The circadian clock of cyanobacteria [PDF]
BioEssays, 2000 A circadian clock, with physiological characteristics similar to those of eukaryotes, functions in the photosynthetic prokaryote, cyanobacteria. The molecular mechanism of this clock has been efficiently dissected using a luciferase reporter gene that reports the status of the clock.

On the robustness of the in vivo cyanobacterial circadian clock [PDF]
arXiv, 2022 We propose a revisited version of the in vivo model of the cyanobacterial circadian clock. Our aim is to address the lack of robustness predicted for the mutant cyanobacteria without transcriptional regulation of the original model. For this, we rely on an in vitro model of the clock describing explicitly the hexameric structure of the core protein of ...

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‐

Chemical Looping Co-Gasification Characteristics of Cyanobacterial/Coal Blends
Energies, 2020 The frequent outbreak of cyanobacteria bloom results in an urgent need for the resource utilization of cyanobacteria. However, the development of routine thermal treatment (i.e., gasification and pyrolysis) is hindered by the issue of high moisture ...

Physical measures to inhibit planktonic cyanobacteriae [PDF]
, 1992 In a small lake, intermittent destratification was installed after several other physico-chemical and physical in-lake therapy measures (phosphorus immobilization, permanent destratification) had been tested without great success.

Topological transition in filamentous cyanobacteria: from motion to structure [PDF]
Many active systems are capable of forming intriguing patterns at scales significantly larger than the size of their individual constituents. Cyanobacteria are one of the most ancient and important phyla of organisms that has allowed the evolution of more complex life forms. Despite its importance, the role of motility on the pattern formation of their

ChemPlusChem, EarlyView.Gold nanoparticles (AuNPs) are widely used in biomedicine, electronics, catalysis, and environmental science. Conventional synthesis relies on harsh chemicals, driving interest in eco‐friendly methods using plants, bacteria, fungi, and algae. Biomolecules like polyphenols, proteins, and fatty acids aid nanoparticle synthesis under mild conditions. This

Management of Biesboch reservoirs for quality control with special reference to eutrophication [PDF]
, 1992 The three Biesbosch Reservoirs are pumped storage reservoirs, fed with rather polluted and highly eutrophic water from the River Meuse. Air injection at the bottom of the reservoirs prevents thermal stratification, which would otherwise result in serious

The Potential Use of Marine Microalgae and Cyanobacteria in Cosmetics and Thalassotherapy
, 2017 The use of microalgae and cyanobacteria for nutritional purposes dates back thousands of years; during the last few decades, microalgae culture has improved to become one of the modern biotechnologies. This has allowed high amounts of algal biomass to be
