Nitrospira -Like Bacteria Associated with Nitrite Oxidation in Freshwater Aquaria [PDF]

Applied and Environmental Microbiology, 1998
ABSTRACT Oxidation of nitrite to nitrate in aquaria is typically attributed to bacteria belonging to the genus Nitrobacter which are members of the α subdivision of the class Proteobacteria . In order to identify bacteria responsible for nitrite oxidation in aquaria, clone libraries

A Systematic Review of Biofloc Technology and Periphyton in Giant Freshwater Prawn (Macrobrachium rosenbergii) Aquaculture

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Biofloc technology and periphyton‐based systems enhance the sustainable production of giant freshwater prawn (Macrobrachium rosenbergii). A PRISMA‐guided review (2005 – 2024) shows that BFT improves survival (75 – 78 %) and feed efficiency, while periphyton supports natural productivity in grow‐out.

Cultivation of a novel cold-adapted nitrite oxidizing betaproteobacterium from the Siberian Arctic [PDF]

, 2007
Permafrost-affected soils of the Siberian Arctic were investigated with regard to identification of nitrite oxidizing bacteria active at low temperature.

Hydrological and microbial dynamics in an Arctic wastewater infiltration system

Vadose 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.

Long‐term microbial community dynamics at two full‐scale biotrickling filters treating pig house exhaust air [PDF]

, 2019
In this study, the microbial community structure of two full-scale biotrickling filters treating exhaust air from a pig housing facility were evaluated using 16S metabarcoding.

Hydrazine Synthase From Anammox Is Inhibited by Linear and Aromatic Alkynes

Environmental Microbiology, Volume 28, Issue 3, March 2026.
Linear and aromatic alkynes inhibit anammox in culture and in wetlands. The inhibition by alkynes is specific to the hydrazine synthase, a key enzyme in the anammox pathway. ABSTRACT N2O emissions by nitrifiers are often estimated using selective inhibitors, such as 1‐alkynes.

Unraveling the important role of comammox Nitrospira to nitrification in the coastal aquaculture system

Frontiers in Microbiology
Increasing nitrogen (N) input to coastal ecosystems poses a serious environmental threat. It is important to understand the responses and feedback of N removal microbial communities, particularly nitrifiers including the newly recognized complete ammonia-

Heterologous plastoquinone production using a newly identified O2‐dependent cyanobacterial hydroxylase

The FEBS Journal, Volume 293, Issue 6, Page 1708-1726, March 2026.
In this study, we confirm that PlqH is the hydroxylase operating in plastoquinone biosynthesis in photosynthetic cyanobacteria (Cyanobacteriia). Our phylogenetic analyses demonstrate that cyanobacterial PlqH homologues originated from hydroxylases involved in ubiquinone biosynthesis in bacteria. Plastoquinone production in Escherichia coli was achieved

Ammonia-oxidizing archaea and complete ammonia-oxidizing Nitrospira in water treatment systems

Water Research X, 2022
Nitrification, the oxidation of ammonia to nitrate via nitrite, is important for many engineered water treatment systems. The sequential steps of this respiratory process are carried out by distinct microbial guilds, including ammonia-oxidizing bacteria (

Quantifying community dynamics of nitrifiers in functionally stable reactors [PDF]

, 2008
A sequential batch reactor (SBR) and a membrane bioreactor (MBR) were inoculated with the same sludge from a municipal wastewater treatment plant, supplemented with ammonium, and operated in parallel for 84 days.
