Validation of the names Cyanobacterium and Cyanobacterium stanieri, and proposal of Cyanobacteriota phyl. nov.

International Journal of Systematic and Evolutionary Microbiology, 2022
The decision by the International Committee on Systematics of Prokaryotes (ICSP) to place the rank of phylum under the rules of the International Code of Nomenclature of Prokaryotes (ICNP), with phylum names ending in –ota based on the name of a type genus, enables the valid publication of the phylum name Cyanobacteriota with

From Food Waste to Valorized Nanomaterials: Sustainable Green Synthesis and Biomedical Applications

ChemFoodChem, EarlyView.
Food waste‐derived biomolecules act as natural reducing and stabilizing agents for the green synthesis of functional NPs with applications in antimicrobial systems, food packaging, biomedical technologies, and environmental remediation. ABSTRACT Food waste is a global issue, with billions of tons discarded and unutilized annually, causing economic ...

Single GAF Domain Phytochrome Exhibits a pH‐Dependent Shunt on the Millisecond Timescale

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
During their light‐induced photocycle, phytochromes can engage in a thermal reversion back to the initially excited state, denoted as a shunt. This study investigates a pH‐dependent shunt transition in the Pfr state of the All2699g1 phytochrome from Nostoc punctiforme using UV/Vis laser flash photolysis and kinetic modeling. The findings suggest a keto‐

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

Journal of Raman Spectroscopy, EarlyView.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman

Biosynthesis of a linoleic acid allylic epoxide: mechanistic comparison with its chemical synthesis and leukotriene A biosynthesis[S]

Journal of Lipid Research, 2009
Biosynthesis of the leukotriene A (LTA) class of epoxide is a lipoxygenase-catalyzed transformation requiring a fatty acid hydroperoxide substrate containing at least three double bonds. Here, we report on biosynthesis of a dienoic analog of LTA epoxides

Production of the freshwater microalgae Scenedesmus dimorphus and Arthrospira platensis by using cattle digestate [PDF]

, 2014
Microalgae are considered one of the most promising feedstocks for biofuels; these microorganisms are also able to enhance the nutritional content of conventional food preparations, or can be converted into other fuel products, such as hydrogen, ethanol,

Sodium-coupled motility in a swimming cyanobacterium [PDF]

Journal of Bacteriology, 1987
The energetics of motility in Synechococcus strain WH8113 were studied to understand the unique nonflagellar swimming of this cyanobacterium. There was a specific sodium requirement for motility such that cells were immotile below 10 mM external sodium and cell speed increased with increasing sodium levels above 10 mM to a maximum of about 15 microns/s

Cardioprotective effect of spirulina on cafeteria diet‐induced cardiac injury in silico and in vivo study

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Obesity is a major risk factor for cardiovascular disease, primarily due to its effects on lipid metabolism, oxidative stress, and inflammation. The aim of this study was to evaluate the effects of spirulina (SP) on cafeteria diet (CD)‐induced myocardial oxidative stress and inflammation using biochemical, histological, and in ...
