During nitrogen fixation, primarily nitrogen gas (N₂) from the atmosphere is converted into ammonia (NH₃) by certain bacteria and archaea, including those in symbiotic relationships with plants (like legumes) and free-living bacteria. However, in some processes associated with nitrogen fixation, especially in the specific conditions of certain bacteria, other gases can be produced as byproducts.
For example:
1. **Oxygen (O₂)** - In some cases, particularly in cyanobacteria, oxygen can be produced as a byproduct of photosynthesis occurring simultaneously with nitrogen fixation.
2. **Nitrous oxide (N₂O)** - This can be produced as an intermediate during the process of denitrification, which is related to nitrogen cycles but is different from nitrogen fixation itself. It can occur in some nitrogen-fixing systems, especially under anoxic conditions.
3. **Ammonia (NH₃)** - While not a "gas" in the same sense as N₂ or N₂O, ammonia can be released into the environment as a gaseous byproduct in some cases, especially in high concentrations.
4. **Hydrogen (H₂)** - Some nitrogen-fixing bacteria can release hydrogen gas as a byproduct during the fixation process or associated metabolic activities.
The main product of nitrogen fixation is ammonia, but these other gases can also be present depending on the specific microorganisms and environmental conditions involved in the nitrogen-fixing process.
