Discovery of new genes for plant cellulose biosynthesis and improved fibre production. Cellulose, the world's most abundant biopolymer, is important to the cotton and forest industries and for human and animal nutrition. Before biotechnology can manipulate cellulose, we must identify the enzymes of the synthesis pathway and understand how their properties determine the properties of the cellulose they produce. Not all enzymes are known and any relationships to cellulose properties remain unexplo ....Discovery of new genes for plant cellulose biosynthesis and improved fibre production. Cellulose, the world's most abundant biopolymer, is important to the cotton and forest industries and for human and animal nutrition. Before biotechnology can manipulate cellulose, we must identify the enzymes of the synthesis pathway and understand how their properties determine the properties of the cellulose they produce. Not all enzymes are known and any relationships to cellulose properties remain unexplored. This study extends our successful mutational analysis of cellulose synthesis in Arabidopsis and initiates the molecular analysis of organisms making cellulose with distinctive properties. It will significantly advance knowledge of cellulose biosynthesis and identify novel genes for fibre improvement.Read moreRead less
Flipping the mattress: infinite polyurethane recycling by synthetic biology. Australia is covered in billions of tonnes of plastic and yet <10% is recycled today. Polyurethane (PU) is ubiquitous in our everyday lives, from lacquer coatings to elastane clothing to durable foam padding in car seats, cushions and mattresses. Currently, there are few avenues for PU recycling and much ends up in landfill e.g., a single mattress produces 15-20kg of PU foam waste. Luckily, biodegradation of PU can occu ....Flipping the mattress: infinite polyurethane recycling by synthetic biology. Australia is covered in billions of tonnes of plastic and yet <10% is recycled today. Polyurethane (PU) is ubiquitous in our everyday lives, from lacquer coatings to elastane clothing to durable foam padding in car seats, cushions and mattresses. Currently, there are few avenues for PU recycling and much ends up in landfill e.g., a single mattress produces 15-20kg of PU foam waste. Luckily, biodegradation of PU can occur naturally via various microbial means and from insects, like Galleria mellonella larvae. The overall aim of this research project is to understand plastic biodegradation and translate nature’s solutions into flexible and efficient synthetic enzyme technologies that can sustainably recycle commonly used PU foams.

The molecular basis for oocyst and cyst wall formation in apicomplexan parasites. Apicomplexan parasites such as Eimeria, Neospora, Toxoplasma and Plasmodium are single celled organisms - protozoa - that cause some of the most serious infectious diseases of livestock and humans ever known. Transmission of these parasites is dependent on their ability to encase themselves in protective structures known as oocyst or cyst walls. These walls are resistant to harsh environmental conditions, chemicals ....The molecular basis for oocyst and cyst wall formation in apicomplexan parasites. Apicomplexan parasites such as Eimeria, Neospora, Toxoplasma and Plasmodium are single celled organisms - protozoa - that cause some of the most serious infectious diseases of livestock and humans ever known. Transmission of these parasites is dependent on their ability to encase themselves in protective structures known as oocyst or cyst walls. These walls are resistant to harsh environmental conditions, chemicals and attack by the immune system. We will discover and characterise the molecular basis for cyst wall formation. This fundamental knowledge will be the building block for new, highly specific drugs and vaccines to control these extremely important pathogens.Read moreRead less
