On the kinetic and allosteric regulatory properties of the ADP-glucose pyrophosphorylase from Rhodococcus jostii: An approach to evaluate glycogen metabolism in oleaginous bacteria [PDF]

, 2016
Rhodococcus spp. are oleaginous bacteria that accumulate glycogen during exponential growth. Despite the importance of these microorganisms in biotechnology, little is known about the regulation of carbon and energy storage, mainly the relationship ...

Chemolithoorganotrophic Growth of Nitrosomonas europaea on Fructose [PDF]

Journal of Bacteriology, 2003
ABSTRACT The nitrifying bacterium Nitrosomonas europaea can obtain all its carbon for growth from CO 2 and all its energy and reductant for growth from the oxidation of NH 3 and is considered an obligate chemolithoautotroph. Previous studies have shown that

Dynamics and Eco‐Genomics of Baltic Sea Nitrifiers: Seasonality, Niches, Interactions and Genomic Uniqueness

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Nitrifiers in the Baltic Sea show persistent abundance in aphotic waters and late‐fall to winter photic zone increases positively correlated with nutrients and negatively with light and chlorophyll. Through selective enrichment, five novel ammonia‐oxidising archaea genomes were recovered, including the dominant aphotic taxon, which revealed overall ...

Changes in community composition of ammonia-oxidizing betaproteobacteria from stands of Black mangrove (Avicennia germinans) in response to ammonia enrichment and more oxic conditions

Frontiers in Microbiology, 2013
In flooded and non-flooded impounded forests of Black mangrove (Avicennia germinans), the community structure of the ammonia-oxidizing betaproteobacteria (β-AOB) differed among distinct mangrove vegetation cover types and hydrological regimes.

Nitrogen Cycling Under Conifer‐to‐Broadleaf Forest Conversion in Eastern England

European Journal of Soil Science, Volume 77, Issue 1, January–February 2026.
ABSTRACT In the early 20th century, political focus on timber production in Europe led to extensive afforestation and replacement of broadleaves with often non‐native coniferous species. Recent interest in the reverse has risen due to recognition of the wider ecosystem services delivered by forests, such as water quality improvement.

Novel Endogenous Probiotics Enhance Host Intestinal Health, Liver Immune Capacity, Meat Nutritional Composition, and Aquatic Environmental Quality in Pelodiscus sinensis

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Currently, the in‐depth research and practical application of probiotics in the green and healthy breeding of Chinese soft‐shelled turtles (Pelodiscus sinensis) remain limited. This study conducted a 30‐day feeding trial with turtles of an initial weight of 528.95 ± 2.96 g. The aim was to evaluate the effects of three endogenous probiotics—Enterococcus

Characterization of acid-tolerant ammonia-oxidizing Nitrosospira bacteria suggests wide implementation of the acidic nitritation process

Water Research X
Acidic activated sludge process has been recently developed for the suppression of nitrite-oxidizing bacteria, addressing the bottleneck in achieving robust partial nitritation (PN) for low-strength ammonia wastewater treatment.

Determination of the activity of nitrifying bacteria in surface waters by a modified BOD-test. [Translation from: Zentbl.Bakt.Parasitkde 156(1) 414-421, 1972. ] [PDF]

, 1974
A modified method of the Biochemical oxygen demand (BOD)test was applied in order to find out the seasonal changing activity of the nitrifying bacteria in surface waters.

Genera-specific immunofluorescence labeling of ammonia oxidizers with polyclonal antibodies recognizing both subunits of the ammonia monooxygenase [PDF]

, 2004
Polyclonal antibodies that recognize the two subunits AmoA and AmoB of the ammonia monooxygenase (AMO) were applied to identify ammonia-oxidizing bacteria by immunofluorescence (IF) labeling in pure, mixed, and enriched cultures.

The Isolation of Nitrosomonas europaea in Pure Culture [PDF]

Journal of General Microbiology, 1950
SUMMARY: Nitrosomonas europaea (Winogradsky) was isolated in pure culture from Rothamsted soil. The method used entailed: (1) building up the population of nitrifiers in enrichment cultures; (2) removal of the cells from the chalk in an enriched culture with a stream of carbon dioxide; (3) picking colonies from poured silica gel plates.
