Summary
Annotating unknown microbial gene functions with organic matter change. This project intends to develop a new method for determining the function of microbial genomes. Microbes are all pervasive on Earth. It is now possible to routinely sequence microbial genomes. However, the function of most genes encoded on these genomes remains elusive, severely limiting our understanding of most ecosystems. This project seeks to develop new methods to assign function to uncharacterised genes, by correlating ....Annotating unknown microbial gene functions with organic matter change. This project intends to develop a new method for determining the function of microbial genomes. Microbes are all pervasive on Earth. It is now possible to routinely sequence microbial genomes. However, the function of most genes encoded on these genomes remains elusive, severely limiting our understanding of most ecosystems. This project seeks to develop new methods to assign function to uncharacterised genes, by correlating changes in metabolite abundance with gene expression in a model permafrost thaw peatland. Determining the function of uncharacterised genes has widespread implications for microbial ecology and its numerous real-world applications, from determining soil greenhouse gas emissions to understanding human intestinal flora.Read moreRead less
In situ remediation in mine site rehabilitation. In situ remediation in mine site rehabilitation. By enhancing and guiding abiotic and biotic processes of soil development, this project aims to accelerate the in situ remediation of bauxite residue (alumina refining tailings). Over 7 gigatonnes of tailings are produced globally every year, comprising complex mineral assemblages at extremes of pH and salinity with minimal biological activity. This project will build detailed knowledge on the chemi ....In situ remediation in mine site rehabilitation. In situ remediation in mine site rehabilitation. By enhancing and guiding abiotic and biotic processes of soil development, this project aims to accelerate the in situ remediation of bauxite residue (alumina refining tailings). Over 7 gigatonnes of tailings are produced globally every year, comprising complex mineral assemblages at extremes of pH and salinity with minimal biological activity. This project will build detailed knowledge on the chemical, physical, and biological properties of bauxite residue and apply this to develop field-scale in situ remediation strategies. This research will also advance understanding of soil development and primary succession of microbial communities in extreme, anthropogenic environments such as those presented by tailings.Read moreRead less
