The discovery of 'cable bacteria' which can couple redox half reactions cm distant from one another by
transporting electrons along their filaments has fundamentally changed the way we view sediment
biogeochemistry. This project will investigate the interaction between 'cable bacteria' and enhanced nitrogen
recycling in seasonally anoxic estuaries. The new understadning created from this project will help us better
understand how nitrogen is retained in seasonally estuaries which is essential to combatting the problem of
eutrophication. In addition the fundamental new understanding of the ecology and biogeochemical processes
mediated by 'cable bacteria', may lead to future applications in waste water treatment.
