Coming to Terms: The Mechanisms of Overplus and Luxury Phosphorus Uptake for Polyphosphate Storage in Microalgae and Yeast

Biotechnology and Bioengineering, EarlyView.
Plouviez et al. give a perspective on the terminology used for describing the mechanisms of polyphosphate accumulation in microalgae and yeast. Their differentiation of mechanisms is based on environmental P availability, polyP chemistry, genetics, or cellular function as described in recent literature.

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 ...

Amazonian Cyanobacteria as a Source of Bioactive Compounds With Antimicrobial and Cytotoxic Properties

Chemistry &Biodiversity, EarlyView.
ABSTRACT Cyanobacteria are photosynthetic microorganisms known for producing diverse bioactive compounds. This study explores the bioactivity of extracts and fractions from Amazonian cyanobacteria and their pigment and phenolic compound production. A fraction from Synechococcus sp. CACIAM 05 showed cytotoxicity against hCMEC/D3 and MG‐63 cells.

Impacts of dietary cyanobacteria on fish

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010
Development of cyanobacterial water bloom became a common issue all over the world. Cyanobacteria are the most important primary producers in aquatic ecosystems but in some abundant species their secondary metabolites called cyanotoxins seem to be ...

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‐

Nature‐Inspired Uv Filters: Synthetic Mycosporine‐Like Amino Acids and Gadusol Analogs for Enhanced Photoprotective and Antioxidant Performance

ChemPhotoChem, EarlyView.
Photoprotection is a current and relevant topic; therefore, the development of new sunscreens is necessary. To this end, nature is examined for molecules such as mycosporine‐like amino acids and gadusol. Through rational design, this study has successfully synthesized new UV filters and evaluated their photoprotective and antioxidant properties ...

Late Pleistocene to Holocene sedimentation in the Great Blue Hole (Lighthouse Reef, Belize): Results from a 30 m long core

The Depositional Record, EarlyView.
A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes
