¹⁵N-DNA stable isotope probing reveals niche differentiation of ammonia oxidizers in paddy soils.

ABSTRACT: Chemoautotrophic canonical ammonia oxidizers (ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB)) and complete ammonia oxidizers (comammox Nitrospira) are accountable for ammonia oxidation, which is a fundamental process of nitrification in terrestrial ecosystems. However, the relationship between autotrophic nitrification and the active nitrifying populations during ¹⁵N-urea incubation has not been totally clarified. The ¹⁵N-labeled DNA stable isotope probing (DNA-SIP) technique was utilized in order to study the response from the soil nitrification process and the active nitrifying populations, in both acidic and neutral paddy soils, to the application of urea. The presence of C₂H₂ almost completely inhibited NO₃
