Fixation microbiology
WebRecently great progress has been made in this research area, and dozens of CO 2 -derived fuels and chemicals have been reported to be synthesized by autotrophic microbes. This is accompanied by investigations into natural CO 2 -fixation pathways and the rapid development of new technologies in synthetic biology. WebJun 10, 2024 · Nitrogen fixation is a uniquely procaryotic process apart from a limited amount of nitrogen fixation that occurs during lightning strikes, all organic nitrogen is of procaryotic origin. Nitrogen fixation can be carried out under oxic and anoxic condition. Flows that occur predominantly under oxic conditions are noted with open arrows.
