What is nitrification and denitrification?

Answer: 

• Ammonia is transformed by nitrification from nitrite to nitrate through the method of nitrification. Chemoautotrophic bacteria carry out the aerobic process
• Nitrosomonas and Nitrococcus helps in oxidising the ammonia to nitrite
• The reverse of nitrification is denitrification. Here, denitrifying microorganisms convert soil-based nitrate to nitrogen
• Pseudomonas and Thiobacillus are the 2 bacteria that are used for denitrifying
