Making Dinitrogen

Environment: Pathway involves microbial oxidation of ammonia via nitric oxide and hydrazine
Department: Science & Technology
Keywords: anammox, hydrazine, nitrogen cycle, wastewater treatment

The mechanics of a key biogeochemical reaction that affects atmospheric chemistry have been identified by an international research group. The research shows how one of two major routes for putting dinitrogen into the atmosphere happens via a microbiological process known as anammox, for anaerobic ammonium oxidation.

In the new work, Boran Kartal of the Netherlands’ Radboud University Nijmegen and colleagues demonstrate that microbes turn ammonium into dinitrogen anaerobically . . .
