Nitrifying bacteria were detected in 64% of samples collected from five chloraminated water supplies in South Australia and in 20.7% of samples that contained more than 5.0 mg of monochloramine per liter. Laboratory experiments confirmed that nitrifying bacteria are relatively resistant to the disinfectant. Increased numbers of the bacteria were associated with accelerated decays of monochloramine within distribution systems. The combination of increased concentrations of oxidized nitrogen with decreased total chlorine residuals can be used as a rapid indicator of bacterial nitrification.
在从南澳大利亚五个加氯胺供水系统采集的样本中，64%检测到了硝化细菌，在每升含超过5.0毫克一氯胺的样本中，20.7%检测到了硝化细菌。实验室实验证实，硝化细菌对消毒剂具有相对抗性。细菌数量增加与配水系统中一氯胺的加速衰减有关。氧化态氮浓度增加与总氯残留量减少相结合，可作为细菌硝化作用的快速指标。
