Exploring bacterial communities in aquaponic systems [PDF]
, 2019 Aquaponics is a production system based on the dynamic equilibrium between fish, plants, and microorganisms. In order to better understand the role of microorganisms in this tripartite relationship, we studied the bacterial communities hosted in eight ...

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 ...

Cyclic Conversions in the Nitrogen Cycle
Frontiers in Microbiology, 2021 The cyclic nature of specific conversions in the nitrogen cycle imposes strict limitations to the conversions observed in nature and explains for example why anaerobic ammonium oxidation (anammox) bacteria can only use nitrite – and not nitrate – as ...

Existence and distribution of novel phylotypes of Nitrospira in water columnsof the South China Sea
iScience, 2022 Summary: In the biological nitrogen cycle, nitrite oxidation is performed by nitrite oxidation bacteria, of which Nitrospira is widespread and diverse. Communities of Nitrospira were collected at 25–1500 m depths in the South China Sea.

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 ...

Niche differentiation and evolution of comammox Nitrospira through a comparative genomics analysis [PDF]
, 2017 Nitrification, the biological oxidation of ammonium to nitrate, is a fundamental process in the nitrogen cycle and plays an important role in natural and engineered systems. Throughout the last century, nitrification was assumed to be a two-step process executed by two different functional groups, ammonia oxidizing prokaryotes (AOP) and nitrite ...

Comparative genomics sheds light on niche differentiation and the evolutionary history of comammox Nitrospira. [PDF]
ISME J, 2018 Abstract The description of comammox Nitrospira spp., performing complete ammonia-to-nitrate oxidation, and their co-occurrence with canonical β-proteobacterial ammonia oxidizing bacteria (β-AOB) in the environment, calls into question the metabolic potential of comammox Nitrospira and the evolutionary history of their ammonia ...
