Abstract

Denitrification is a form of anaerobic bacterial respiration during which nitrogen (N) oxides, principally nitrate and nitrite, are reduced sequentially through NO and N2O to N2. The commonly accepted reductive pathway for denitrification is as follows:
$$ \begin{array}{*{20}{c}} {( + 5)} \\ {N{O_3}} \\ {Nitrate} \\ \end{array} \to \begin{array}{*{20}{c}} {( + 3)} \\ {N{O_2}} \\ {Nitrite} \\ \end{array} \to \begin{array}{*{20}{c}} {( + 2)} \\ {NO} \\ {Nitric\;oxide} \\ \end{array} \to \begin{array}{*{20}{c}} {( + 1)} \\ {{N_2}O} \\ {Nitrous\;oxide} \\ \end{array} \to \begin{array}{*{20}{c}} {(0)} \\ {{N_2}} \\ {Dinitrogen} \\ \end{array} $$
