Abstract:
Positron Emission Tomography simultaneously monitored flow dynamics and in-situ microbial activity in opaque sediment columns. An 18F labelled electron donor, 2-deoxy-2-[18F]-fluoro-D-glucose (18FDG), was added to flowing columns containing sterile sediment, microbially active sediment and quartz sand. 18FDG accumulated in microbially active, glucose primed, sediment (105-106 cells g-1) at 10-16 mol g-1 (~40% of the 100 MBq spike) giving the first example of 18FDG uptake by indigenous microorganisms in a complex sediment system at flow rates representative of the shallow subsurface.
