Investigating microbial and environmental drivers of nitrification in alkaline forest soil. [PDF]
ISME CommunAmmonia oxidation is a key step in the biogeochemical cycling of nitrogen, and soils are important ecosystems for nitrogen flux globally. Approximately 25% of the world’s soils are alkaline.

Sustained nitrogen loss in a symbiotic association of ComammoxNitrospiraand Anammox bacteria [PDF]
Water Research, 2020 ABSTRACTThe discovery of complete aerobic and anaerobic ammonia-oxidizing bacteria (Comammox and Anammox) significantly altered our understanding of the global nitrogen cycle. A high affinity for ammonia (Km(app),NH3≈ 63nM) and oxygen place the first described isolate, ComammoxNitrospira inopinatain the same trophic category as organisms such as some ...

Diversity and abundance of comammox bacteria in the sediments of an urban lake [PDF]
Journal of Applied Microbiology, 2020 Although comammox have been discovered in a variety of ecosystems, there are few studies in urban lakes. This paper attempted to confirm whether this ammonia-oxidizing microbe exists in urban lakes and to determine the factors influencing its existence.This study investigated the diversity and abundance of comammox bacteria in sediments of a typical ...

Expanding perspectives of soil nitrification to include ammonia‐oxidizing archaea and comammox bacteria [PDF]
Soil Science Society of America Journal, 2020 Abstract Catalyzed by multiple groups of phylogenetically distinct microorganisms, soil nitrification impacts ground water quality, greenhouse gas emissions, and agricultural practices. This review explores known microbial players involved in nitrification, encompassing aspects of biogeography, phylogenetic ...

Journal of Hazardous Materials, 2023 Benzimidazole fungicides are frequently detected in aquatic environments and pose a serious health risk. Here, we investigated the metabolic capacity of the recently discovered complete ammonia-oxidizing (comammox) Nitrospira inopinata and kreftii to transform a representative set of benzimidazole fungicides (i.e., benzimidazole, albendazole ...
