Some microorganisms that can fix atmospheric nitrogen include:
1. Rhizobium: This is a genus of bacteria that forms a symbiotic relationship with leguminous plants, such as soybeans and clover. The bacteria colonize the roots of these plants and convert atmospheric nitrogen into a form that the plants can use for growth.
2. Azotobacter: This is a genus of free-living bacteria that can fix atmospheric nitrogen. They are commonly found in soil and can contribute to the nitrogen cycle by converting atmospheric nitrogen into a usable form for plants.
3. Cyanobacteria: These are a group of photosynthetic bacteria that can fix atmospheric nitrogen. They are commonly found in aquatic environments, such as lakes and oceans, and play a crucial role in nitrogen fixation in these ecosystems.
4. Frankia: This is a genus of bacteria that forms a symbiotic relationship with certain plants, such as alder and casuarina. The bacteria colonize the roots of these plants and fix atmospheric nitrogen, providing a source of nitrogen for the plants.
5. Anabaena: This is a genus of filamentous cyanobacteria that can fix atmospheric nitrogen. They are commonly found in freshwater environments and can form symbiotic relationships with certain plants, such as water ferns.
These are just a few examples of microorganisms that can fix atmospheric nitrogen. There are many other bacteria and archaea that have the ability to perform nitrogen fixation.
