The human acceleration of the nitrogen cycle did not occur in isolation, as humans have altered the cycles of many other elements as well, most notably those of phosphorus, sulphur and carbon 1.Of ...

The Thaumarchaeota play a key role in the marine nitrogen cycle. They gain energy for growth by converting ammonia, which is the most reduced form of inorganic nitrogen, to a more oxidized form: ...

Understanding the pre-oxygen nitrogen cycle provides a crucial piece of the puzzle in reconstructing the early Earth’s environment and the conditions that led to the evolution of complex life.

This additional part of the nitrogen cycle is called denitrification. Nitrogen fixation, ammonification, nitrification and denitrification, are all parts of the nitrogen cycle that depend on bacteria.
