This project aims to develop a technological platform for the fabrication of miniaturised and flexible sensors that enable the quantitative detection of important bioactive compounds such as fatty acids and biogenic amines. By utilising multi-enzymatic reactions in solid phase and engineering task-specific inks, chemiresistive sensors will be printed seamlessly as a whole. The sensors will respond to complex target biomolecules via a series of enzymatic reactions through which the analyte will convert to much simpler, reactive and hence measurable molecules. This project will enable to design miniaturised sensors for point-of-care detection of biomolecules that cannot be yet evaluated by the end users.Read moreRead less

Transport phenomena in foam fractionation. Foam fractionation has a number of immediate applications in mineral and food processing but its most exciting potential is as low cost alternative for recovering and purifying high value biosurfactants. These are materials used to stabilise interfaces in living systems, and can be used as antibiotics and antiviral agents. The affinity for biosurfactants to collect at an interface suggests that foam fractionation is an ideal process to concentrate valua ....Transport phenomena in foam fractionation. Foam fractionation has a number of immediate applications in mineral and food processing but its most exciting potential is as low cost alternative for recovering and purifying high value biosurfactants. These are materials used to stabilise interfaces in living systems, and can be used as antibiotics and antiviral agents. The affinity for biosurfactants to collect at an interface suggests that foam fractionation is an ideal process to concentrate valuable products. Clearly, a cost-effective and reliable method of enriching streams of biosurfactants will make their use even more attractive and will engender the development of more novel biomaterials, such as pepfactants.Read moreRead less

Methane (biogas) has a large role to play in meeting the energy needs of the human race globally whilst reducing greenhouse gas emissions. Microbial communities are responsible for biogas production from non-renewable (coal) and renewable (food waste) resources. This project seeks to: increase biogas yields by redirecting electron flow towards biogas producing microbes using electrochemically active phenazines; understand the molecular mechanism by which phenazines increase biogas yields; and, assess the environmental consequence of phenazine application to coal seam gas production and anaerobic digestion of food waste. Phenazines are likely to emerge as a safe and cost-effective technology for improved biogas generation.Read moreRead less

This project aims to understand ultrasonic processing of concentrated slurries of oil-bearing yeast and algae. Humans must reduce their dependency on petroleum. While microorganisms can produce oils as replacement fuels and base chemicals, the processes for extracting these oils are inefficient. Ultrasound could improve oil recovery by replacing toxic solvents. Understanding the effects of ultrasound on microbial emulsions is expected to develop solvent-free oil recovery processes that improve the economic and environmental benefits of microbial oil production. Such processes would greatly increase the efficiency and reduce the cost of producing microbial oils that can be used as green alternatives to petroleum fuels and chemicals.Read moreRead less
