With our Nitrification analysis, the microbial potential for nitrification is determined in your sample. On request we can give you advice on stimulating, preventing or managing nitrification processes for your specific situation.

Analysis essentials

  • To determine the potential for nitrification
  • To monitor the potential for the nitrification process in time (does it increase or decrease?)

Content of the package

The following microbial key parameters are detected and quantified with our Nitrification analysis:

  • A gene specific for the first step in bacterial nitrification (ammonium oxidation), bacterial ammonium monooxygenase
  • A gene specific for the first step in archaeal nitrification (ammonium oxidation), archaeal ammonium monooxygenase

Background information

Nitrification is the two-step biological oxidation of ammonia to nitrate, with nitrite as intermediate product. The process occurs only in the presence of oxygen by nitrifying bacteria, or nitrifiers. Nitrification is very important for the nitrogen cycle in the soil and is also used in waste water treatment for the removal of ammonia. It is desirable to remove ammonia before discharging it in the environment because of the toxic effects for aquatic organisms. In the process, ammonia (present in the sewers) is converted to nitrate. Nitrate is subsequently converted to nitrogen gas by another process, called denitrification. The nitrifying bacteria need specific conditions to optimally convert ammonia to nitrite and nitrate, for example appropriate pH, oxygen, temperature and nutrients. Selecting the right conditions will stimulate the nitrification process and increase the rate of ammonium removal.
