Global nitrogen cycle: critical enzymes, organisms, and processes for nitrogen budgets and dynamics
Nitrogen (N) is used in many of life's fundamental biomolecules, and it is also a participant in
environmental redox chemistry. Biogeochemical processes control the amount and form of N …

Microbial nitrogen cycling in estuaries: from genes to ecosystem processes
J Damashek, CA Francis - Estuaries and Coasts, 2018 - Springer
Nitrogen (N) is one of the primary nutrients required to build biomass and is therefore in high
demand in aquatic ecosystems. Estuaries, however, are frequently inundated with high …
