We investigate the hidden diversity and distributions of nitrogenases and diazotrophs, and compile evidence for their in situ activities within deep-sea cold seep sediments.
Soil diazotrophs are ubiquitous bacteria and archaea responsible for converting atmospheric nitrogen into plant-available ammonium. This process, if properly harnessed, can ameliorate excessive fertil
The nitrogenase enzyme, which catalyzes the reduction of N2 gas to NH4+, occurs as three separate isoenzymes that use Mo, Fe-only, or V. The majority of global nitrogen fixation is attributed to the m
