Induction of Multiple Cytokine Secretion from RAW264.7 Cells by Alginate Oligosaccharides [PDF]

Bioscience, Biotechnology, and Biochemistry, 2007
We investigated the cytokine-inducing activities of guluronate (G3-G6) and mannuronate (M3-M6) oligomers on RAW264.7 cells with the Bio-Plex assay system. Relatively high levels of tumor necrosis factor-alpha (TNF-alpha), granulocyte colony-stimulating factor (G-CSF), monocyte chemoattractant protein-1 (MCP-1), regulated upon activation normal T cell ...

A bifunctional endolytic alginate lyase with two different lyase catalytic domains from Vibrio sp. H204

Frontiers in Microbiology
Alginate lyases can fully degrade alginate into various size-defined unsaturated oligosaccharide products by β-elimination. Here, we identified the bifunctional endolytic alginate lyase Aly35 from the marine bacterium Vibrio sp. Strain H204.

Engineered Probiotics: The Next‐Generation Therapeutics to Combat Antibiotic‐Resistant Bacterial Infections

Food Frontiers, Volume 7, Issue 2, March 2026.
Engineered probiotics secretes fusion proteins which potentially neutralized the toxins secreted by other microbial communities. ABSTRACT On a global scale, the escalating burden of infectious diseases, predominantly attributed to bacterial pathogens, especially drug‐resistant strains, has progressed into a critical concern for clinical management and ...

Expression, Purification, and Characterisation of Recombinant Alginate Lyase (Flammeovirga AL2) for the Bioconversion of Alginate into Alginate Oligosaccharides

Molecules
Alginate, a polysaccharide found in brown seaweeds, has regularly gained attention for its potential use as a source of bioactive compounds. However, it is structurally complex with a high molecular weight, limiting its application. Alginate oligosaccharides (AOS) are small, soluble fragments, making them more bioavailable.

Biostimulatory Potential of Sargassum muticum Extracts in Enhancing Sesame Tolerance to Water Deficit During Germination and Seedling Growth

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
Water deficit is a major abiotic stress that limits plant growth and productivity. This article evaluates the effectiveness of an aqueous seaweed extract (ASE) from Sargassum muticum as an ecofriendly biostimulant to alleviate water deficit stress during seed germination and early seedling growth of sesame (Sesamum indicum L.).
