Nitrogen Fixation. In their Communication (e202307101), Guillermo C. Bazan et al. developed a new strategy to enable light-driven nitrogen fixation in non-photosynthetic bacteria by integrating the novel conjugated oligoelectrolyte into Azotobacter vinelandii.
Nitrogen fixation (C(2)H(2) reduction) by algae in flooded soil was limited by interactions within the algal community. Nitrogen fixation by either indigenous algae or Tolypothrix tenuis was reduced severalfold by a dense suspension of the green alga Nephrocytium sp. Similarly, interactions between the nitrogen-fixing alga (cyanobacterium) Aulosira 68 and natural densities of indigenous algae l...
Leptolyngbya boryana (Plectonema boryanum) is a diazotrophic cyanobacterium lacking heterocysts. How nitrogen fixation is regulated in filamentous nonheterocystous cyanobacteria remains unclear. Here we describe a large 50-kb nitrogen fixation (nif) gene cluster in L. boryana containing 50 genes. This gene cluster contains 14 nif genes (nifBSUHDKVZT and nifPENXW), two genes encoding transcripti...
