WebDec 16, 2024 · The metabolic reactions involving nitrogen that bacteria perform include: nitrogen fixation (N2 → NH3), nitrification (NH3 → NO3 - or NO2 -), and denitrification (NO3 - or NO2 - → NO, N2O, and N2), all of which make up the nitrogen cycle. Each of these reactions is carried out by a unique set of microorganisms with a distinct ecological niche. WebJun 15, 2024 · The fixation of atmospheric N2 to NH3 is an essential process for sustaining life. One grand challenge is to develop efficient catalysts to photofix N2 under ambient conditions.
