Collaborative metabolisms of urea and cyanate degradation in marine anammox bacterial culture.

ABSTRACT: Anammox process greatly contributes to nitrogen loss occurring in oceanic oxygen minimum zones (OMZs), where the availability of NH₄⁺ is scarce as compared with NO₂^-. Remineralization of organic nitrogen compounds including urea and cyanate (OCN^-) into NH₄⁺ has been believed as an NH₄⁺ source of the anammox process in oxygen minimum zones. However, urea- or OCN^-- dependent anammox has not been well examined due to the lack of marine anammox bacterial culture. In the present study, urea and OCN^- degradation in a marine anammox bacterial consortium were investigated based on ¹⁵N-tracer experiments and metagenomic analysis. Although a marine anammox bacterium,
