Long-term Effects of Ni(II), Co(II) and Zn(II) Limitation on the Nitrite-oxidation Activity in Continuous Tests Using PVA Gel Carriers

Journal of Water and Environment Technology
Nitrite-oxidizing bacteria (NOB) can be inhibited by high concentrations of heavy metals; however, trace elements (TE) are critical for their growth and sustained activity.

The Elbe Estuary Microbiome Shifts With Salinity and Discharge and Depends on Fresh Organic Matter and Nutrient Availability

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Microbial diversity within the Elbe Estuary was found to be more strongly governed by seasonal variability, salinity, and discharge than by spatial heterogeneity. Oligohaline regions sustain high diversity, while nutrient and redox conditions drive functional shifts.

Stability and performance of two GSBR operated in alternating anoxic/aerobic or anaerobic/aerobic conditions for nutrient removal [PDF]

, 2012
Two granular sludge sequencing batch reactors (GSBR) with alternating anoxic/aerobic (R1) and anaerobic/aerobic (R2) conditions were operated with a 4-carbon-source synthetic influent. The physical properties of the granular sludge were very good (SVI≈20

Topological data analysis of Escherichia coli O157:H7 and non-O157 survival in soils. [PDF]

, 2014
Shiga toxin-producing E. coli O157:H7 and non-O157 have been implicated in many foodborne illnesses caused by the consumption of contaminated fresh produce.

Core Microbial Taxa Strengthen Root Microbial Network Stability Under Drought Stress

Environmental Microbiology, Volume 28, Issue 5, May 2026.
This study evaluates different drought stresses on microbial diversity and network stability in roots and soils. Microbial diversity shifts across plant growth stages and microbial groups under stress. Enriched core taxa strengthen root microbial network stability under stress.

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 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.

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.

Divergent Responses of Bacterial Communities to Permafrost Degradation and Their Associations With Carbon Across Vertical Profiles

Advanced Science, Volume 13, Issue 23, 23 April 2026.
Bacterial α‐diversity decreases, but stochasticity and community stability increase across the 15 m‐depth vertical profiles and along the degraded gradient within the active layer. The abundance and interaction of core taxa mainly control community stability in the active and permafrost layers, respectively.
