Potential of Seaweed to Improve the Quality and Shelf Life of Fish and Fishery Products

open access: yesFood Safety and Health, EarlyView.
Growing global demand for safe fish preservation has increased interest in natural alternatives. Seaweed‐derived bioactive compounds possess antioxidant and antimicrobial properties that enhance fish quality, safety, and shelf life. These sustainable preservatives may reduce spoilage and synthetic preservative use, though further research ...

Responses of primary producers, anoxia, and chemical feedback to Late Glacial climate change: Insights from a paired lake approach

open access: yesJournal of Quaternary Science, EarlyView.
Abstract Worldwide, lacustrine ecosystems are threatened by eutrophication and deoxygenation. Both processes are driven by the combined effects of human activities and climate change. Understanding the pre‐anthropogenic nexus between warming, eutrophication, deoxygenation, and related feedback is essential to determine how lakes respond to rapid ...

High Molecular Weight λ-Carrageenan Improves the Color Stability of Phycocyanin by Associative Interactions

open access: yesFrontiers in Sustainable Food Systems, 2022
Phycocyanin is a protein-chromophore structure present in Arthrospira platensis commonly used as a blue-colorant in food. Color losses of phycocyanin can be reduced by electrostatic complexation with λ-carrageenan.

Near‐infrared confocal imaging reveals the spatial organisation of far‐red photosynthesis in Shark Bay microbial mats and Halomicronema sp.

open access: yesJournal of Microscopy, EarlyView.
Abstract Far‐red light (FRL) cyanobacteria occupy spectrally filtered habitats where visible wavelengths are depleted but far‐red radiation persists. Shark Bay (Western Australia) stromatolitic microbial mats provide such a habitat, containing subsurface cyanobacterial communities in which chlorophyll d/f (Chl d/f)‐containing phototrophs coexist with ...

Thermophilic C-phycocyanin: effect of temperature, monomer stability, and structure [PDF]

open access: yes, 1997
C-Phycocyanin has been purified from Synechococcus lividus (SyI), which grows between 66 and 73°C at the highest temperature of any cyanobacterium and of any biliprotein-containing organism. The protein was examined at its physiological temperature, 70°C,

Non-inhibitory effects of the potent antioxidant C-phycocyanin from Plectonema sp. on the in vitro glycation reaction

open access: yesRomanian Journal of Laboratory Medicine, 2022
When glucose and Amadori products are auto-oxidized, glycation occurs, resulting in the formation of early (Amadori) and late advanced glycation end products (AGEs), as well as free radicals.

Recent Advances in Microalgae‐Based Functional Coatings and Films for Food Packaging Applications: Opportunities and Challenges

open access: yesPackaging Technology and Science, Volume 39, Issue 11, Page 1377-1396, November 2026.
Microalgae‐derived bioactive compounds exhibit strong antioxidant and antimicrobial properties and can be incorporated into edible coatings to enhance food quality and shelf life. These materials offer sustainable, biodegradable alternatives to conventional packaging, with promising potential for future scalable food applications.

Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2119-2133, October 2026.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Transcriptome Analysis of Phycocyanin-Mediated Inhibitory Functions on Non-Small Cell Lung Cancer A549 Cell Growth

open access: yesMarine Drugs, 2018
Phycocyanin (PC), derived from cyanobacteria and Spirulina cells, is a type of natural antineoplastic marine protein. It has been reported that phycocyanin exerts an antitumor function in non-small cell lung cancer (NSCLC) cells, but the underlying ...

Bioactive peptides in cancer and inflammation: Mechanisms, model systems and clinical translation

open access: yesClinical and Translational Discovery, Volume 6, Issue 5, October 2026.
Bioactive peptides (BAPs) derived from host, marine, insect, plant and synthetic sources share cationic, amphipathic structures adopting α‐helical, β‐sheet or cyclic conformations. These features underlie anti‐cancer effects, including membrane disruption, apoptosis and cell‐cycle arrest, anti‐metastatic activity, reduced invasion and migration, and ...
