Abstract

Dinitrogen-fixing (N₂-fixing) microorganisms, termed "diazotrophs" include members of the bacteria and archaea, and are functionally important microbes that supply nitrogen (N) to the biosphere by converting N₂ to ammonia (NH₃). In the open sea, this process is an important mode of introducing fixed N to the marine food web and is inextricably linked to the cycling of other bioessential nutrients. Here, we review the genetic and metabolic basis for oceanic diazotroph diversity and discuss how this diversity impacts biogeochemical cycles and conclude with how changes to marine ecosystems might influence the future role of diazotophs in ocean ecology and biogeochemistry.
