It fixes atmospheric nitrogen for crop use and produces other plant growth promoting substances
Azotobacter can create an anaerobic environment for the nitrogenase enzyme by encapsulating the enzyme in specialized structures called heterocysts, which are able to maintain low oxygen levels necessary for nitrogenase activity. Heterocysts have thickened cell walls that limit oxygen diffusion, allowing nitrogenase to function optimally under anaerobic conditions.
Nitrogen-fixing bacteria, like Rhizobium and Azotobacter, convert nitrogen gas into ammonia, which can be taken up by plants and used to support their growth. Some cyanobacteria and certain types of archaea are also capable of fixing nitrogen.
The bacteria that converts nitrogen gas into ammonia is known as nitrogen-fixing bacteria. Some examples of nitrogen-fixing bacteria include Rhizobium, Azotobacter, and Clostridium. These bacteria play a crucial role in the nitrogen cycle by making nitrogen available to plants.
These bacteria are called nitrogen-fixing bacteria, such as Rhizobium or Azotobacter, which convert atmospheric nitrogen gas into forms usable by plants, like ammonium or nitrates. This process is essential for plant growth as nitrogen is a crucial nutrient for their development.
Nitrogen-fixing bacteria are the ones in the soil that convert nitrogen gas into forms (ammonia, nitrites, nitrates) that plants can use for growth. Examples include Rhizobium, Azotobacter, and Cyanobacteria. These bacteria play a vital role in the nitrogen cycle and are commonly found in the root nodules of leguminous plants.
Azotobacter's cells are large rods, at least 2 microns in diameter

Azotobacter is a genus of free-living nitrogen-fixing bacteria that play a crucial role in the nitrogen cycle. They convert atmospheric nitrogen (N₂) into ammonia (NH₃) through the process of nitrogen fixation, which can then be utilized by plants for growth. Additionally, Azotobacter produces various bioactive compounds, such as vitamins and growth-promoting substances, enhancing soil fertility and promoting plant health. Their activity contributes to improving soil structure and nutrient availability, benefiting agricultural ecosystems.

nitrogen, are you stupid? You have to have a kid in 7th grade to answer your question? I think college may serve your education needs better than wiki answers.
The two main groups of bacteria responsible for nitrogen fixation are Rhizobium found in legume root nodules, and Azotobacter found in the rhizosphere of various plants. Rhizobium forms a mutualistic relationship with legumes, providing fixed nitrogen in exchange for sugars, while Azotobacter functions as a free-living nitrogen fixer in the soil.
Azotobacter can create an anaerobic environment for the nitrogenase enzyme by encapsulating the enzyme in specialized structures called heterocysts, which are able to maintain low oxygen levels necessary for nitrogenase activity. Heterocysts have thickened cell walls that limit oxygen diffusion, allowing nitrogenase to function optimally under anaerobic conditions.
Azotobacter, Rhizobium, Azospirillum, Phosphate solubilizing bacteria, and Mycorrhizal fungi are some examples of bio-fertilizers used to enhance soil fertility and plant growth.

Nitrogen-fixing bacteria, such as Rhizobium and Azotobacter, are needed to convert atmospheric nitrogen into a usable form like ammonia that plants can absorb. These bacteria form symbiotic relationships with plants or live freely in the soil.
Some bacteria in the soil, like Rhizobium and Azotobacter, are capable of converting nitrogen gas into a form that plants can use, such as ammonium or nitrates. This process is known as nitrogen fixation and is crucial for plant growth and soil fertility.
