Question

Role of azotobacter and nitrobacter in nitrogen cycle

Answer 1

Answer:

Nitrobacter cells are obligate aerobes and have a doubling time of about 13 hours.

Nitrobacter play an important role in the nitrogen cycle by oxidizing nitrite into nitrate in soil and marine systems.

Acetobacter is an obligatory aerobic, nitrogen-fixing bacteria that is known for producing acid as a result of metabolic processes.

While all nitrogen-fixing bacteria contain nitrogenase in order to utilize atmospheric nitrogen gas as a source for metabolic biosynthesis, different nitrogen-fixing microorganisms protect the oxygen-sensitive microorgansims from oxygen exposure in different ways.
