abstract = {Bioremediation is a cost-efficient cleanup technique that
involves the use of metabolically active bacteria to degrade
recalcitrant pollutants. To further develop this technique
it is important to understand the migration and deposition
behavior of metabolically active bacteria in unsaturated
soils. Unsaturated transport experiments were therefore
performed using Deinococcus radiodurans cells that were
harvested during the log phase and continuously supplied
with nutrients during the experiments. Additional
experiments were conducted using this bacterium in the
stationary phase. Different water saturations were
considered in these studies, namely 100 (only stationary
phase), 80, and $40\%.$ Results from this study clearly
indicated that the physiological state of the bacteria
influenced its transport and deposition in sands.
Metabolically active bacteria were more hydrophobic and
exhibited greater deposition than bacteria in the stationary
phase, especially at a water saturation of $40\%.$ The
breakthrough curves for active bacteria also had low
concentration tailing as a result of cell growth of retained
bacteria that were released into the liquid phase. Collected
breakthrough curves and deposition profiles were described
using a model that simultaneously considers both chemical
attachment and physical straining. New concepts and
hypotheses were formulated in this model to include
biological aspects associated with bacteria growth inside
the porous media.},
