WebNostoc is a cyanobacterium. It has the ability to fix atmospheric nitrogen. It converts nitrogen into ammonia. The heterocysts present in it are specialized for nitrogen fixation. It contains enzyme nitrogenase. Nitrogenase is inactivated by oxygen. Hence, the heterocyst creates a micro anaerobic environment. WebMay 8, 2012 · Nitrogen-fixing bacteria contain an enzyme complex called nitrogenase which catalyses the conversion of nitrogen gas to ammonia. It supplies hydrogen ions as well as energy from ATP. The nitrogenase complex is sensitive to oxygen, becoming inactivated when exposed to it. A method for nitrogen fixation was first described by Henry Cavendish in 1784 using electric arcs reacting nitrogen and oxygen in air. This method was implemented in the Birkeland–Eyde process of 1903. The fixation of nitrogen by lightning is a very similar natural occurring process.
