16S and amoA genes amplicons from nitrifying soil microorganisms
Sequenced 16S and amoA genes of ammonia oxidizing achaea, bacteria and comammox from SIP fractionated DNA extracted from agricultural soils incubated with different N sources (no nitrogen, ammonium sulfate, grass litter and legume litter) incubated with 13C- and 12CO2. The aim was to identify different ammonia oxidizers active in tropical agricultural soils and identify niche preferences (organic vs inorganic).
