WebJan 1, 2024 · 1. Introduction. Nitrogen fixation is the process of converting molecular nitrogen (N 2, which makes up 78% of the atmosphere) into ammonia (NH 3, which is used by many organisms as a nitrogen source).With a few exceptions, only a limited number of prokaryotes are capable of nitrogen fixation, and they are distributed in a mosaic … WebSteps. Ammonia production and nitrification are the two main processes involved in non-symbiotic nitrogen fixation. By the reduction of nitrogen in the atmosphere, ammonia is created. Nitrosomonas, Nitrosococcus, and Nitrosospira turn ammonia into nitrite. When ammonia is converted to nitrite and nitrate, nitrifying bacteria play a major role. WebSymbiotic specificity is not confined to the early recognition stages; incompatible host-strain combinations can lead to formation of nodules that are defective in nitrogen fixation (Fix-).
