Application of the modern microbial techniques changed the paradigm about the microorganisms performing nitrification. Numerous investigations recognized representatives of the genus Nitrospira as a key and predominant nitrite-oxidizing bacteria in biological nutrient removal systems, especially under low dissolved oxygen and substrate conditions. The recent discovery of Nitrospira capable of performing complete ammonia oxidation (comammox) raised a fundamental question about the actual role of Nitrospira in both nitrification steps. This review summarizes the current knowledge about morphological, physiological and genetic characteristics of the canonical and comammox Nitrospira. Potential implications of comammox for the functional aspects of nitrogen removal have been highlighted. The complex meta-analysis of literature data was applied to identify specific individual variables and their combined interactions on the Nitrospira abundance. In addition to dissolved oxygen and influent nitrogen concentrations, temperature and pH may play an important role in enhancing or suppressing the Nitrospira activity.

硝化螺菌在脱氮系统中的发生和作用。

现代微生物技术的应用改变了进行硝化作用的微生物的范式。大量研究确认硝化螺菌属的代表是生物营养去除系统中的关键且占主导地位的亚硝酸盐氧化细菌，尤其是在低溶解氧和底物条件下。能够进行完全氨氧化（comammox）的硝化螺菌的最新发现提出了一个基本问题，即硝化螺菌在两个硝化步骤中的实际作用。这篇综述总结了有关规范和昏迷硝化螺菌的形态，生理和遗传特征的最新知识。强调了comammox对脱氮功能方面的潜在影响。对文献数据进行复杂的荟萃分析，以鉴定特定个体变量及其在硝化螺菌丰度上的组合相互作用。除了溶解氧和进水氮浓度外，温度和pH值可能在增强或抑制硝化螺菌活性中起重要作用。
