Microbial community response reveals underlying mechanism of industrial-scale manganese sand biofilters used for the simultaneous removal of iron, manganese and ammonia from groundwater

AMB Express, 2018
Most studies have employed aeration–biofiltration process for the simultaneous removal of iron, manganese and ammonia in groundwater. However, what’s inside the “black box”, i.e., the potential contribution of functional microorganisms behavior and ...

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.

Comparative analysis of ammonia monooxygenase (amoA) genes in the water column and sediment-water interface of two lakes and the Baltic Sea [PDF]

, 2008
The functional gene amoA was used to compare the diversity of ammonia-oxidizing bacteria (AOB) in the water column and sediment-water interface of the two freshwater lakes Plusssee and Schöhsee and the Baltic Sea.

Acidification Stimulates N2O Production by Oceanic Nitrifying Bacteria

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Recent studies have shown changes in the production rates of nitrous oxide (N2O) in aerobic seawater in response to ocean acidification (OA). Understanding how N2O production responds to OA is crucial because N2O is a strong greenhouse gas and stratospheric ozone‐depleting substance emitted from the ocean.

Physiological function and catalytic versatility of bacterial multihaem cytochromescinvolved in nitrogen and sulfur cycling [PDF]

, 2011
Bacterial MCCs (multihaem cytochromes c) represent widespread respiratory electron-transfer proteins. In addition, some of them convert substrates such as nitrite, hydroxylamine, nitric oxide, hydrazine, sulfite, thiosulfate or hydrogen peroxide. In many

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.

A mathematical model of bacteria capable of complete oxidation of ammonium predicts improved nitrogen removal and reduced production of nitrous oxide [PDF]

, 2017
The removal of excess nutrients from water ecosystems requires oxidation of toxic ammonium by two types of bacteria; one oxidizes ammonium to nitrite and the other oxidizes nitrite to nitrate.

Liquid Chromatography—Mass Spectrometry-Based Proteomics of Nitrosomonas [PDF]

, 2011
During the last century, the research on aerobic ammonium-oxidizing bacteria (AOB) lead to many exciting physiological and biochemical discoveries. Nevertheless the molecular biology of AOB is not well understood. The availability of the genome sequences of several Nitrosomonas species opened up new possiblities to use state of the art transcriptomic ...
