Very Short Answer Question:
What is denitrification?
उत्तर
Denitrification is the process in which anaerobic bacteria convert soil nitrates back into nitrogen gas.
Denitrifying bacteria removes fixed nitrogen i.e. nitrates from the ecosystem and returns it to the atmosphere in an inert form.
Denitrifying bacteria include Bacillus spp., Paracoccus spp. and Pseudomonas denitrificans. They transform nitrates to nitrous and nitric oxides and ultimately to gaseous nitrogen.
2NO3 → 2NO2 → 2NO → N2
