Biofilm development by bacteria
Bacteria predominantly exist in the environment as surface associated communities, called biofilms, which protect them from stresses including oxidative stress, UV exposure, antibiotics, the host immune response and predation. There is an emerging genetic program that underpins biofilm development, and bacteria within biofilms express unique genes that are not normally expressed in planktonic cells. Biofilm development is driven by a complex regulatory program involving intra- and extra-cellular signalling molecules, physiological responses to nutritional cues as well as environmental cues (e.g. temperature, salinity), and responses to predators. Biofilms are responsible for > 65% of all infections, including chronic infections as well as infection associated with indwelling biomedical devices and fouling of industrial surfaces such as water purification membranes.
The study of biofilm development offers unique opportunities to investigate a fundamental adaptive strategy of bacteria as well as to develop novel methods for the control of biofilm formation in medical, industrial and environmental contexts. For example, we have identified antagonists of cell-cell signalling molecules that block biofilm development and have also shown that nitric oxide acts as an intracellular signal, via cyclic-di-GMP, to control biofilm development in bacteria. Biofilm control for medical and industrial applications are being developed based on these signalling systems. Therefore, my research platform is multidisciplinary in nature in order to develop a complete understanding of the genetics, physiology, biochemistry, inter-kingdom interactions and signalling, medical and evolutionary aspects of biofilm development.
