Achieving short-cut nitrification and denitrification in modified intermittently aerated constructed wetland [PDF]

open access: yes, 2017
This study aim to enhance nitrogen removal performance via shifting nitrogen removal pathway from nitrate to nitrite pathway. It was demonstrated that nitrite pathway was successfully and stably achieved in CWs by using modified intermittent aeration ...

Nitrification-denitrification in WSP: a mechanism for permanent nitrogen removal in maturation ponds [PDF]

open access: yes, 2009
A pilot-scale primary maturation pond was spiked with 15N-labelled ammonia (15NH4Cl) and 15N labelled nitrite (Na15NO2), in order to improve current understanding of the dynamics of inorganic nitrogen transformations and removal in WSP systems.

Probiotic Bacillus subtilis enhances production efficiency in biofloc‐raised Cherax quadricarinatus via microbiome remodeling and host antioxidant capacity upregulation

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.
Abstract Biofloc technology (BFT) presents a sustainable approach to aquaculture intensification by recycling nutrients and reducing water exchange. However, probiotic supplementation for optimization in emerging species such as redclaw crayfish (Cherax quadricarinatus) remains unexplored. This study investigated how Bacillus subtilis (B.

Biotehnološki značajna bakterija Nitrospira u geotermalnim izvorima Republike Hrvatske [PDF]

open access: yes, 2020
Mikrobne zajednice geotermalnih izvora izvrstan su primjer mogućnosti odvijanja života u ekstremnim uvjetima. Poznavanje ekstremofilnih zajednica poput termofilnih bakterija ključno je za daljnje razumijevanje metabolizma, strukture i međusobnih odnosa unutar ekosustava.

Network of Nitrifying Bacteria in Aquarium Biofilters: An Unfaltering Cooperation Between Comammox Nitrospira and Ammonia-Oxidizing Archaea

open access: yesWater
Nitrification plays a crucial role in aquatic ecosystems and in the biofilters used in fish farms. Despite their importance, the role of canonical nitrifiers, comammox bacteria, and archaea has not yet been sufficiently investigated.

Enrichment and physiological characterization of a novel comammox Nitrospira indicates ammonium inhibition of complete nitrification

open access: yesThe ISME Journal, 2020
The recent discovery of bacteria within the genus Nitrospira capable of complete ammonia oxidation (comammox) demonstrated that the sequential oxidation of ammonia to nitrate via nitrite can also be performed within a single bacterial cell.

Predicting taxonomic and functional structure of microbial communities in acid mine drainage. [PDF]

open access: yes, 2016
Predicting the dynamics of community composition and functional attributes responding to environmental changes is an essential goal in community ecology but remains a major challenge, particularly in microbial ecology.

Hydrological and microbial dynamics in an Arctic wastewater infiltration system

open access: yesVadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract Passive wastewater treatment systems are widely used in the Arctic, but studies addressing the vadose zone dynamics that influence the operation and performance of subsurface or soil‐based infiltration systems, such as rapid infiltration basins, are rare.
