Denitrification activity of a remarkably diverse fen denitrifier community in finnish lapland is N-oxide limited. [PDF]
PLoS ONE, 2015 Peatlands cover more than 30% of the Finnish land area and impact N2O fluxes. Denitrifiers release N2O as an intermediate or end product. In situ N2O emissions of a near pH neutral pristine fen soil in Finnish Lapland were marginal during gas chamber ...

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 ...

Impact of copper and iron on growth and silicic acid uptake in two Southern Ocean diatoms
Limnology and Oceanography, EarlyView.Abstract Copper (Cu) and iron (Fe) are vital micronutrients that influence diatom physiology, growth rate, and nutrient stoichiometry. This study examines the interactive effects of Cu and Fe on two Southern Ocean diatoms, Proboscia inermis and Chaetoceros flexuosus, cultured under varying Fe and Cu conditions.

Microbially Influenced Corrosion in Epoxy‐Ceramic Coated Carbon‐Steel Cooler
Materials and Corrosion, EarlyView.A significant localization of corrosion attacks up to 1 mm deep were found in coated carbon‐steel cooler. Corrosion products and biofilm were enriched in mixed bacterial community including the genera Sulfuritalea and Methylotenera. Analysis of metabolic markers confirmed their coexistence with sulfate‐reducing bacteria.

Life, 2015 Nitrogen starvation acclimation in non-diazotrophic cyanobacteria is characterized by a process termed chlorosis, where the light harvesting pigments are degraded and the cells gradually tune down photosynthetic and metabolic activities.

Virus-Encoded Ribonucleotide Reductases [PDF]
arXiv, 2014 Ribonucleotide reductases are encoded by many viruses, but without other enzymes of nucleotide metabolism of no obvious use. A look at the enzymes' molecular properties and their possible mutator action may give clues.

How native state topology affects the folding of Dihydrofolate Reductase and Interleukin-1beta [PDF]
, 2000 The overall structure of the transition state and intermediate ensembles experimentally observed for Dihydrofolate Reductase and Interleukin-1beta can be obtained utilizing simplified models which have almost no energetic frustration. The predictive power of these models suggest that, even for these very large proteins with completely different folding

Responsive Materials, EarlyView.By simulating the host defense strategy of human α‐defensin 6, biomimetic transformable peptide‐based aggregation‐induced emssion nanomaterials (PBANs) were prepared. PBANs self‐assembled into nanoparticles under physiological conditions, and in situ transformed into nanofiber on bacterial surfaces through receptor‐ligand interactions in infected ...

Reaction of the NAD(P)H:flavin oxidoreductase from Escherichia coli with NADPH and riboflavin: identification of intermediates [PDF]
Biochemistry, American Chemical Society, 1998, 37, pp.11879-87, 2014 Flavin reductase catalyzes the reduction of free flavins by NAD(P)H. As isolated, Escherichia coli flavin reductase does not contain any flavin prosthetic group but accommodates both the reduced pyridine nucleotide and the flavin substrate in a ternary complex prior to oxidoreduction.
