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
Molecular Cell Biology and Comparative Genomics Of Planctomycetes and Verrucomicrobia In Relation To Evolution Of Cytoskeletal Proteins and Membrane-bounded Compartments. Planctomycetes and verrucomicrobia are evolutionarily distinct groups of bacteria which possess unusual cell structure and which share some significant genes important in cell biology with eukaryotes e.g. in verrucomicrobia the cytoskeleton protein tubulin. These bacteria are important for understanding the transition from no ....Molecular Cell Biology and Comparative Genomics Of Planctomycetes and Verrucomicrobia In Relation To Evolution Of Cytoskeletal Proteins and Membrane-bounded Compartments. Planctomycetes and verrucomicrobia are evolutionarily distinct groups of bacteria which possess unusual cell structure and which share some significant genes important in cell biology with eukaryotes e.g. in verrucomicrobia the cytoskeleton protein tubulin. These bacteria are important for understanding the transition from non-nucleated cells with simple cell division to nucleated cells with chromosome separation via cytoskeletal protein movement.The project will compare genomes of of planctomycetes and verrucomicrobia to determine their relationship, determine whether the tubulin homolog of verrucomicrobia can form cytoskeleton structures, and characterize the cytoskeleton of ammonium-oxidizing planctomycetes used in wastewater treatment.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
Chromera velia - a new organism for understanding malaria and related parasitic diseases. Malaria and related parasitic diseases cause millions of deaths annually. Chromera velia is a recently discovered organism that was isolated from Australian corals and is the closest known relative to these parasites. Chromera is able to photosynthesis and live in the absence of a host, making it an excellent organism for developing antimalarial drugs.

Malaria and related parasitic diseases cause millions of deaths annually. Chromera velia is a recently discovered organism that was isolated from Australian corals and is the closest known relative to these parasites. Chromera is able to photosynthesis and live in the absence of a host, making it an excellent organism for developing antimalarial drugs. In this project we will determine key features of Chromera ecology, morphology, genetics and biochemistry. The resulting data will allow us to exploit Chromera as a model for developing anti-parasitic drugs and for understanding parasite evolution. Read moreRead less
Nuclear structure and function in the nucleated planctomycete bacterium Gemmata obscuriglobus: a third cell plan for living organisms? The project will contribute knowledge of how cells such as those of animals and plants evolved from bacterial components.

The project will contribute knowledge of how cells such as those of animals and plants evolved from bacterial components. Origins of cell nuclei and pores in nuclear membranes will be studied via the simple eukaryote-like nucleus of the planctomycete Gemmata obscuriglobus, from Australian freshwater. Simple nuclear pore-like structures of G. obscuriglobus will help understanding nucleus function in animal cells, and such pores will give insight into 'minimal' composition needed for cell nuclei, and allow design of biological nanopores. The origin of the nucleus is a major problem in biology, and an Australian contribution to its solution will achieve international recognition. Read moreRead less

The outcome of this research will be a better understanding of the genes involved with adaptation to particular pathogenic lifestyles. Specifically, genes that are rapidly evolving in selected bacterial pathogens of medical and veterinary importance will be identified using a bioinformatics approach that exploits the existence of multiple closely-related genome sequences. Such genes encode potential new targets for therapeutic intervention that provide alternatives in the face of emerging antibiotic resistance. Importantly, the methodology developed in this project is broadly applicable to the study of evolution of bacterial pathogenesis in any background: medical, agricultural or horticultural.Read moreRead less
