Effect of Sodium Chloride on Nitrate, Ions Accumulation and Nitrate Reductase Activity in Two Rootstocks of Almond [PDF]

Zīst/shināsī-i Giyāhī-i Īrān, 2019
Limited data published about the effects of salinity on nitrogen assimilation of fruit trees such as almond. A greenhouse experiment was conducted to study the effect of sodium chloride (0, 75 and 150 mM NaCl) on nitrate reductase activity, accumulation ...

Eleven-year, 22-year and ~90-year solar cycles discovered in nitrate concentrations in a Dome Fuji (Antarctica) ice core [PDF]

arXiv, 2022
Ice cores are known to yield information about astronomical phenomena as well as information about past climate. We report time series analyses of annually resolved nitrate variations in an ice core, drilled at the Dome Fuji station in East Antarctica, corresponding to the period from CE 1610 to 1904.

Direct Quantification of Protein–Protein Interactions in Living Bacterial Cells

Advanced Science, EarlyView.
Quantitative measurement of protein–protein interactions in living cells is vital for biotechnology applications. Fluorescence resonance energy transfer (FRET) signals in bacterial cells are often weak, leading to false‐positive. Quantitative FRET measurements are implemented to overcome the weak FRET signal.

Microbial Reduction of Chromate in the presence of Nitrate by Three Nitrate Respiring Organisms.

Frontiers in Microbiology, 2012
A major challenge for the bioremediation of toxic metals is the co-occurrence of nitrate, as it can inhibit metal transformation. Geobacter metallireducens, Desulfovibrio desulfuricans, and Sulfurospirillum barnesii are three soil bacteria that can ...

Antagonist Targeting the Species‐Specific Fatty Acid Dehydrogenase/Isomerase FabX for Anti‐H. pylori Infection

Advanced Science, EarlyView.
This study demonstrates that the atypical dehydrogenase/isomerase FabX in Type‐II fatty acid biosynthesis pathway is essential for H. pylori infection by retaining unsaturated fatty acid synthesis and producing superoxide (ROS). A small molecule FBX‐1991 that specifically targets FabX to inhibit H.

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

Identification and Application of a Novel Patulin Degrading Enzyme From Meyerozyma guilliermondii

Advanced Science, EarlyView.
Patulin (PAT), a hazardous mycotoxin, threatens human health. A novel yeast‐derived short‐chain dehydrogenase/reductase effectively degrades PAT into nontoxic ascladiol via catalytic triad activity. The biological detoxification process has no significant effect on the quality of fresh pear juice.

Single‐Cell Transcriptome Reveals Aquaporin‐Mediated Carbon Nanosol‐Induced Growth Promotion of Plants

Advanced Science, EarlyView.
Carbon nanosol (CNS) exhibits rapid root penetration capacity, enhancing plant growth through boosting stomatal density and antioxidative enzyme activity. Single‐cell transcriptomic profiling uncovers cell type‐specific gene expression patterns and developmental trajectories during CNS‐mediated growth promotion.

In silico prediction of silver nitrate nanoparticles and Nitrate Reductase A (NAR A) interaction in the treatment of infectious disease causing clinical strains of E. coli

Journal of Infection and Public Health, 2020
Background: The interaction of specially designed nanoparticles with proteins is the basis of formation of a nanoparticle-protein corona. Silver nanoparticles and molecules have been used in many fields due to their strong antimicrobial activity against ...
