The fact that common sewage bacteria are denitrifiers makes it simple to create an appropriate environment for the denitrification process. All that is needed is the presence of nitrate, an electron donor (carbon source) and an anaerobic environment. A more specialized knowledge of species of bacteria is hardly necessary in most cases. Exceptions are where a special carbon source, such as methane, is used, as only very few bacteria can metabolize methane under anaerobic conditions.

Denitrifying bacteria can be identified according to the methods described in the Standard Methode (1985). Other are listed in Table 4.2.
