The fixation of nitrogen is the most fundamental biochemical process after photosynthesis. It is the process whereby atmospheric nitrogen is reduced to ammonia. Nitrogen fixation can be carried out by blue-green algae, some yeasts, and especially bacteria. The reduction of nitrogen...

Figure 15.23. The most important biologically mediated nitrogen conversion processes (compare Table 15.9). Natural N fixation occurs through certain blue-green algae and through certain bacteria, which live in symbiosis with plants (leguminosae). Microorganisms mediate, under aerobic conditions, the nitrification of NH4 (and NH3) to NOa and NO ". At low pe (pe < 6 at pH = 7) the reduction to is possible. Organic compounds can cause the reduction of NO to N2 (denitrification) (see reaction 3 in Table 15.9). NO and NjO may occur as intermediates, both in nitrification and denitrification (reactions 9 and 10 in Table 15.9).
