Dielectric Relaxation, Water Sorption Thermodynamics, and Humidity‐Sensing Mechanisms of Compressed Ulva Biomass Pellets

open access: yesApplied Research, Volume 5, Issue 6, December 2026.
This study investigates the moisture sorption thermodynamics, dielectric relaxation behavior, and humidity‐sensing performance of compressed Ulva biomass pellets. The findings demonstrate that sustainable macroalgal pellets provide low hysteresis (~1.63%) and wide‐range sensitivity for green environmental diagnostics.

Production of Carbohydrate Building Blocks from Red Seaweed Polysaccharides. Efficient Conversion of Galactans into C-Glycosyl Aldehydes

open access: yes, 2009
Agarans and carrageenans are abundant natural polysaccharides which are obtained in large scale by water extraction from a variety of red seaweeds. These galactans in addition of being valuable products for pharmaceutical and food industries are low cost

Could the Extended Phenotype Extend to the Cellular and Subcellular Levels in Insect-Induced Galls?

open access: yesPLoS ONE, 2015
Neo-ontogenesis of plant galls involves redifferentiation of host plant tissues to express new phenotypes, when new cell properties are established via structural-functional remodeling.

Marine Non-Glycosaminoglycan Sulfated Glycans as Potential Pharmaceuticals

open access: yesPharmaceuticals, 2015
Sulfated fucans (SFs) and sulfated galactans (SGs) are currently the marine non-glycosaminoglycan (GAG) sulfated glycans most studied in glycomics.

Isolation, Structural Elucidation, and Anti‐Melanogenic Activity of a Novel Pectic Polysaccharide From Alhagi camelorum Fisch

open access: yesChemistry &Biodiversity, Volume 23, Issue 11, November 2026.
Polysaccharide extraction from Alhagi camelorum Fisch. was optimized, yielding ACP‐II‐1, a novel GalA‐rich, HG‐dominant pectin (26.145 kDa) containing branched RG‐I domains. ACP‐II‐1 reduced melanogenesis in forskolin‐stimulated B16F10 cells and a zebrafish model.

Structural Characterization and Immunomodulatory Activity of a Polysaccharide From Ipomoea batatas L. Vine: Activation of Macrophage

open access: yesFood Science &Nutrition, Volume 14, Issue 11, November 2026.
IBPS‐3A, an acidic heteropolysaccharide purified from sweet potato vines, was structurally characterized to possess a backbone consisting of →4)‐α‐D‐GalpA‐(1→ and →2,4)‐α‐L‐Rhap‐(1→ linkages with arabinogalactan side chains. Further investigation revealed that IBPS‐3A induced M1 polarization in RAW264.7 macrophages, stimulating the secretion of TNF‐α ...

Anticoagulant properties of a crude sulfated polysaccharide from the red marine alga Halymenia floresia (Clemente) C. Agardh - doi: 10.4025/actascibiolsci.v33i3.6402

open access: yesActa Scientiarum: Biological Sciences, 2011
Alternative sources of anticoagulants have arisen as a result of the increasing demand for safer anticoagulant clinical therapy, and the sulfated polysaccharides of seaweeds have gained attention in biomedicine.

Systematic Evaluation of Cyanidioschyzon merolae Across Photobioreactor Systems: Linking Reactor Design to Biomass Production and Biochemical Composition

open access: yesMicrobial Biotechnology, Volume 19, Issue 11, November 2026.
Systematic comparison of cultivation platforms revealed that photobioreactor design strongly influences growth, biomass productivity, and biochemical composition of the extremophilic red algae Cyanidioschyzon merolae. An internal‐illuminated photobioreactor achieved the highest biomass yields and starch levels, highlighting C.

Inhibitory Effect of Depolymerized Sulfated Galactans from Marine Red Algae on the Growth and Adhesion of Diarrheagenic Escherichia coli

open access: yes, 2019
Active polysaccharides as safe and natural polymers against bacterial diarrhea have been reconsidered as an alternative to antibiotics. This work investigated the inhibiting effect of depolymerized sulfated galactans from Eucheuma serra and Gracilaria ...
