延伸阅读
反硝化作用 硝酸盐在某些微生物的作用下还原为气态氮的过程。多发生于沼泽、湖泊和渍水土壤等缺氧环境中。其反应过程可简示为：2HNO3─→2HNO2─→2HNO─→N2。参与作用过程的微生物主要是反硝化细菌。作用的强度主要取决于土壤中的氧浓度和土壤pH。所有的反硝化细菌都是兼气性细菌，反硝化作用只有在土壤中的氧浓度较低时才能进行。当氧浓度减至5％以下时,反硝化作用明显增强。在过湿的环境中或在通气土壤的局部嫌气区（如根际），都能测得较明显的反硝化作用。反硝化作用的最适pH为7.0～8.2。当pH低至5.2～5.8或高达8.2～9.0时，反硝化作用的强度都会显著减弱。 在自然界，除上述通常由反硝化细菌引起的反硝化作用外，还常由以下途径使介质中的硝酸盐还原为气态氮:①某些微生物通过对硫的氧化或某些含硫化合物,而使硝酸盐还原:2S＋6KNO3＋2CaCO3─→2K2SO4＋2CaSO4＋2CO2＋3N2。 ②通过纯化学过程使硝酸盐还原为气态氮。但这一过程与真正的反硝化作用不同。 由于反硝化作用导致土壤氮或施入土壤中的氮肥中氮的损失，因而对植物生长不利。农业生产上常需采取措施改善土壤通气状况和调节土壤酸度，防止和减缓反硝化作用的发生。
