DOI: 10.1007/s00374-019-01352-z
Abstract: In this study, we show that composition shifts of ammonia oxidizer communities imposed by a 22-year field fertilization regime could be well retained in both fresh and air-dried soils. The abundance and composition of ammonia-oxidizing… read more here.

DOI: 10.1016/j.apsoil.2020.103729
Abstract: Abstract Ammonia oxidation, the rate-limiting step of autotrophic nitrification, is carried out by ammonia-oxidizing archaea (AOA) and bacteria (AOB) that differ in their physiology and metabolic pathways. However, there has been little field investigations on… read more here.

DOI: 10.3389/fmicb.2022.1062703
Abstract: Introduction The large-scale development of animal husbandry and industrialization lead to more and more serious co-contamination from heavy metals and antibiotics in soils. Ecotoxic effects of residues from antibiotics and heavy metals are of increasing… read more here.
