Nitrification in shell biofilms and denitrification in the gut of the animal accounted for N(2)O emission by Dreissena polymorpha (Bivalvia), as shown by gas chromatography and gene expression analysis. The mussel's ammonium excretion was sufficient to sustain N(2)O production and thus potentially uncouples invertebrate N(2)O production from environmental N concentrations.
贝类生物膜的硝化作用和动物肠道的反硝化作用导致多形盘绕蚌(双壳类)排放 N2O,这一点通过气相色谱和基因表达分析得到证实。贻贝的氨排泄足以维持 N2O 的产生,从而使无脊椎动物 N2O 的产生与环境 N 浓度脱钩。
