Asked by: John Coles
They express a nitrogenase enzyme that combines the gaseous, atmospheric nitrogen with hydrogen to produce ammonia. Ammonia is a useful biological molecule as it is an essential part of molecules such as amino acids. The bacteria receive carbohydrates from the legumes in return for the production of ammonia.
What is the role of microorganisms in nitrogen cycle?
Microorganisms play an important role in improving soil fertility and involved in all aspects of N cycling, including N2 fixation, nitrification, denitrification and ammonification. They decompose plant residues, soil organic matter and release inorganic nutrients that can then be taken up by plants.

What microorganisms are involved in the nitrogen cycle?
It is becoming clear that denitrifying fungi, nitrifying archaea, anammox bacteria, aerobic denitrifying bacteria and heterotrophic nitrifying microorganisms are key players in the nitrogen cycle.

What are microorganisms function?
Microorganisms are useful in producing foods, treating waste water, creating biofuels and a wide range of chemicals and enzymes. They are invaluable in research as model organisms. They have been weaponised and sometimes used in warfare and bioterrorism.
