Electron transport catalysis in organohalide pollutant respiration. This project aims to understand the link between substrate specificity and gene sequence of dehalogenating enzymes in organohalide respiring bacteria (ORB) and the mechanism by which electrons are transferred to dehalogenating enzymes through protein-protein interactions. Organohalides were present in Earth's early history and now pollute the environment globally. Organohalide respiring bacteria (ORB) can degrade these pollutant ....Electron transport catalysis in organohalide pollutant respiration. This project aims to understand the link between substrate specificity and gene sequence of dehalogenating enzymes in organohalide respiring bacteria (ORB) and the mechanism by which electrons are transferred to dehalogenating enzymes through protein-protein interactions. Organohalides were present in Earth's early history and now pollute the environment globally. Organohalide respiring bacteria (ORB) can degrade these pollutants by using them as terminal electron acceptors in their respiratory metabolism. This represents one of the most ancient respiratory systems on Earth about which little is known. This project will add to our fundamental knowledge of microbial evolution and metabolic systems, and pave the way for next generation organohalide remediation technologies.Read moreRead less
Contribution of Comammox Process to Sustainable Wastewater Treatment. This project aims to understand the versatility, activity and physiological features of comammox bacteria, the newly-discovered complete nitrifiers, in Australian wastewater treatment systems, and to model and evaluate their contributions to biological nitrogen removal process. Nitrogen transformations are crucial microbial processes in the wastewater treatment ecosystems, with nitrification largely responsible for ammonium ox ....Contribution of Comammox Process to Sustainable Wastewater Treatment. This project aims to understand the versatility, activity and physiological features of comammox bacteria, the newly-discovered complete nitrifiers, in Australian wastewater treatment systems, and to model and evaluate their contributions to biological nitrogen removal process. Nitrogen transformations are crucial microbial processes in the wastewater treatment ecosystems, with nitrification largely responsible for ammonium oxidation but comammox previously overlooked. The expected outcomes will develop new knowledge on the comammox process and provide novel insight and technological solution to refine strategies to manipulate nitrification processes for achieving improved biological nitrogen removal and sustainable wastewater management.Read moreRead less
