Diversity of Salinispora actinobacteria producing pharmaceutically relevant natural products from Australian marine sponges. By investigating the distribution of marine microbial resources relevant to drug discovery, we will directly contribute to ARC's Research Priority I - An Environmentally Sustainable Australia Priority Goal and the Priority Goal 'Sustainable use of Australia's biodiversity'. We will determine sources of marine bacteria and their genes useful for discovery of new natural pro ....Diversity of Salinispora actinobacteria producing pharmaceutically relevant natural products from Australian marine sponges. By investigating the distribution of marine microbial resources relevant to drug discovery, we will directly contribute to ARC's Research Priority I - An Environmentally Sustainable Australia Priority Goal and the Priority Goal 'Sustainable use of Australia's biodiversity'. We will determine sources of marine bacteria and their genes useful for discovery of new natural products for treatment of human diseases. We will do this by understanding where new strains of Salinispora bacteria may be isolated and how they are distributed in association with Australian marine sponge fauna, and by determining the distribution and chemical and genetic diversity of novel marine Salinispora bacteria.Read moreRead less
Microbial Ecology and Control of Foaming in Anaerobic Digesters. One of the world's most common treatments of biosolids (product of wastewater treatment), anaerobic digestion often suffers from accumulation of biological foam. This foam hinders treatment, personnel health and safety, legal requirements for environmental protection are jeopardised and attempts to control digester foaming are costly. There is a clear lack of knowledge about the organisms involved and causes, therefore no informe ....Microbial Ecology and Control of Foaming in Anaerobic Digesters. One of the world's most common treatments of biosolids (product of wastewater treatment), anaerobic digestion often suffers from accumulation of biological foam. This foam hinders treatment, personnel health and safety, legal requirements for environmental protection are jeopardised and attempts to control digester foaming are costly. There is a clear lack of knowledge about the organisms involved and causes, therefore no informed solutions exist. Molecular DNA techniques, 16SrDNA sequencing and DGGE, will assist in deciphering causes and organisms involved. Research outcomes will present environmental, legal and economical acceptable control strategies for digester foaming to the waste management and water industries.Read moreRead less
Understanding the role of a newly recognised retrovirus in the induction of cancer and immunosuppressive disease in koalas. Leukaemia, lymphoma and opportunistic infections are major causes of mortality in both captive and wild koala populations. It is our hypothesis that a recently discovered retrovirus is responsible for these disease syndromes. Using a multidisciplinary approach, this project will determine viral parameters that correlate with the disease status of koalas and lead to improvem ....Understanding the role of a newly recognised retrovirus in the induction of cancer and immunosuppressive disease in koalas. Leukaemia, lymphoma and opportunistic infections are major causes of mortality in both captive and wild koala populations. It is our hypothesis that a recently discovered retrovirus is responsible for these disease syndromes. Using a multidisciplinary approach, this project will determine viral parameters that correlate with the disease status of koalas and lead to improvements in diagnosis and management of disease in koala populations. The planned research will also provide some insight into cross-species transmission of retroviruses.Read moreRead less
Environmental genomics and novel bioactives from microbial communities on living marine surfaces. This project has three linked benefits to Australia. One, it is the first study to use environmental genomics analysis in an Australian marine ecosystem, thus bringing into the Australian scientific community the cutting edge technology for studying diverse microbial communities. Two, by using this technology we will be able to investigate Australian marine biodiversity to an unprecedented extent. ....Environmental genomics and novel bioactives from microbial communities on living marine surfaces. This project has three linked benefits to Australia. One, it is the first study to use environmental genomics analysis in an Australian marine ecosystem, thus bringing into the Australian scientific community the cutting edge technology for studying diverse microbial communities. Two, by using this technology we will be able to investigate Australian marine biodiversity to an unprecedented extent. Three, this newly revealed diversity will then be mined for novel bioactives for use in pharmaceutical and other human health applications. Read moreRead less
Taxonomic discrimination and compositional analysis of microalgae using Fourier-transform infrared (FT-IR) spectroscopy. The project aims to develop an automated system using infrared spectroscopy that can rapidly and inexpensively identify algae and quantify their chemical composition. The system, which would be based on statistical models developed from infrared spectral information, has the potential to enable rapid identification of blue-green algae at the strain level, allowing new algal bl ....Taxonomic discrimination and compositional analysis of microalgae using Fourier-transform infrared (FT-IR) spectroscopy. The project aims to develop an automated system using infrared spectroscopy that can rapidly and inexpensively identify algae and quantify their chemical composition. The system, which would be based on statistical models developed from infrared spectral information, has the potential to enable rapid identification of blue-green algae at the strain level, allowing new algal blooms to be rapidly compared with those known to be toxic. Compositional analysis using infrared spectroscopy has the potential to measure all major classes of macromolecules simultaneously and precisely, at the single cell level, in a non-destructive manner that does not involve polluting chemicals.Read moreRead less
