This project aims to understand the mechanisms that control cell wall stability in the fish pathogen, Saprolegnia parasitica. The biochemical properties and function of vital enzymes involved in cell wall biosynthesis will be determined using innovative approaches at the interface of biochemistry, microbiology, cell biology, and structural biology. Next generation ion mobility mass spectrometry will be used to solve challenging structural questions that cannot be tackled with conventional techniques. Expected outcomes include new knowledge on challenging membrane proteins that allows development of novel strategies for disease control in aquaculture. The data may also be applicable to crop protection from related plant pathogens.Read moreRead less

The research findings will be useful to a wide spectrum of manufacturing industries which are currently generating slightly contaminated wastewater, and will be beneficial to the community in general. At the same time, the industries will be a step forward toward sustainable manufacturing.Read moreRead less
Development of novel omega-3 enriched poultry products. New Health recommendations and changes to the Food Standards Code encourage greater dietary intake of omega-3 (w-3) fatty acids. Our core research on modifying fatty acid composition of poultry tissues and preliminary studies with our industry partner's proprietary fishmeal product (PorcOmega) have indicated the feasibility of producing novel meat products and eggs with high w-3 contents, which would qualify to carry a new nutrition label. ....Development of novel omega-3 enriched poultry products. New Health recommendations and changes to the Food Standards Code encourage greater dietary intake of omega-3 (w-3) fatty acids. Our core research on modifying fatty acid composition of poultry tissues and preliminary studies with our industry partner's proprietary fishmeal product (PorcOmega) have indicated the feasibility of producing novel meat products and eggs with high w-3 contents, which would qualify to carry a new nutrition label. We now propose, in collaboration with our industry partner, to assess the viability of producing such products by conducting poultry feeding trials with PorcOmega on a commercial scale and evaluating both the levels of w-3 enrichement of chicken breast, thigh and sausages, shelf-life and consumer acceptability (sensory evaluation) of these products. We expect to establish feeding strategies for adoption by commercial producers of premium poultry and eggs for local or export markets.Read moreRead less
Development and application of an index for substantiating health benefits of omega-3 enriched foods. A cost-effective means of substantiating health claims for omega-3 (w3) rich functional foods is needed to fully exploit growing consumer demand for these products. In a two-stage approach, cardiovascular and anti-inflammatory benefits of w3 will be assessed in human dietary trials; improvements of health status in response to graded doses of w3 supplements will be correlated with docosahexaenoi ....Development and application of an index for substantiating health benefits of omega-3 enriched foods. A cost-effective means of substantiating health claims for omega-3 (w3) rich functional foods is needed to fully exploit growing consumer demand for these products. In a two-stage approach, cardiovascular and anti-inflammatory benefits of w3 will be assessed in human dietary trials; improvements of health status in response to graded doses of w3 supplements will be correlated with docosahexaenoic acid (DHA) levels in erythrocytes (DHA Index). Simple bioavailability trials can then be used to determine the intakes of foods required to attain the DHA Index, thus confirming their potential to deliver specified health benefits. Initial trials will support health claims for w3 rich fresh pork and processed pork products.Read moreRead less
Native fish stocking of rivers: discriminating between hatchery-reared and wild fish. Stocking of fish is widely used in attempts to restore native fish populations. Little is known of the fate of stocked fish or the effects of stocking on resident populations. We will develop and evaluate protocols for chemical marking of otoliths of hatchery-reared fish so that their source can be determined. Experimental stocking of hatchery-reared fish will be undertaken and population structure and sourc ....Native fish stocking of rivers: discriminating between hatchery-reared and wild fish. Stocking of fish is widely used in attempts to restore native fish populations. Little is known of the fate of stocked fish or the effects of stocking on resident populations. We will develop and evaluate protocols for chemical marking of otoliths of hatchery-reared fish so that their source can be determined. Experimental stocking of hatchery-reared fish will be undertaken and population structure and source of stocked versus wild fish determined in stocked and unstocked rivers. Natural chemical signatures will also help determine important recruitment areas. The outcomes will allow fisheries managers to make informed decisions regarding stocking strategies.Read moreRead less
Trojan Y as a genetic solution for controlling and eradicating the Eastern mosquitofish, Gambusia holbrooki. The project aims to develop applied genetic strategies to eradicate Gambusia, a serious invasive pest fish species, from a Tasmanian estuary.

The role of fat crystal wettability in altering dairy emulsion properties. The role of fat crystal wettability in altering dairy emulsion properties. This project aims to control fat crystal wettability, to create tailored dairy products with desirable stability, shelf-life and texture. Fat crystals are an essential component of dairy emulsions (fat droplets dispersed in dairy/milk serum) and control product processing, shelf life and texture.

The role of fat crystal wettability in altering dairy emulsion properties. This project aims to control fat crystal wettability, to create tailored dairy products with desirable stability, shelf-life and texture. Fat crystals are an essential component of dairy emulsions (fat droplets dispersed in dairy/milk serum) and control product processing, shelf life and texture. Their structuring role involves partial coalescence: the formation of complicated network structures of fat droplets. Unless fat crystals are partially wetted by water, they will not be present at the fat droplet interface, and partial coalescence will not occur. Expected outcomes are new dairy products with optimum stability and texture.Read moreRead less

The project aims to develop advanced new material for multilayered packaging with high oxygen and moisture barrier properties for cost effective packaging applications. Poly Products currently imports and uses some polymer as its key component for controlling barrier property of their food packaging. However, the new nanostructured material when sandwiched between less expensive materials in a multilayered packaging film will yield excellent barrier properties, leading to extended shelf life of different food products. The new smart material will generate significant material saving and replace the imported polymer, and will secure export market of the product in Asia -Pacific region.Read moreRead less
Cognitive and behavioural benefits of omega-3 fatty acid supplementation across the lifespan. The Australian Bureau of Statistics recently estimated that 7-19% of children have learning and behaviour problems associated with child ADHD. Concurrently, rates of dementia are rapidly increasing worldwide, currently costing the Australian government $6.6 billion pa, and it has been predicted that rates of dementia could double every 20 years. If omega-3 PUFA research can show benefits in cognition an ....Cognitive and behavioural benefits of omega-3 fatty acid supplementation across the lifespan. The Australian Bureau of Statistics recently estimated that 7-19% of children have learning and behaviour problems associated with child ADHD. Concurrently, rates of dementia are rapidly increasing worldwide, currently costing the Australian government $6.6 billion pa, and it has been predicted that rates of dementia could double every 20 years. If omega-3 PUFA research can show benefits in cognition and behaviour across the lifespan, this has potential benefit for fish oil products and their ability to enhance mental health and cognitive outcomes, thereby helping to lower the substantial social and health care costs associated with poor academic performance, mental illness and growing rates of dementia.Read moreRead less
