Can cyanobacteria use organic nutrients to thrive in future oceans? Marine cyanobacteria are central to regulating the global climate and underpin entire marine food webs. Though they possess genes necessary to uptake diverse organic nutrients, we know very little about whether and how organic nutrients shape the physiology and ecology of cyanobacteria. Using our innovative high-throughput approach, this project aims to systematically characterise organic nutrient uptake in picocyanobacteria. O ....Can cyanobacteria use organic nutrients to thrive in future oceans? Marine cyanobacteria are central to regulating the global climate and underpin entire marine food webs. Though they possess genes necessary to uptake diverse organic nutrients, we know very little about whether and how organic nutrients shape the physiology and ecology of cyanobacteria. Using our innovative high-throughput approach, this project aims to systematically characterise organic nutrient uptake in picocyanobacteria. Our molecules-to-ecosystems approach expects to transform our understanding of alternate nutrient acquisition in cyanobacteria and how it may shape populations of these important photosynthetic organisms in a rapidly-changing ocean landscape.

Microbial junk food: developing synthetic platforms for plastic degradation. This project aims to establish the genetic basis of polyethelene biodegradation (PED) by microbes from the gut microbiome of plastic-eating caterpillars. It will transform the active microbial PED genes into carefully designed synthetic microbes for efficient, safe and large-scale PED. The project will combine innovative functional microbial genetic tools and synthetic biology techniques with solid biochemistry and bioi ....Microbial junk food: developing synthetic platforms for plastic degradation. This project aims to establish the genetic basis of polyethelene biodegradation (PED) by microbes from the gut microbiome of plastic-eating caterpillars. It will transform the active microbial PED genes into carefully designed synthetic microbes for efficient, safe and large-scale PED. The project will combine innovative functional microbial genetic tools and synthetic biology techniques with solid biochemistry and bioinformatics to produce translatable synthetic platforms containing key genes optimised for efficient PE waste removal. The outcomes will have the potential to transform the relative ineffective and expensive current methods for PE disposal into flexible, cost-effective and sustainable solutions applicable to multiple sectors.Read moreRead less
Biosynthetic Hooks for an Enigmatic Marine Toxin. This project aims to characterise the genetic basis for the production of tetrodotoxin; a potent neurotoxin of ecological and biomedical significance. We hypothesise that tetrodotoxin is produced by microorganisms and transferred via the food web to fish, molluscs and other marine animals. Our integrated genomic and synthetic biology approach, targeting key biosynthesis genes, will reveal pathways for the production of tetrodotoxin and other pote ....Biosynthetic Hooks for an Enigmatic Marine Toxin. This project aims to characterise the genetic basis for the production of tetrodotoxin; a potent neurotoxin of ecological and biomedical significance. We hypothesise that tetrodotoxin is produced by microorganisms and transferred via the food web to fish, molluscs and other marine animals. Our integrated genomic and synthetic biology approach, targeting key biosynthesis genes, will reveal pathways for the production of tetrodotoxin and other potentially valuable compounds. In addition to providing unprecedented insight into the ecology and biosynthesis of this enigmatic toxin, the data generated will enable improved management of seafood safety and provide a foundation for the future development of novel neuroactive compounds.Read moreRead less
