Nitrifier Gene Abundance and Diversity in Sediments Impacted by Acid Mine Drainage
Frontiers in Microbiology, 2017 Extremely acidic and metal-rich acid mine drainage (AMD) waters can have severe toxicological effects on aquatic ecosystems. AMD has been shown to completely halt nitrification, which plays an important role in transferring nitrogen to higher organisms ...

Nitric oxide scavengers differentially inhibit ammonia oxidation in ammonia-oxidizing archaea and bacteria [PDF]
FEMS Microbiology Letters, 2016 Differential inhibitors are important for measuring the relative contributions of microbial groups, such as ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA), to biogeochemical processes in environmental samples. In particular, 2-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl 3-oxide (PTIO) represents a nitric oxide scavenger used for ...

Low yield and abiotic origin of N2O formed by the complete nitrifier Nitrospira inopinata
Nature Communications, 2019 Ammonia-oxidizing bacteria and archaea are major producers of the gases nitrous oxide and nitric oxide. Here, Kits et al. show that a complete ammonia-oxidizing (comammox) bacterium emits nitrous oxide at levels that are comparable to those produced by ...

Responses of Ammonia-Oxidizing Microorganisms to Intercropping Systems in Different Seasons
Agriculture, 2021 Intercropping plays an essential role in agricultural production, impacting the soil’s physical and chemical properties and microbial communities. However, the responses of ammonia-oxidizing microorganisms in the continuous-cropping soil to different ...
