Microbial activities drive the global nitrogen cycle, and in the past few years, our understanding of nitrogen cycling processes and the micro-organisms that mediate them has changed dramatically.

Understanding the bacteria’s role in the nitrogen cycle is critical to unraveling the impact of human activity on the planet’s delicate nitrogen balance. In an attempt to better understand which bugs ...

A study reveals how bacteria present in marine particles maintain the oceanic nitrogen cycle, providing ecological stability ...

The molecular mechanism of anaerobic ammonium oxidation has been unraveled. The anaerobic oxidation of ammonia (anammox) is an important pathway in the nitrogen cycle that was only discovered in ...

The symbiosis between some plant species and nitrogen-fixing nodule bacteria is one of the most relevant cooperative relationships in the world. It shapes our global vegetation and, not least, the ...

The study also shows that the activity of these bacteria accounts for about 10% of the overall N 2 fixation in the global ...

Nitrogen-fixing bacteria need oxygen, as they are aerobic. Decomposition Bacteria/fungi break down protein found in dead plants and animals, urine and faeces close faeces Waste matter from the ...

Everything students need to know about the nitrogen cycle for CCEA GCSE Biology. ... Nitrogen-fixing bacteria need oxygen, as they are aerobic. Decomposition.

Nitrogen fixation by bacteria completes the nitrogen cycle, providing nitrogen to plants that are then consumed by other life, the nitrogen eventually being returned to the environment.
