Genetic and environmental controls on nitrous oxide accumulation in lakes. [PDF]
PLoS ONE, 2015 We studied potential links between environmental factors, nitrous oxide (N2O) accumulation, and genetic indicators of nitrite and N2O reducing bacteria in 12 boreal lakes.

In vitro Nitrate Reductase Activity Assay of Mycolicibacterium smegmatis Crude Extract
Bio-Protocol, 2021 Nitrate is one of the major inorganic nitrogen sources for microorganisms. Many bacterial and archaeal lineages can express cytoplasmic assimilatory nitrate reductase (NAS), which catalyzes the rate-limiting reduction of nitrate to nitrite in the nitrate

An investigation into the unusual linkage isomerization and nitrite reduction activity of a novel tris(2-pyridyl) copper complex [PDF]
, 2017 The copper-containing nitrite reductases (CuNIRs) are a class of enzymes that mediate the reduction of nitrite to nitric oxide in biological systems. Metal–ligand complexes that reproduce the salient features of the active site of CuNIRs are therefore of

Possible contribution of olefins and heteroatoms to the Unidentified Infrared Bands [PDF]
Astron.Astrophys.402:L13-L16,2003, 2003 The current assignments of the 11.3 feature are shown to be incompatible with observations. An unbiased survey of correlation charts suggests that the olefinic group R2=CH2 is a good alternative candidate. For the 12.7 feature, the best fits are provided by nitrites, R-O-N=O, and amines, R-N=H2.

Role of Nitrate and Nitrite in the Induction of Nitrite Reductase in Leaves of Barley Seedlings [PDF]
Plant Physiology, 1989 The role of NO3- and NO2- in the induction of nitrite reductase (NiR) activity in detached leaves of 8-day-old barley (Hordeum vulgare L.) seedlings was investigated. Barley leaves contained 6 to 8 micromoles NO2-/gram fresh weight x hour of endogenous NiR activity when grown in N-free solutions.

iMetaOmics, EarlyView.We generated the first comprehensive view of RNA viral auxiliary metabolic genes (AMGs), expanding the known functional type of AMGs by 75%. RNA viruses encode a remarkably high diversity of AMGs, spanning 25 distinct functional categories. Most of these genes are linked to environmental regulation and genetic information processing, with fewer ...

Does a glycine sodium nitrite crystal exist? [PDF]
arXiv, 2015 The glycine sodium nitrite crystal reported by Khandpekar and Pati in the paper entitled, Synthesis and characterisation of glycine sodium nitrite crystals having non linear optical behaviour, Opt Commun 285, 2012 288-293 is actually gamma-glycine. In addition, we show that glycine barium ammonium nitrate, glycine sodium zinc sulfate, glycine barium ...

Silver(I) complexes with nitrile ligands: new materials with versatile applications [PDF]
Appl Organomet Chem. 2023;37:e7207In the present study, the structure, thermal stability, conductive properties, and antimicrobial activity of silver(I) complexes with nitrile ligands were investigated. For the construction of the materials, 2 cyanopyridine (2-cpy), 4-cyanopyridine (4-cpy), 1,2-dicyanobenzene (1,2-dcb), and 1,3 dicyanobenzene (1,3-dcb) were used in addition to the ...

Processes and microorganisms driving nitrous oxide production in the Benguela Upwelling System
Limnology and Oceanography, EarlyView.Abstract Upwelling systems and their associated oxygen deficient zones (ODZs) are hotspots of nitrous oxide (N2O) production in the ocean. The Benguela Upwelling System (BUS) is a highly productive region and an important, yet variable source of N2O to the atmosphere.
