Nitrification in shell biofilms and denitrification in the gut of the animal accounted for N2 O emission byDreissena polymorpha (Bivalvia), as shown by gas chromatography and gene expression analysis. The mussel's ammonium excretion was sufficient to sustain N2 O production and thus potentially uncouples invertebrate N2 O production from environmental N concentrations.
