Beyond Gut Modulation: A Critical Review of the Therapeutic Potential, Safety, and Clinical Prospects of Natural Polysaccharides for IBD

Food Safety and Health, Volume 4, Issue 4, Page 824-859, October 2026.
In this review, we critically summarized the application of natural polysaccharides (NPs) for the treatment of IBD. This approach combines, in a unique way (right), the basic structure–activity relationships of NPs from different origins (left) with their multipronged mode of action, which involves modulation of the gut microbiota and other ...

Exploration of Alkaliphilic Bacteria Alkalitalea saponilacus Identifies Glycoside Hydrolases With Biotechnological Potential

Microbial Biotechnology, Volume 19, Issue 9, September 2026.
Soda lakes represent an excellent resource in the search for microbes adapted to alkaline and hypersaline conditions. In this study we demonstrate the ability of Alkalitalea saponilacus to degrade multiple carbon sources representing a promising bacterium for biotechnological applications where performance under alkaline or strongly ionic conditions is

Structure and anticoagulant activity of sulfated galactans. Isolation of a unique sulfated galactan from the red algae Botryocladia occidentalis and comparison of its anticoagulant action with that of sulfated galactans from invertebrates.

The Journal of biological chemistry, 2000
We have characterized the structure of a sulfated d-galactan from the red algae Botryocladia occidentalis. The following repeating structure (-4-alpha-d-Galp-1-->3-beta-d-Galp-1-->) was found for this polysaccharide, but with a variable sulfation pattern.

Crystal structure of endo‐β‐1,6‐galactanase from Streptomyces avermitilis

Acta Crystallographica Section D, Volume 82, Issue 8, Page 962-971, August 2026.
The crystal structure of S. avermitilis endo‐β‐1,6‐galactanase belonging to GH30 subfamily 5 reveals the first structural framework for endo‐β‐1,6‐galactanase. The β‐1,6‐galactobiose‐bound complex identifies the catalytic subsites and a distal secondary sugar‐binding site, providing insight into β‐1,6‐galactan recognition.Endo‐β‐1,6‐galactanases ...

Glyco‐Nanogels for Modulating Pseudomonas aeruginosa Biofilm

Macromolecular Rapid Communications, Volume 47, Issue 14, 20 July 2026.
Nanogels presenting α‐galactose and β‐fucose can significantly alter Pseudomonas aeruginosa biofilm dynamics through their interaction with lectins. Application timing is crucial: pre‐treatment reduces biofilm, while treatment after biofilm initiation increases biomass.

Biochemical and structural characterization of a tail‐spike protein with depolymerase activity identified in a marine podovirus

Acta Crystallographica Section D, Volume 82, Issue 7, Page 785-799, July 2026.
The marine tail‐spike protein Dpo31 degrades the exopolysaccharide of its host and has structural features similar to those of other members of this protein class, despite similarity not being detected at the sequence level.Marine phages are, through the infection of their bacterial hosts, key regulators of microbiome and carbon fluxes in the ocean ...
