Autecological Study of the Chemoautotroph Nitrobacter by Immunofluorescence [PDF]

Applied Microbiology, 1974
Fluorescent antibodies (FA) prepared for Nitrobacter agilis and N. winogradskyi were highly reactive in homologous staining. Low-level cross-reactions between the two species were removed by adsorption.

Detection and counting of Nitrobacter populations in soil by PCR [PDF]

Applied and Environmental Microbiology, 1995
Although the biological conversion of nitrite to nitrate is a well-known process, studies of Nitrobacter populations are hindered by their physiological characteristics. This report describes a new method for detecting and counting Nitrobacter populations in situ with the PCR.

RNA extraction protocol from low-biomass bacterial Nitrosomonas europaea and Nitrobacter winogradskyi cultures for whole transcriptome studies

STAR Protocols, 2023
Summary: RNA-sequencing for whole transcriptome analysis requires high-quality RNA in adequate amounts, which can be difficult to generate with low-biomass-producing bacteria where sample volume is limited.

Innovative Field Applications of Probiotics, Prebiotics, and Medicinal Plant Products for Disease Control in Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Disease outbreaks and the associated reliance on antibiotics pose major constraints to the sustainability of modern aquaculture. As regulatory pressures increase and consumer demand shifts toward residue‐free production, diverse biological interventions are gaining prominence as viable alternatives to chemotherapeutics.

Distribution of Nitrobacter and Nitrospira Communities in an Aerobic Activated Sludge Bioreactor and their Contributions to Nitrite Oxidation [PDF]

, 2020
An analysis of nitrite-oxidizing bacteria in the activated sludge process of a full-scale partially nitrifying wastewater treatment plant revealed Nitrospira and Nitrobacter averaged 10 13 cells·L -1 and 10 12 cells·L -1 , respectively.

Biochar‐Based Urea Enhances Yield and Quality of Lady's Finger (Abelmoschus esculentus L.): A Pathway Towards Sustainable Nitrogen Management

GCB Bioenergy, Volume 18, Issue 7, July 2026.
Biochar‐coated urea markedly improved growth, yield, nitrogen‐use efficiency, and nutritional quality of lady's finger compared with conventional urea. This biochar‐based slow‐release fertilizer offers a sustainable pathway to reduce nitrogen losses, enhance productivity, and improve economic returns while mitigating environmental degradation ...

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.

Coexistence of nitrifying, anammox and denitrifying bacteria in a sequencing batch reactor

Frontiers in Microbiology, 2014
Elevated nitrogen removal efficiencies from ammonium-rich wastewaters have been demonstrated by several applications, that combine nitritation and anammox processes. Denitrification will occur simultaneously when organic carbon is also present.

Improving Essential Oil, Pigments, and Mineral Accumulation in Basil Through Integrated Silicon and Nano‐Fertilizer Treatments in Aquaponics

Food Science &Nutrition, Volume 14, Issue 6, June 2026.
Combined Si and nano‐fertilizers enhanced basil growth and biomass. Essential oil, pigments, and mineral content significantly increased. Integrated nutrition improved yield and quality in aquaponic systems. ABSTRACT Innovative agricultural production systems and effective nutrient management approaches are essential to meet an escalating global demand
