Elucidating the genetic basis of newly evolved metabolic functions in yeast. This project intends to research how complex metabolic pathways originate and evolve. This project will use cutting edge genome sequencing and molecular techniques to elucidate the heritable genetic basis of Baker’s yeast, which has been the selectively evolved to use xylose as a sole carbon source: something vital for second generation biofuel production that wild yeast cannot do. This project will combine detailed molecular characterisation of highly adapted yeast strains with a novel "molecular palaeontology" approach to trace the evolutionary process and identify functionally significant loci under selection. Detailed characterisation of this trait will accelerate the development of future yeast strains and test fundamental evolutionary theories.Read moreRead less

This project aims to improve the efficiency of advanced single-celled green algae (microalgae) production systems which can produce a wide range of high-value products including renewable fuels and animal feeds. Such systems are able to expand photosynthetic capacity onto non-arable land using carbon dioxide and saline water. However, production efficiencies and costs are currently limited by the ability to capture and distribute light through these systems effectively. This project aims to optimise methods of light delivery and distribution through photo-bioreactors and high rate ponds. This knowledge is intended to be integrated into advanced modelling tools to enable model-guided design of next-generation high-efficiency systems.Read moreRead less

The development of hard carbon anode materials for stationary rechargeable sodium and potassium ion batteries remains a major technological challenge. This project aims to utilise two very different biomass feedstock sources, sorghum and macadamia shell agricultural waste to manufacture low-cost, high-performance carbon anodes. Current carbon anode materials such as graphite or carbonised sucrose, pitch or phenolics suffer from poor performance, high cost and/or low carbon yield and device durability issues. This project will investigate combinations of biomass precursors, tailored graphene and carbon alloys in order to significantly enhance anode performance while minimising cost.Read moreRead less
Transforming residues from meat processing into engineered soil amendments. The aim of this project is to transform organic residues from meat processing into agricultural soil amendments that actively improve nutrient retention and reduce nitrous oxide (a potent greenhouse gas) emissions. Current disposal and treatment options for meat processing residues are economically and environmentally unsustainable. In this research, a modified hydrothermal carbonisation process will be developed to tran ....Transforming residues from meat processing into engineered soil amendments. The aim of this project is to transform organic residues from meat processing into agricultural soil amendments that actively improve nutrient retention and reduce nitrous oxide (a potent greenhouse gas) emissions. Current disposal and treatment options for meat processing residues are economically and environmentally unsustainable. In this research, a modified hydrothermal carbonisation process will be developed to transform organic residues into novel hydrochars. The influence of these hydrochars on soil nutrient retention and nitrous oxide production will then be assessed using stable isotope tracing, genetic characterisation, and numerical modeling. The project will reduce the economic and environmental costs of organic waste disposal.Read moreRead less
Halophytes for high-saline agriculture: optimising performance and understanding physiology. The recent drought has shaved off up to 1 per cent of Australia's economic growth and resulted in losses of over $6 billion in crop and livestock production. At the same time, very large volumes of water with impaired chemical quality are generated by industry and municipal water treatment processes. In most cases, these cannot be used directly for crop irrigation and have to be disposed of at extreme co ....Halophytes for high-saline agriculture: optimising performance and understanding physiology. The recent drought has shaved off up to 1 per cent of Australia's economic growth and resulted in losses of over $6 billion in crop and livestock production. At the same time, very large volumes of water with impaired chemical quality are generated by industry and municipal water treatment processes. In most cases, these cannot be used directly for crop irrigation and have to be disposed of at extreme cost and waste. This project will utilise halophytes as 'alternative cash crops' to use the saline water produced by the coal seam gas operations in the Surat Basin area in Queensland. This will result in a saving of at least $48 million over the five years of operation.Read moreRead less
How to make antibiotics in pig feed redundant, naturally. Antimicrobial resistance has become a major issue in human and veterinary medicine being partially caused by the use of in-feed antimicrobials in farm animals. This project aims to completely eliminate antimicrobials from piglet feeds. The key differential approach is based on helping the physiology of the animal rather than testing interventions against bacteria. The project will consist of developing a novel nutritional strategy of natu ....How to make antibiotics in pig feed redundant, naturally. Antimicrobial resistance has become a major issue in human and veterinary medicine being partially caused by the use of in-feed antimicrobials in farm animals. This project aims to completely eliminate antimicrobials from piglet feeds. The key differential approach is based on helping the physiology of the animal rather than testing interventions against bacteria. The project will consist of developing a novel nutritional strategy of naturally (through maternal conditioning) boosting the natural appetite and the capacity to digest in piglets early in life. The anticipated outcome is that the new peri-natal program will result in minimal bacterial proliferation and diarrhoea thus, negating the need for in-feed antimicrobials in piglets.
