Genetic and environmental basis for endosperm hardness in malting barley. Barleys with a hard endosperm do not malt as well as other barleys, leading to under-modified malt. While malts may appear to be satisfactory by bulk chemical analysis, even relatively small amounts of under-modified malt causes problems in the brewing industry, such as slow filtration rates and increasing haze formation. We aim to examine two new procedures potentially useful in determining heterogeneity in barley hardn ....Genetic and environmental basis for endosperm hardness in malting barley. Barleys with a hard endosperm do not malt as well as other barleys, leading to under-modified malt. While malts may appear to be satisfactory by bulk chemical analysis, even relatively small amounts of under-modified malt causes problems in the brewing industry, such as slow filtration rates and increasing haze formation. We aim to examine two new procedures potentially useful in determining heterogeneity in barley hardness by examining single kernels, and investigating the role of barley variety and growing conditions on hardness.This project will aid in the production and selection of more uniform barleys for the malting and brewing industries.Read moreRead less
The microbiology and biotechnology of rum production. Rum is an alcoholic beverage produced by microbial fermentation of molasses waste from the sugar industry. The microbial species responsible for the process determine rum flavour and quality by production of specific aroma compounds. The rate and extent of fermentation determine process efficiency. Several yeast and bacterial species contribute to rum fermentation but this ecology is poorly defined. Through a combination of ecological stu ....The microbiology and biotechnology of rum production. Rum is an alcoholic beverage produced by microbial fermentation of molasses waste from the sugar industry. The microbial species responsible for the process determine rum flavour and quality by production of specific aroma compounds. The rate and extent of fermentation determine process efficiency. Several yeast and bacterial species contribute to rum fermentation but this ecology is poorly defined. Through a combination of ecological studies, controlled fermentations and distillation, chemical and sensory analyses, this project will determine the impact of particular microbial species on rum flavour and process efficiency. This information will be used by the industrial partner to enchance product quality and process efficiency.Read moreRead less

The successful execution of the project is expected to highlight that Australian malt and barley is of high quality so that the health of domestic customers is ensured and it attracts a premium from our export customers.Read moreRead less
Cosmopolitan development: the impacts of international volunteering. This project will provide new ways of thinking about the impact of international development volunteering. It examines how volunteering contributes to more equal partnerships between Australia and its neighbouring countries and how it transforms the ways volunteers and host organisations perceive and respond to global challenges.
Creating and sustaining a strong future for volunteering in Australia. This project seeks to answer the question of how to increase social participation by converting non-volunteers to the benefits of volunteering. In Australia today, communities and governments are increasingly dependent on volunteers to build social capital and deliver an increasing range of services. A world first, this project aims to create new theory by examining three levels of analysis: the micro level of the individual ....Creating and sustaining a strong future for volunteering in Australia. This project seeks to answer the question of how to increase social participation by converting non-volunteers to the benefits of volunteering. In Australia today, communities and governments are increasingly dependent on volunteers to build social capital and deliver an increasing range of services. A world first, this project aims to create new theory by examining three levels of analysis: the micro level of the individual volunteer or non-volunteer; the mezzo level of the volunteer-involving organisation; and the macro level of society. This innovative approach aims to identify, analyse and develop a tool to help organisations build Australia’s civil society and develop policy to create a sustainable volunteer sector into the future.Read moreRead less
Transitions of mobility and parking. Transitions of mobility and parking. This project aims to understand the role of parking in mobility, urban consolidation and transit-oriented development. Does parking supply affect travel demand, car ownership, and ultimately urban quality of life? New transitions and trends in land-use and transport, including car-sharing and automated vehicles, and the revival of urban living, raise important questions about the redesign and reuse of urban space. This pro ....Transitions of mobility and parking. Transitions of mobility and parking. This project aims to understand the role of parking in mobility, urban consolidation and transit-oriented development. Does parking supply affect travel demand, car ownership, and ultimately urban quality of life? New transitions and trends in land-use and transport, including car-sharing and automated vehicles, and the revival of urban living, raise important questions about the redesign and reuse of urban space. This project aims to give policy-makers an evidence base and toolkit to determine how best to repurpose the space currently accommodating private cars. This project is expected to make cities more attractive, efficient and liveable, improving a disproportionately large number of Australian lives.Read moreRead less
Monitoring organic matter in drinking water systems using fluorescence spectroscopy: improved early warning, process optimisation and water quality. Climate change is contributing to elevated organic matter (OM) concentrations in drinking water supplies. If insufficiently treated, OM can lead to unacceptable concentrations of disinfection by-products, considered to be potential carcinogens, as well as taste and odour problems and bacterial re-growth in the distribution system. Currently availabl ....Monitoring organic matter in drinking water systems using fluorescence spectroscopy: improved early warning, process optimisation and water quality. Climate change is contributing to elevated organic matter (OM) concentrations in drinking water supplies. If insufficiently treated, OM can lead to unacceptable concentrations of disinfection by-products, considered to be potential carcinogens, as well as taste and odour problems and bacterial re-growth in the distribution system. Currently available on-line monitoring techniques give limited information regarding the nature of OM; however, fluorescence spectroscopy has shown promise in this regard. Hence, this project aims to provide an on-line monitoring protocol utilising fluorescence to aid utilities in their provision of safe drinking water, thus addressing the National Research Priority goal water – a critical resource.Read moreRead less
