denitrifying bacteria

denitrifying bacteria:

see nitrogen cyclenitrogen cycle,
the continuous flow of nitrogen through the biosphere by the processes of nitrogen fixation, ammonification (decay), nitrification, and denitrification. Nitrogen is vital to all living matter, both plant and animal; it is an essential constituent of amino acids,

Denitrifying Bacteria

bacteria that reduce nitrates to molecular nitrogen. Denitrifying bacteria include representatives of Pseudomonas, Achromobacter, Bacillus, and Micrococcus. All denitrifying bacteria are aerobes, and they can oxidize organic matter by means of atmospheric oxygen. However, when anaerobic conditions prevail, they use the oxygen of nitrates as an electron acceptor (“respiration by means of nitrates”). Denitrifying bacteria are grown on culture media with nitrates and an indicator that changes color when the nitrates are reduced. The bacteria are widespread in soil and in the water and soil of bodies of water.
