Deriving products from all levels of the agricultural production chain to achieve zero-waste, greatly increases profitability and optimises sustainability. In the meat industry, new opportunities are opening to use by-products such as tallow for the production of novel, cleaner energy-producing biodiesel fuel by way of cutting-edge technologies. Production by these technologies greatly enhances cost benefits, fuel properties and energy security. In this proposal we will partner with a large South Australian regional abattoir and rendering facility to develop these technologies initially at the laboratory scale, and then up-scaling to pilot and full production levels.

Multi-Scale Fermentation Facility for Beverage Research. Australia's largest concentration of beverage fermentation research effort and infrastructure is arguably represented by the University of Adelaide and partners at the Waite Campus, particularly The Australian Wine Research Institute and Provisor Pty Ltd.

Australia's largest concentration of beverage fermentation research effort and infrastructure is arguably represented by the University of Adelaide and partners at the Waite Campus, particularly The Australian Wine Research Institute and Provisor Pty Ltd. This cluster seeks to establish an integrated, jointly managed, Multi-Scale Fermentation Facility for Beverage Research. This Facility will address critical shortages in fermentation capacity for research (volumes between 1 ml and 1000 L), offer a vertically integrated system to facilitate step-wise scale-up, allow more accurate modelling of industrial fermentations, enable greater adoption of high-throughput formats and technologies, and achieve enhanced productivity through increased system automation.Read moreRead less
Ex vivo production of neutrophils. Relentless infections frequently occur in patients receiving intensive chemotherapy treatment. Chemotherapy is toxic to the bone marrow where blood cells are produced. A low white blood cell count and in particular a low neutrophil count is linked with infection in these patients. Unlike red cells and platelets, neutrophils are difficult to collect from blood donors and hence are not routinely available. In this project, we will develop a practical, cost effic ....Ex vivo production of neutrophils. Relentless infections frequently occur in patients receiving intensive chemotherapy treatment. Chemotherapy is toxic to the bone marrow where blood cells are produced. A low white blood cell count and in particular a low neutrophil count is linked with infection in these patients. Unlike red cells and platelets, neutrophils are difficult to collect from blood donors and hence are not routinely available. In this project, we will develop a practical, cost efficient process for the production of neutrophils from cord blood. Transfusion of these neutrophils should reduce the chance of patients suffering serious infection, allow them to recover faster from their chemotherapy, and reduce the need for admission to intensive care.Read moreRead less
EX VIVO PRODUCTION OF MATURE RED BLOOD CELLS FOR TRANSFUSION. This project aims to establish a practical, cost efficient biotechnology platform for the expansion and maturation of blood stem cells to produce blood transfusion products. Red blood cell production will be used as the prototype model. It is envisaged that blood bioreactors will initially supplement and ultimately replace the current blood donor based process, thus overcoming the on-going donor recruitment, retention and safety issue ....EX VIVO PRODUCTION OF MATURE RED BLOOD CELLS FOR TRANSFUSION. This project aims to establish a practical, cost efficient biotechnology platform for the expansion and maturation of blood stem cells to produce blood transfusion products. Red blood cell production will be used as the prototype model. It is envisaged that blood bioreactors will initially supplement and ultimately replace the current blood donor based process, thus overcoming the on-going donor recruitment, retention and safety issues associated with collection of single units of blood. This project is focused on providing solutions to two key technical and economical challenges: (a) achieving full maturation of red blood cells and (b) achieving at least a 100-fold intensification of the expansion and maturation process through perfusion.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.

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

Lactic acid is the most widely occurring multifunctional organic acid. It has enormous applications in food and food-related industries, and great potential use for production of biodegradable and biocompatible polylactate polymers. The aim of this research is to develop an innovative biotechnological process, incorporating simultaneous saccharification and fermentation, which integrates the production of lactic acid with the treatment of high strength food industry ?effluent? streams - carbohydrate waste streams. The proposed SSF process will cultivate an identified fungal Rhizopus sp strain on the waste streams, as production substrates, leading to an environmentally friendly and economically sustainable new technology for the food industry.Read moreRead less
Exploiting novel yeast attributes to produce industrial strains with better fermentative and processing qualities. Food and beverage fermentations are problematic processes, largely due to limitations of the yeast being used. This laboratory has indentified in individual yeast strains highly desirable fermentative characteristics or else the ability to over-produce compounds that benefit product processing.

Food and beverage fermentations are problematic processes, largely due to limitations of the yeast being used. This laboratory has indentified in individual yeast strains highly desirable fermentative characteristics or else the ability to over-produce compounds that benefit product processing. Pursuing the commercial potential of these findings is the specific objective of this proposal. Thus we will extend our collaboration with Coopers Brewery through this new project area with the aims of a) producing optimised, hybrid (non-GMO) strains with combinations of desirable fermentation properties, b) develop novel processing or quality-enhancing treatments while c) generating a high caliber PhD graduate with extensive industry experience.Read moreRead less
Algal direct-air CO2 capture through interfacial enzyme immobilisation . Capturing CO2 directly from the atmosphere is challenging due to inherently slow mass transfer kinetics. This project aims to overcome this using an enzyme that can rapidly solubilise CO2 from air into water, to produce algae. By engineering the enzyme immobilisation at the air-water interface, this project will activate and protect the enzymes, increasing their lifespan and reducing costs.

Capturing CO2 directly from the atmosphere is challenging due to inherently slow mass transfer kinetics. This project aims to overcome this using an enzyme that can rapidly solubilise CO2 from air into water, to produce algae. By engineering the enzyme immobilisation at the air-water interface, this project will activate and protect the enzymes, increasing their lifespan and reducing costs. By understanding mass transfer and enzyme activity in the interfacial immobilisation media, floating enzyme rafts can be developed for deployment over expansive areas, facilitating large-scale conversion of atmospheric CO2 into algae-derived fuels, feeds and chemicals.Read moreRead less
