms by directly sequencing DNA and RNA from the environment.

Microorganisms underpin life on Earth, but our understanding of their diversity and activity is limited by our inability to grow most of them in the laboratory. Recently, new techniques have emerged that allow access to the genetic information of all microorganisms by directly sequencing DNA and RNA from the environment. In this research we will further develop these frontier technologies, promoting this new area of science in Australia. We will apply these techniques to microbial communities involved in wastewater treatment in order to understand the interactions between microorganisms and the viruses that infect them. Understanding this interaction will have important implications for optimising these treatment processes.Read moreRead less
