Unlocking the potential of bacterial polymers by defining key determinants. Sugary structures that coat the surface of some bacteria, known as capsules, can be modified by bacterial viruses (bacteriophage) in the environment. For the bacterial genus Acinetobacter, this influences their use as naturally renewable 'green' biopolymers for remediating environments contaminated with petroleum hydrocarbons. This project aims to characterise crucial capsule polymerase enzymes using a combination of bio ....Unlocking the potential of bacterial polymers by defining key determinants. Sugary structures that coat the surface of some bacteria, known as capsules, can be modified by bacterial viruses (bacteriophage) in the environment. For the bacterial genus Acinetobacter, this influences their use as naturally renewable 'green' biopolymers for remediating environments contaminated with petroleum hydrocarbons. This project aims to characterise crucial capsule polymerase enzymes using a combination of bioinformatics and experimental methodologies to establish how bacteriophage influence Acinetobacter capsules. Outcomes include the development of an innovative genomics pipeline to detect capsule change, improving the use of living bacteria for bioremediation and sustainable rehabilitation of natural ecosystems.Read moreRead less
Unravelling a novel stress-signalling system in bacteria. This project aims to investigate the cyclic-di-AMP signalling system in industrially important bacteria. The recently discovered cyclic-di-AMP is essential for normal bacterial growth and plays key roles in heat and antibiotic resistance, metabolism and virulence. This project will develop new biological assays to shed light on how bacteria sense and respond to environmental stress. Expected outcomes include a much deeper understanding of ....Unravelling a novel stress-signalling system in bacteria. This project aims to investigate the cyclic-di-AMP signalling system in industrially important bacteria. The recently discovered cyclic-di-AMP is essential for normal bacterial growth and plays key roles in heat and antibiotic resistance, metabolism and virulence. This project will develop new biological assays to shed light on how bacteria sense and respond to environmental stress. Expected outcomes include a much deeper understanding of signalling inputs and outputs. This should lead to benefits such as guiding the improvement of bacterial strains used in food and biochemical biotechnological applications, and may provide the foundation for the development of novel antibiotics.Read moreRead less
YhcB, a crucial player in the control of bacterial cell envelope biogenesis. All life depends on a cell envelope to enclose the chemical reactions that make life possible. But how do cell envelopes grow? How each component of the cell envelope is incorporated into the envelope at the right amount and in the right time to prevent cell death, has been a longstanding question in bacteriology. Using a unique combination of high through put genetic screens and biochemical approaches, this project wil ....YhcB, a crucial player in the control of bacterial cell envelope biogenesis. All life depends on a cell envelope to enclose the chemical reactions that make life possible. But how do cell envelopes grow? How each component of the cell envelope is incorporated into the envelope at the right amount and in the right time to prevent cell death, has been a longstanding question in bacteriology. Using a unique combination of high through put genetic screens and biochemical approaches, this project will characterise a key regulator of cell envelope growth in Gram-negative bacteria. Knowledge arising from this research will provide insight into a fundamental process in bacteria, will develop new technology to probe protein interactions, and will provide novel avenues to solve infection in plants, humans and animals.Read moreRead less
