Benefits accrue on two fronts: the international reputation of Australian science in contributing significantly to two new, challenging and highly topical questions in ecology and evolution, and in pioneering a route to better efficiency and control of an important industrial process. Wastewater is rich in organic phosphorus that is damaging to the environment if untreated, but current understanding enables only rudimentary control of the microbial communities that are the basis of the treatment process. The work will provide unprecedented insight into the mechanisms underpinning the dynamics of phosphorus absorbing microbes in industrial facilities by integrating from gene-to-ecosystem.Read moreRead less
Sulfur cycling in soil environments - how bacteria contribute to the oxidation of organic and inorganic sulfur compounds. Element cycling in soil environments is of global significance as soils constantly exchange compounds with the atmosphere and cover vast areas of land. Many of the compounds exchanged are known contributors to the greenhouse effect and other phenomena such as acid rain. By elucidating the regulation of bacterial sulfur oxidation pathways and their integration into general met ....Sulfur cycling in soil environments - how bacteria contribute to the oxidation of organic and inorganic sulfur compounds. Element cycling in soil environments is of global significance as soils constantly exchange compounds with the atmosphere and cover vast areas of land. Many of the compounds exchanged are known contributors to the greenhouse effect and other phenomena such as acid rain. By elucidating the regulation of bacterial sulfur oxidation pathways and their integration into general metabolism, we will enable the development of better management strategies for agricultural soils. Our data will also significantly improve understanding of how soil processes will change in response to changing climatic conditions.Read moreRead less

Exploring the evolution and ecology of non-photosynthetic Cyanobacteria. This project aims to contribute and expand our rudimentary understanding of non-photosynthetic Cyanobacteria by obtaining representative genome sequences using metagenomics. The dogma that all Cyanobacteria are photosynthetic has recently been challenged by the discovery of non-photosynthetic lineages. This project expects to obtain representative genome sequences using metagenomics to predict surface structures.

This project aims to contribute and expand our rudimentary understanding of non-photosynthetic Cyanobacteria by obtaining representative genome sequences using metagenomics. The dogma that all Cyanobacteria are photosynthetic has recently been challenged by the discovery of non-photosynthetic lineages. This project expects to obtain representative genome sequences using metagenomics to predict surface structures. The expected outcomes from this project includes providing insights into the function and evolution of non-photosynthetic Cyanobacteria and their viruses, and pure or enriched cultures to enable future studies.Read moreRead less
Understanding the mechanism of Wolbachia-mediated antiviral protection. Insects are involved in the transmission of many viral diseases of both plants and animals. A considerable number of these diseases have adverse effects for public health or cause large economic losses in agriculture. We were the first to discover that a common bacteria protects insects from virus infection. Knowledge of the mechanisms used by the bacteria to interfere with virus accumulation will facilitate novel strategies ....Understanding the mechanism of Wolbachia-mediated antiviral protection.

The findings of this project will enable Australian researchers and industry to design innovative approaches to control diseases that are transmitted by insects.Read moreRead less
Genome-level insight into the dynamics of a model coral microbiome. The aim of the project is to examine structural and functional microbiome dynamics in an ecologically important coral on the Great Barrier Reef along a natural temperature gradient. Microorganisms form an intimate symbiotic relationship with corals and are critical to their health. However, the microbiome can be disrupted by environmental perturbations, including higher-than-normal ocean temperatures, leaving the coral susceptib ....Genome-level insight into the dynamics of a model coral microbiome. The aim of the project is to examine structural and functional microbiome dynamics in an ecologically important coral on the Great Barrier Reef along a natural temperature gradient. Microorganisms form an intimate symbiotic relationship with corals and are critical to their health. However, the microbiome can be disrupted by environmental perturbations, including higher-than-normal ocean temperatures, leaving the coral susceptible to disease and bleaching. Currently, our understanding of how the microbiome composition and metabolic function change in response to seasonal temperature variation and disease is limited. This project is designed to provide insight into the role the microbiome plays in maintaining coral health and may aid in the long-term preservation of the reefs.Read moreRead less
