de·ni·tri·fi·ca·tion

(dē-nī'tri-fi-kā'shŭn),
1. Removal of nitrogen from any material or chemical compound; especially from the soil, as by certain (denitrifying) bacteria that render the nitrogen unavailable for plant growth.
2. Withdrawal of nitrogen from soil by plant growth.
Synonym(s): denitration

denitrification

the process by which nitrogenous compounds are degraded and nitrogen is returned to the air in gaseous form, e.g. the breaking down of nitrates and nitrites to gaseous nitrogen, carried out in the absence of oxygen by soil bacteria. The process is associated with waterlogged soils and low fertility. See NITROGEN CYCLE.

Nitrate removal from natural watercourses as well as from artificially straightened and channelized drainage systems occurs through biotic uptake of nitrogen into plant and/or microbial cellular tissue, denitrification, and/or dissimilatory nitrate reduction.
Ecology of denitrification and dissimilatory nitrate reduction to ammonium.
Dissimilatory nitrate reduction occurs when microorganisms use nitrate as an electron acceptor during respiration (Bonin 1996).
