Question

What is nitrification and denitrification ?​

Answer 1

Answer:

Nitrification: This is the step in the process of nitrogen fixation. The ammonia is converted to nitrates and then eventually to nitrites. The conversion is performed by the bacteria of the species Nitrosomonas.

Denitrification: This is the process which is the last step of nitrogen cycle. The nitrates are converted back to atmospheric nitrogen. This conversion is performed by the bacteria Pseudomonas.

Answer 2

Answer:

Simultaneous nitrification–denitrification is a wastewater treatment process. Microbial simultaneous nitrification-denitrification is the conversion of the ammonium ion to nitrogen gas in a single bioreactor.
