A microscopical examination of curdlan production by an Agrobacterium sp. We will investigate the secretion of the insoluble polysaccharide curdlan, a (1,3)-beta-glucan, from the surfaces of Agrobacterium cells and the assembly of the individual polysaccharide chains into microfibrils. Using state-of-the-art techniques in time lapse and electron microscopy we will compare the images of wild type curdlan-producing cells with those of mutants impaired in the production of curdlan. The outputs will ....A microscopical examination of curdlan production by an Agrobacterium sp. We will investigate the secretion of the insoluble polysaccharide curdlan, a (1,3)-beta-glucan, from the surfaces of Agrobacterium cells and the assembly of the individual polysaccharide chains into microfibrils. Using state-of-the-art techniques in time lapse and electron microscopy we will compare the images of wild type curdlan-producing cells with those of mutants impaired in the production of curdlan. The outputs will be information on the mechanics of curdlan production that will complement that emerging from our molecular biological and biochemical studies. These will have implications for understanding bacterial polysaccharide production in general and may have a commercial outcome in enhanced curdlan production.Read moreRead less
Investigating pathways of lipoglycan formation in the bacterial cell wall. This project aims to investigate how the complex cell walls of Mycobacteria and Corynebacteria are assembled. The project will utilise a combination of genetic, biochemical and advanced analytical approaches to investigate individual steps in the synthesis of key cell wall components and understand how the assembly of these components is coordinated with bacterial growth. Important outcomes of this research will be detail ....Investigating pathways of lipoglycan formation in the bacterial cell wall. This project aims to investigate how the complex cell walls of Mycobacteria and Corynebacteria are assembled. The project will utilise a combination of genetic, biochemical and advanced analytical approaches to investigate individual steps in the synthesis of key cell wall components and understand how the assembly of these components is coordinated with bacterial growth. Important outcomes of this research will be detailed information on processes that regulate the growth of bacteria with important biotechnology, veterinary and medical significance, as well as information on mechanisms of cell wall synthesis that may be conserved in all bacteria.Read moreRead less
