Blue-green cyanobacteria
- In the ocean, blue-green cyanobacteria are the most abundant type of bacteria to fix nitrogen. Collectively, these organisms are called diazotrophs, and account for close to 90% of natural nitrogen fixation.

May 15, 2020 · N 2 fixation was also generally thought to be largely attributable to only two types of cyanobacteria—the free-living filamentous colony-forming Trichodesmium and the symbionts of diatoms, Richelia —both of which were found primarily in tropical and subtropical surface waters.

The process is called “nitrogen fixation.” On land, bacteria in soil do the heavy lifting by converting N 2 into organic nutrients like ammonium (NH 4 +) and nitrate (NO 3 –) that are usable by plants. In the ocean, blue-green cyanobacteria are the most abundant type of bacteria to fix nitrogen.
Several obligately anaerobic bacteria fix nitrogen including many (but not all) Clostridium spp. Some archaea such as Methanosarcina acetivorans also fix nitrogen, [42] and several other methanogenic taxa , are significant contributors to nitrogen fixation in oxygen-deficient soils.
