WebJun 18, 2024 · Biotic nitrogen fixation by free-living microorganisms. Nitrogen-fixing microorganisms that live in the soil in a free (asymbiotic) form are basically archaebacteria and bacteria. There are several types of bacteria and cyanobacteria that can convert atmospheric nitrogen, N 2, in ammonia, NH 3. According to the chemical reaction: WebBacteria play a key role in the nitrogen cycle. Nitrogen enters the living world by way of bacteria and other single-celled prokaryotes, which convert atmospheric nitrogen— \text N_2 N2 —into biologically usable forms in a process called nitrogen fixation.
