摘要 气相色谱和基因表达分析表明，贝壳生物膜中的硝化作用和动物肠道中的反硝化作用是 Dreissena polymorpha (Bivalvia) 排放 N2O 的原因。贻贝的铵排泄足以维持 N2O 的产生，因此有可能将无脊椎动物 N2O 的产生与环境 N 浓度分开。
ABSTRACT Nitrification in shell biofilms and denitrification in the gut of the animal accounted for N2O emission by Dreissena polymorpha (Bivalvia), as shown by gas chromatography and gene expression analysis. The mussel's ammonium excretion was sufficient to sustain N2O production and thus potentially uncouples invertebrate N2O production from environmental N concentrations.
