Comammox Nitrospira act as key bacteria in weakly acidic soil via potential cobalamin sharing [PDF]
iMetaThe discovery of comammox Nitrospira in low pH environments has reshaped the ammonia oxidation process in acidic settings, providing a plausible explanation for the higher nitrification rates observed in weakly acidic soils.

Community Structure, Assembly and Interactions of Nitrospira Nitrite-Oxidizing Bacteria in Sediments of the Eastern China Marginal Seas [PDF]
MicroorganismsNitrite oxidation, a pivotal process in the nitrogen cycle driven by microorganisms, is primarily carried out by nitrite-oxidizing bacteria (NOB). While extensive studies on Nitrospira have been conducted in terrestrial habitats, knowledge of Nitrospira ...

Enrichment of Comammox and Nitrite-Oxidizing Nitrospira From Acidic Soils
Frontiers in Microbiology, 2020 In agricultural soils fertilized with a high amount of ammonium nitrogen, the pH decreases because of the oxidation of ammonia by nitrifiers. Molecular-based analyses have revealed that members of the genus Nitrospira dominate over other nitrifiers in ...
