Conclusion – Difference between Azotobacter and Azospirillum
Azotobacter and Azospirillum are two distinct genera of diazotrophs found in different ecological niches. Azotobacter spp. function as free-living nitrogen fixers. Azospirillum spp., on the other hand, act as associative nitrogen fixers promoting plant growth through hormone secretion. Both of them are valuable for soil fertility and biofertilizer production in the agriculture industry.
Difference between Azotobacter and Azospirillum
The main difference between Azotobacter and Azospirillum lies in the way these nitrogen fixers are found in nature. The Azotobacter species are non-symbiotic nitrogen-fixing bacteria, whereas the Azospirillum species are associative rhizobacteria that fix nitrogen. Azotobacter are aerobic, free-living species. They are widely distributed in soils and waters. On the contrary, Azospirillum spp. are microaerophilic and often found in a beneficial association with plants.
They are present either in the rhizospheres or the roots of important crop plants. Both of them are diazotrophs, meaning they are capable of biological nitrogen fixation (BNF). In this article, we will look into the differences between Azotobacter and Azospirillum in detail.
