摘要
直接以氨为电子供体的反硝化反应是一种新的生物反应.作者对能进行这种生物反应的厌氧氨氧化菌混培物的基质转化特性作了研究.试验发现,除已被证实的硝酸盐外,亚硝酸盐和N2O也能作为厌氧氨氧化的电子受体;还发现,在厌氧氨氧化中可产生中间产物羟胺和联氨,彼此可相互转化.此外。
Denitrification with ammonium as direct electron donor is a new biological reaction. The substrate conversion characteristics of the mixed microbial culture that carried out the bioreaction were studied here. The results showed that in addition to the known electron acceptor nitrate, nitrite and nitrous oxide were also able to serve as electron acceptor in the bioreaction. During anaerobic ammonium oxidation by the mixed microbial culture, hydroxylamine and hydrazine were detected as intermediates and they were found interconvertible. The possible pathway of the bioreaction was discussed.
