de·ni·tri·fi·ca·tion (de-ni″trĭ-fĭ-kaґshən) the setting free of gaseous nitrogen from nitrites and nitrates, as by certain soil bacteria, which results in depletion of nitrogen for plant growth. Denitrification carried out by aquatic bacteria can be beneficial in ridding waste waters of excess nitrates.
