Novel anammox bacteria and nitrogen loss from Lake Superior.

ABSTRACT: Anaerobic ammonium oxidizing (anammox) bacteria own a central position in the global N-cycle, as they have the ability to oxidize NH₄⁺ to N₂ under anoxic conditions using NO₂^-. They are responsible for up to 50% of all N₂ released from marine ecosystems into the atmosphere and are thus indispensible for balancing the activity of N-fixing bacteria and completing the marine N-cycle. The contribution, diversity, and impact of anammox bacteria in freshwater ecosystems, however, is largely unknown, confounding assessments of their role in the global N-cycle. Here we report the activity and diversity of anammox bacteria in the world's largest freshwater lake-Lake Superior. We found that anammox performed by previously undiscovered
