Integrating electrophysiology and molecular biology to understand the role of cell membranes in bacterial responses to chill and osmotic stress. Modern food manufacture is driven by competing demands: consumers prefer foods that are 'natural', i.e. having received minimal processing and containing less preservatives, and last, but are safe. Thus, a challenge is to find minimal sets of treatments and preservatives that limit microbial growth.

Modern food manufacture is driven by competing demands: consumers prefer foods that are 'natural', i.e. having received minimal processing and containing less preservatives, and last, but are safe. Thus, a challenge is to find minimal sets of treatments and preservatives that limit microbial growth.
Current methods to for determining limits to microbial growth are time and consuming and empirical. We will assess the potential of a new method (MIFE) to rapidly measure limits of bacterial growth under combinations of treatments. At the same time we will study how cells, and in particular how the cell membrane, responds to these stresses to provide insights for the development of new, minimal - yet safe - food preservation technologies.

Understanding algal bloom microbiome function to improve seafood safety. Current phytoplankton ecological theory is derived primarily from lab cultures, but in nature phytoplankton have unique microbiomes that support their growth and ongoing ocean primary production. This project aims to establish the structure and function of these natural microbiomes, and how they contribute to seafood poisoning caused by bacteria and algal biotoxins. Using advanced flow cytometry with single-cell microbial ....Understanding algal bloom microbiome function to improve seafood safety. Current phytoplankton ecological theory is derived primarily from lab cultures, but in nature phytoplankton have unique microbiomes that support their growth and ongoing ocean primary production. This project aims to establish the structure and function of these natural microbiomes, and how they contribute to seafood poisoning caused by bacteria and algal biotoxins. Using advanced flow cytometry with single-cell microbial profiling, we will sample nano-scale plankton microbiomes and synthetic microbiome phylogenomics to the link between microbiomes and seafood poisoning outbreaks. The outcomes will underpin enhanced predictive modelling of seafood risk to ensure the safety and export security of Australia's $2 billion seafood industry.Read moreRead less
Supporting or sabotaging sustainable development? State policy responses to environmental certification schemes. Almost everywhere, forests and fisheries are experiencing degradation and biodiversity loss. Since 1990, governments, industry and civil society organizations have expressed growing interest in market-based instruments for environmentally sustainable development. However, while states support the use of market-based instruments in general, serious problems arise with specific schemes. ....Supporting or sabotaging sustainable development? State policy responses to environmental certification schemes. Almost everywhere, forests and fisheries are experiencing degradation and biodiversity loss. Since 1990, governments, industry and civil society organizations have expressed growing interest in market-based instruments for environmentally sustainable development. However, while states support the use of market-based instruments in general, serious problems arise with specific schemes. This is particular true of environmental certification schemes, several of which have been opposed. Our study will explore the underlying factors that shape government responses to certification schemes in the forestry and fisheries sectors, thereby providing practical policy advice to ensure state institutions support rather than sabotage environmentally sustainable development.Read moreRead less
