Remodelling encapsulin nanocages to help enhance plant carbon fixation. Nature has evolved mechanisms in microbial systems to improve photosynthetic efficiency by saturating the enzyme Rubisco with carbon dioxide. These carbon concentrating mechanisms are genetically complex, precluding successful introduction into crops. Our simpler approach is to use encapsulins, a new source of robust bacterial pore-containing nanocages made from a single gene.

Our simpler approach is to use encapsulins, a new source of robust bacterial pore-containing nanocages made from a single gene.

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.

Building a synthetic chemical synapse through harnessed stochasticity. At the molecular level, biology is noisy, and life has evolved a plethora of mechanisms to harness this noise for useful output. If we want to construct de novo living systems to learn more about biology and the origin of life, then we must not ignore noise. This project aims to apply a design philosophy that embraces randomness to construct an artificial chemical synapse. Expected outcomes include creating a blueprint for th ....Building a synthetic chemical synapse through harnessed stochasticity. At the molecular level, biology is noisy, and life has evolved a plethora of mechanisms to harness this noise for useful output. If we want to construct de novo living systems to learn more about biology and the origin of life, then we must not ignore noise. This project aims to apply a design philosophy that embraces randomness to construct an artificial chemical synapse. Expected outcomes include creating a blueprint for the next generation of more dynamic artificial cells, developing vital tools for the elucidation of principles in biophysics and systems biology, and deepening our understanding of how noisy molecular level events have downstream effects on macro-scale behaviours. Several international collaborations are involved.

Synthetic biology enables sustainable synthesis of precious chemicals, ranging from drugs to biomaterials. Using microbes, high production levels are usually attained by overexpressing the genes that make the desired product, but this simple approach often fails for antibiotics and other compounds that are toxic to microbes. Using synthetic biology this project builds genetic circuits enabling smart, just-in-time activation of target genes, which is pervasive in natural pathways. Using these circuits we will boost 1) the production of a valuable antibiotic and 2) calcite precipitation in self-healing concrete. This approach enables the biosynthesis of many other chemicals, leading to cleaner and greener bio-factories.Read moreRead less
