Quorum sensing systems regulate heterotrophic nitrification-aerobic denitrification by changing the activity of nitrogen-cycling enzymes

Environmental Science and Ecotechnology, 2020
Heterotrophic nitrification-aerobic denitrification (HNAD) is essential in diverse nitrogen-transforming processes. How HNAD is modulated by quorum sensing (QS) systems is still ambiguous.

Expression of a constitutively active nitrate reductase increases SARS‐CoV‐2 Spike protein production in Nicotiana benthamiana leaves that otherwise show traits of senescence

Plant Biotechnology Journal, EarlyView.
Summary The production of coronavirus disease 2019 vaccines can be achieved by transient expression of the Spike (S) protein of Severe Acute Respiratory Syndrome Coronavirus 2 in agroinfiltrated leaves of Nicotiana benthamiana, a process promoted by the co‐expression of viral silencing suppressor P19.

Seasonal variation in denitrification and dissimilatory nitrate reduction to ammonia process rates and corresponding key functional genes along an estuarine nitrate gradient

Frontiers in Microbiology, 2015
This research investigated spatial-temporal variation in benthic bacterial community structure, rates of denitrification and dissimilatory nitrate reduction to ammonium (DNRA) processes and abundances of corresponding genes and transcripts at three sites

Biochemical properties of Paracoccus denitrificans FnrP:Reactions with molecular oxygen and nitric oxide [PDF]

, 2016
In Paracoccus denitrificans, three CRP/FNR family regulatory proteins, NarR, NnrR and FnrP, control the switch between aerobic and anaerobic (denitrification) respiration.

Characterization of transcriptional and metabolic responses to a complex plant growth‐promoting soil inoculum

Plant Biology, EarlyView.
Characterization of transcriptional and metabolic responses to a complex plant growth‐promoting soil inoculum. Host transcriptional modules involved in photosynthesis, protein regulation, and mineral nutrition are associated with plant growth in response to beneficial soil microbes.

The effect of ionic and non-ionic surfactants on the growth, nitrate reductase and nitrite reductase activities of Spirodela polyrrhiza (L.) Schleiden

Acta Societatis Botanicorum Poloniae, 2014
Inclusion into the medium of 5 mg•dm-3 of non-ionic (ENF) or ionic (DBST) surfactant caused 50-60% inhibition of nitrite reductase MR) activity in S. polyrrhiza.

Dietary nitrate supplementation mitigates age‐related changes at the neuromuscular junction in mice

The Journal of Physiology, EarlyView.
Abstract figure legend Ageing is associated with a decline in muscle mass and strength, namely sarcopenia, significantly impacting the quality of life in older individuals. Different strategies are being explored to counteract these detrimental effects. In the present study, we investigated a non‐invasive nutritional approach: the impact of 2 months of

Modelling N2O dynamics of activated sludge biomass under nitrifying and denitrifying conditions: pathway contributions and uncertainty analysis [PDF]

arXiv, 2018
Nitrous oxide (N2O) is a potent greenhouse gas emitted during biological wastewater treatment. A pseudo-mechanistic model describing three biological pathways for nitric oxide (NO) and N2O production was calibrated for mixed culture biomass from an activated sludge process using laboratory-scale experiments.
