Enrichment of Comammox and Nitrite-Oxidizing Nitrospira From Acidic Soils [PDF]
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 ...
