Stikstofassimilatie; stikstof wordt gebruikt om organische stoffen (aminozuren/eiwitten) te
vormen
Ammonificatie; bacteriën dissimileren afbraakproducten van eiwitten tot ammoniak
Nitrificatie; ammonium + zuurstof omgezet in nitriet, die nitriet + zuurstof omgezet in nitraat
Denitrificatie; bacteriën zetten nitraat-ionen om in gasvormige stikstof (N2)
Meeste planten groeien niet op stikstofarme bodem
Stikstofbinding/stikstoffixatie; bacteriën met enzym nitrogenase splitst stikstofmoleculen in
twee stikstofatomen, die binden aan waterstofatomen > ammoniak ontstaat
