Bacterial Proteomics: From Cell Division to Novel Antibiotic Targets. When a cell divides it is essential that each newborn cell gets a complete copy of the DNA. To ensure that this happens, cell division must be tightly controlled. It is not known how this occurs in bacteria. However, if we knew what molecules were involved in this control, we could target them to kill harmful bacteria. This project aims to identify such regulatory molecules as candidate targets for antimicrobial agents, with a ....Bacterial Proteomics: From Cell Division to Novel Antibiotic Targets. When a cell divides it is essential that each newborn cell gets a complete copy of the DNA. To ensure that this happens, cell division must be tightly controlled. It is not known how this occurs in bacteria. However, if we knew what molecules were involved in this control, we could target them to kill harmful bacteria. This project aims to identify such regulatory molecules as candidate targets for antimicrobial agents, with a view to developing powerful, novel antibiotics to protect us from the imminent threat of bioterrorism and antibiotic-resistant bacteria.

The melioidosis agent Burkholderia pseudomallei in the anthropogenic environment of northern Australia. This project will analyse environmental factors contributing to the persistence of the soil bacterium and melioidosis agent, Burkholderia pseudomallei in the anthropogenic environment. This will increase understanding of the consequences of land use manipulations upon these bacteria and will suggest remediation measures to reduce the risk of exposure.
The development and evaluation of a new therapy for the prevention and treatment of bacterial infections in hospitals. The technology used in this project will enable products to be developed from the Australian dairy industry which may safely provide protection and treatment for diarrhoea acquired in hospitals for which there are few effective options. The product will be cost effective and can be used as a public health tool to control outbreaks in those most susceptible to severe disease.
Skin friction control using engineering and biological surface coatings. The development of techniques to reduce skin friction in water conveying assets will increase renewable energy production from existing hydro-electric plant and improve the energy efficiency of water conveying utilities. There is also potential for application to marine biofouling problems and reducing fuel usage by shipping. Passive (non-chemical) and biological control methods to reduce fouling and friction will be sought ....Skin friction control using engineering and biological surface coatings. The development of techniques to reduce skin friction in water conveying assets will increase renewable energy production from existing hydro-electric plant and improve the energy efficiency of water conveying utilities. There is also potential for application to marine biofouling problems and reducing fuel usage by shipping. Passive (non-chemical) and biological control methods to reduce fouling and friction will be sought to minimise environmental impact and maintain potable water quality. This multidisciplinary project combining engineering, photogrammetry and biological sciences will provide valuable training for the project team members and develop a pool of skilled personnel available to Australian industries.Read moreRead less
Targeted isolation of specific marine bacterial species associated with higher organsims for the purpose of discovering new antimicrobial compounds. Specific bacterial species that are commonly found in association with marine plants and animals often produce active secondary metabolites. The aim of this project is to apply our understanding of these bacterial-host associations to the targeted isolation of novel antimicrobials from the marine environment. While these new compounds will undoubted ....Targeted isolation of specific marine bacterial species associated with higher organsims for the purpose of discovering new antimicrobial compounds. Specific bacterial species that are commonly found in association with marine plants and animals often produce active secondary metabolites. The aim of this project is to apply our understanding of these bacterial-host associations to the targeted isolation of novel antimicrobials from the marine environment. While these new compounds will undoubtedly have a number of commercial applications this project focuses on the development of products for dental hygiene in animals. Generally, the urgent need for new antimicrobial compounds to combat the growing number of microbes that are resistant to current antibiotics highlights the importance of this project.Read moreRead less
Investigating the Ability of Honey to Inhibit Bacterial Biofilms Found in Chronic Wounds. Chronic (non-healing) wounds are a serious health problem in Australia. One quarter of our institutionalized aged population have pressure ulcers. The difficulty in treating these wounds is that most contain communities of bacteria, called biofilms, that are not killed by conventional antibiotics. Special honeys from Australia and NZ that are effective in chronic wound treatment can eradicate these biofilms ....Investigating the Ability of Honey to Inhibit Bacterial Biofilms Found in Chronic Wounds. Chronic (non-healing) wounds are a serious health problem in Australia. One quarter of our institutionalized aged population have pressure ulcers. The difficulty in treating these wounds is that most contain communities of bacteria, called biofilms, that are not killed by conventional antibiotics. Special honeys from Australia and NZ that are effective in chronic wound treatment can eradicate these biofilms. This project will identify the components in honey that do this and determine how they do it, to provide a more effective chronic wound treatment. It will decrease the prevalence of these wounds in Australia and the associated personal trauma and health costs.Read moreRead less

One of the most difficult environmental issues for the mining industry is acid mine drainage (AMD) that can lead to significant environmental damage. This project aims to identify microbes and characterise their roles in AMD formation in north Australia. We will use our new knowledge to design and trial microbial mats for the treatment of AMD. A successful AMD microbial treatment technology will minimise the risk of acid runoff and metal seepage into rivers and through groundwater. AMD treatment technology we develop in the tropics where we experience the extremes of dry and wet seasons will require only minor modification to operate in temperate climates however the reverse is not true.

World-wide, there is much active research to maximise the use of Rhizobium for legumes and to develop a new range of growth-promoting micro-organisms for application to agricultural crops including cereals. However, very poor survival of inoculant bacteria after application to seed severely limits their effectiveness. New polymer coatings on seed may enhance survival of inoculants. By collaboration between chemists, rhizobiologists and the inoculant and seed-coating industries, innovative technology can now be generated, improving inoculum potential, giving higher crop yields using less fertilisers. The technology will generate a rural service industry providing coated seed products that reduce farmers' input costs and help maximise their income.Read moreRead less
