Technological activities of Staphylococcus carnosus and Staphylococcus simulans strains isolated from fermented sausages [PDF]

open access: yes, 2005
The aim of this study was to determine the technological properties of 2 strains of Staphylococcus simulans (Ssm12, Ssm21) and 4 strains of S. carnosus (SC28, SC31, SC54 and SC55) for the selection of a potential starter cultures to employ in the ...

Miniview: algal nitrate reductases [PDF]

open access: yesEuropean Journal of Phycology, 1997
The past decade has seen substantial breakthroughs in understanding the biochemistry, molecular biology and regulation of nitrate reductases (NR) in higher plants and green algae. In contrast, although there has been considerable interest in using various measurements of NR to provide ecophysiological information, comparable knowledge of NR is largely ...

Covalent Organic Frameworks for Photocatalysis

open access: yesAdvanced Materials, EarlyView.
This review provides an overview of recent advances in covalent organic frameworks (COFs) for photocatalysis, focusing on sustainable energy applications like water splitting, hydrogen peroxide generation, and CO2 and N2 reduction. It discusses design principles, structure‐function relationships, challenges in COF photocatalysis, and strategies to ...

Soil acidity as affecting micronutrients concentration, nitrato reductase enzyme activity and yield in upland rice plants

open access: yesSemina: Ciências Agrárias, 2013
The lowest grain yield of rice under no-tillage system (NTS) in relation to the conventional system may be due to the predominance nitrate in the soil and the low nitrate reductase activity.

Inhibition of gibberellin biosynthesis by nitrate in Gibberella fujikuroi [PDF]

open access: yes, 1997
Gibberellin production in Gibberella fujikuroi starts upon exhaustion of the nitrogen source. To determine the role of nitrate and ammonium in the regulation of gibberellin biosynthesis we have isolated mutants that cannot use nitrate as a nitrogen ...

Nitrate assimilatory genes and their transcriptional regulation in a unicellular red alga Cyanidioschyzon merolae: genetic evidence for nitrite reduction by a sulfite reductase-like enzyme.

open access: yesPlant and Cell Physiology, 2010
Cyanidioschyzon merolae is a unicellular red alga living in acid hot springs, which is able to grow on ammonium, as well as nitrate as sole nitrogen source. Based on the complete genome sequence, proteins for nitrate utilization, nitrate transporter (NRT)

Advancements in Understanding the Physicochemical Properties of Reticular Materials: An In Situ and Operando Spectroscopic Perspective

open access: yesAdvanced Materials, EarlyView.
This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

Clustering as a Means To Control Nitrate Respiration Efficiency and Toxicity in Escherichia coli

open access: yesmBio, 2019
Respiration is a fundamental process that has to optimally respond to metabolic demand and environmental changes. We previously showed that nitrate respiration, crucial for gut colonization by enterobacteria, is controlled by polar clustering of the ...

Cyanate Assimilation by the Alkaliphilic Cyanide-Degrading Bacterium Pseudomonas pseudoalcaligenes CECT5344: Mutational Analysis of the cyn Gene Cluster [PDF]

open access: yes, 2019
The alkaliphilic bacterium Pseudomonas pseudoalcaligenes CECT5344 can grow with cyanate, cyanide, or cyanide-containing industrial residues as the sole nitrogen source, but the assimilation of cyanide and cyanate takes place through independent pathways.
