Bioprospecting Ulleungdo‐isolated microalgae for carbon valorization and utilization

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The growing demand for renewable energy alternatives has intensified global interest in microalgae as versatile bioresources for carbon valorization and bioenergy production. Owing to their rapid growth and biochemical versatility, microalgae provide a sustainable route for converting captured carbon into bioenergy and high‐value products ...

Acyl lipids in the supramolecular chlorophyll-protein complexes of photosystems - isolation artifacts or integral components regulating their structure and functions?

open access: yesActa Societatis Botanicorum Poloniae, 2014
The precise nature of interactions between the chloropnyll-protein complexes related to photosystem I or photosystem II and the acyl lipids in the thylakoid membranes is not yet fully elucidated.

Photosystem II — Mediated cyclic photophosphorylation [PDF]

open access: yesBiochemical and Biophysical Research Communications, 1976
DCMU-sensitive synthesis of ATP can be shown to continue in KCN-treated chloroplasts after cessation of O2 evolution. The catalyst for this reaction, p-phenylenediamine, also stimulates synthesis of ATP in NH2OH-treated chloroplasts, but at much higher rates.

Modeling of Transient Absorption Spectra in Exciton Charge-Transfer Systems

open access: yes, 2017
Time-resolved spectroscopy provides the main tool for analyzing the dynamics of excitonic energy transfer in light-harvesting complexes. To infer time-scales and effective coupling parameters from experimental data requires to develop numerical exact ...

Ligand architecture and secondary‐sphere effects in a well‐defined cobalt(IV)–oxo complex

open access: yesBulletin of the Korean Chemical Society, EarlyView.
A well‐defined cobalt(IV)–oxo complex supported by a neutral tetraazamacrocyclic ligand is generated and fully characterized. The cobalt(IV)–oxo species exhibits electrophilic oxygen‐atom and hydrogen‐atom transfer reactivity, strongly modulated by protonation and secondary coordination sphere effects, providing new insight into structure–reactivity ...

Non-intrusive Assessment of Photosystem II and Photosystem I in Whole Coral Tissues

open access: yesFrontiers in Marine Science, 2017
Reef building corals (phylum Cnidaria) harbor endosymbiotic dinoflagellate algae (genus Symbiodinium) that generate photosynthetic products to fuel their host's metabolism.

Models and measurements of energy-dependent quenching. [PDF]

open access: yes, 2013
Energy-dependent quenching (qE) in photosystem II (PSII) is a pH-dependent response that enables plants to regulate light harvesting in response to rapid fluctuations in light intensity.

Cytotoxicity of 19 Pesticides in Rainbow Trout Gill, Liver, and Intestinal Cell Lines

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract The rainbow trout gill cell line (RTgill‐W1), via test guideline 249 of the Organisation for Economic Co‐operation and Development, has been established as a promising New Approach Methodology, although to advance confidence in the method more case studies are needed that: 1) expand our understanding of applicability domains (chemicals with ...

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Redox Tuning in Photosystem II

open access: yesTrends in Plant Science, 2017
In photosynthesis, oxygen is liberated from water, not from CO2; however, this model has been silent on why photosynthesis requires bicarbonate. Rutherford and colleagues solve this problem elegantly: bicarbonate tunes water-oxidising photosystem II to make onward electron transfer efficient; an absence of bicarbonate retunes, redirects, and safely ...
