Functional characterisation of poly-histidine triad proteins. This project aims to understand the role and function of a novel family of surface proteins produced by Streptococci. These so-called polyhistidine triad proteins are known to contribute to capacity to cause disease in animals and humans, but we need to know how they work, as they may be excellent targets for novel drugs or vaccines.
Novel perspectives on the function of AB5 toxin B subunits in pathogenic bacterial. AB5 toxins are produced by bacteria that cause important diseases in humans and livestock. This project tests the hypothesis that the components of the toxins responsible for binding to host cells and tissues also directly contribute to cellular damage, thereby providing a better understanding of how AB5 toxin-producing bacteria cause disease.
The Impact Of The Neonatal Gut Microbiome On Specific And Nonspecific Vaccine Responses.

Summary
Humans are colonised by a large and diverse group of microorganisms, collectively known as the microbiome. The gut microbiome, in particular, hosts an enormous abundance and diversity of bacteria, which perform a range of essential beneficial functions. Our study will investigate whether disruption of the gut microbiome in newborns, for example through antibiotic usage or maternal diet, leads to an impairment of subsequent immune responses to childhood immunisations.
A single vaccine for influenza and pneumonia. Influenza and bacterial pneumonia collaborate to kill millions of people each year. This project aims to develop a single vaccine that will provide long-lasting protection against both influenza and pneumonia.
Investigating The Antimicrobial Activity Of Zinc At The Host-pneumococcal Interface

Summary
Streptococcus pneumoniae is a human-only bacterium that is responsible for killing more than one million people every year. This project will analyse how the human immune system fights this bacterium, and subsequently, how the bacteria manages to subvert these attacks and survive in the human host. This will provide crucial information for developing new drugs against this pathogen, in an attempt to combat the ever-increasing problem of antibiotic resistance.
Bacterial glycan biosynthesis. This project aims to understand bacterial glycan biosynthesis. Bacteria produce complex polysaccharides, such as O antigens, critical to their interactions with their environment. Bacterial polysaccharides are used as vaccines, lubricants in oil drilling and food gelling agents. This project aims to find out how membrane proteins work together by using molecular genetic and biochemical approaches to identify amino acids in proteins that affect their interaction and ....Bacterial glycan biosynthesis. This project aims to understand bacterial glycan biosynthesis. Bacteria produce complex polysaccharides, such as O antigens, critical to their interactions with their environment. Bacterial polysaccharides are used as vaccines, lubricants in oil drilling and food gelling agents. This project aims to find out how membrane proteins work together by using molecular genetic and biochemical approaches to identify amino acids in proteins that affect their interaction and O antigen polymerisation. This project will create fundamental knowledge on mechanisms in polysaccharide biosynthesis and improve processes that produce and use bacterial polysaccharides, building intellectual property that can be commercialised for the benefit of society.Read moreRead less
Use of Organic Residues in Edible Mushroom Production. The aims are to develop growth and casing materials for mushroom production based on organic wastes. Casing peat is the most expensive raw ingredient used in mushroom production and there are major concerns over supply due to increasing environmental concerns in supplier countries and quarantine issues such as the recent foot and mouth outbreak in Europe. This project will develop alternatives to imported peats as casing materials and invest ....Use of Organic Residues in Edible Mushroom Production. The aims are to develop growth and casing materials for mushroom production based on organic wastes. Casing peat is the most expensive raw ingredient used in mushroom production and there are major concerns over supply due to increasing environmental concerns in supplier countries and quarantine issues such as the recent foot and mouth outbreak in Europe. This project will develop alternatives to imported peats as casing materials and investigate a range of organic residues which can be used as basic growth media for button and exotic mushrooms. This will increase the viability and sustainability of the mushroom industry in Australia.Read moreRead less
The molecular basis of zinc toxicity to Gram-positive bacteria. Gram-positive bacteria are a major cause of infectious diseases in both developed and developing countries. This project will contribute to our understanding of how zinc causes toxicity to these bacteria and facilitate our exploitation of this Achilles heel, by providing new insights into fundamental aspects of microbial physiology.
Novel technologies for biodiesel production from meat processing waste streams. 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 p ....Novel technologies for biodiesel production from meat processing waste streams. 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.

Summary
Hepatitis C virus (HCV) is a serious viral pathogen that causes significant liver disease. This proposal plans to examine how two proteins from the HCV, core and NS5A, interact with host proteins and pathways to facilitate viral replication and release of HCV; two processes that are poorly understood. Specifically we will tag viral proteins to allow us to investigate the HCV life cycle in living cells and determine the role of core and NS5A in facilitating HCV replication. This proposal may unco ....Hepatitis C virus (HCV) is a serious viral pathogen that causes significant liver disease.
