In-Depth Information
of our knowledge, there are neither studies explicitly measuring enhanced
bioremediation at the field scale due to chemotaxis nor predictive models for
expected enhanced degradation rates based on chemotactic parameters.
Adequate distribution of degradative bacteria in contaminated regions is para-
mount for effective in situ bioremediation. Bacterial chemotaxis is an important
transport mechanism that can help achieve this goal. Experimental studies have
shown that chemotaxis has the potential to enhance bioremediation, but appli-
cations at the field scale have yet to be demonstrated. Laboratory studies
combined with additional field-scale experiments are needed to verify that
chemotaxis does indeed stimulate in situ biodegradation.
