Ubiquity and Diversity of Complete Ammonia Oxidizers (Comammox) [PDF]
The discovery of complete ammonia oxidizers (comammox), which oxidize ammonia to nitrate via nitrite, refutes the century-old paradigm that nitrification requires the activity of two types of microbes and redefines a key process in the biogeochemical nitrogen cycle.

Complete nitrification: insights into the ecophysiology of comammox Nitrospira [PDF]
Nitrification, the oxidation of ammonia via nitrite to nitrate, has been considered to be a stepwise process mediated by two distinct functional groups of microorganisms. The identification of complete nitrifying Nitrospira challenged not only the paradigm of labor division in nitrification, it also raises fundamental questions regarding the ...

Evaluation of four primer sets for analysis of comammox communities in black soils
Comammox, as a newly discovered ammonia oxidizer, urgently needs highly efficient and specific primers to detect its community structure and diversity. In this study, the performance of widely used primer set Ntsp-amoA 162F/359R and newly designed primer

Community assembly of comammox Nitrospira in coastal wetlands across southeastern China. [PDF]
ABSTRACT Complete ammonia oxidizers (comammox Nitrospira ) are ubiquitous in coastal wetland sediments and play an important role in nitrification. Our study examined the impact of habitat modifications on comammox Nitrospira communities in coastal wetland sediments across tropical ...

Hot spring distribution and survival mechanisms of thermophilic comammox Nitrospira
Abstract The recent discovery of Nitrospira species capable of complete ammonia oxidation (comammox) in non-marine natural and engineered ecosystems under mesothermal conditions has changed our understanding of microbial nitrification.
