Biological nitrogen (N) fixation, a key process of N conversion performed by symbiotic or free-living N-fixing organisms, plays an important role in terrestrial N cycling and represents a key driver ...

Nitrogen is vital for all known life. Yet most nitrogen on Earth is in the atmosphere as di-nitrogen gas, which many organisms can’t use. Fortunately, there are microbes that can tap into this ...

Nitrogen is a key nutrient because it fuels the growth of plankton, which forms the basis of the marine food web. Two opposing processes determine the global nitrogen cycle: nitrogen fixation and ...
