What's the difference between nitrification and dentification
Y_Kistochka [10]

Difference between nitrification and dentrification

Explanation:

Nitrification and denitrification are part of the nitrogen cycle

Nitrification is the process of conversion of ammonium to nitrate by nitrifying bacteria like Nitrobacter and Nitrosomonas

Denitrification is the process of reduction of nitrate to nitrogen gas by denitrifying bacteria like Pseudomonos, Lactobacillus etc.

Nitrifying bacteria are autotrophs and grows slowly and need aerobic condition.  Denitrifying bacteria are hetertrophs and grows rapidly and need anaerobic conditions.

Nitrification requires a pH of about 6.5 to 8.0; denitrification takes place at 7.0 to 8.5

Nitrification provides soluble nitrates readily available in the soil to be easily absorbed by the roots.

Denitrification processes are used in wastewater or effluent treatment plants.
