Cold plasma‐induced modifications in the physico‐functional properties of glucan exopolysaccharide derived from Enterococcus hirae OL616073

Food Biomacromolecules, EarlyView.
Abstract This study evaluated the influence of cold plasma treatment on the physicochemical characteristics of glucan exopolysaccharide (EPS) produced by Enterococcus hirae OL616073 isolated from idli batter. The glucan EPS was exposed to pin‐to‐plate atmospheric cold plasma at 170–230 V for 5–15 min, generating cold plasma‐treated glucan (CPTG ...

Modified bacterial reaction centers [PDF]

, 1991
Pigments of borohydride-treated reaction centers of Rhodobacter sphaeroides R 26 and Rhodopseudomonas viridis were analyzed by HPLC with polychromatic detection. In both species, pigment composition and contents were unchanged.

Purification, Structural Characterization, and Anticancer Activity of the Polysaccharide From Sea Red Rice Bran

Food Frontiers, Volume 7, Issue 2, March 2026.
Sea red rice bran polysaccharides were separated and purified by DEAE‐52 column chromatography, yielding three components: SRBP‐I, II, and III. Moreover, all three are pentosan‐type polysaccharides predominantly composed of mannose. Among them, SRBP‐I demonstrated the most potent inhibitory effect on HeLa cells. Further investigation indicated that the

Microbial‐Immune Interplay in CNS Autoimmune Diseases: Lessons from Animal Models and Clinical Studies

European Journal of Immunology, Volume 56, Issue 2, February 2026.
Mechanism of action of the intestinal microbiota on CNS autoimmune diseases. Environmental factors shape gut microbiota composition; dysbiosis alters microbial metabolites and antigenic signals. These modulate innate and adaptive immunity, affect barrier integrity, and influence CNS‐resident cells such as microglia and astrocytes, contributing to ...

Almond Polysaccharide Ameliorates DSS‐Induced Ulcerative Colitis in Mice by Restoring Intestinal Barrier Function and Modulating Gut Microbiota and SCFAs Metabolism

Food Frontiers, Volume 7, Issue 1, January 2026.
This study shows that almond polysaccharide AP1 relieves DSS‐induced UC in mice by restoring the mucosal barrier, suppressing inflammation, and modulating gut microbiota and SCFA metabolism. ABSTRACT The development of new therapeutic strategies for ulcerative colitis (UC) requires the targeting of multiple pathogenic factors, including disruption of ...

Characterization of the extracellular lipase of Bacillus subtilis and its relationship to a membrane-bound lipase found in a mutant strain [PDF]

, 1979
Bacillus subtilis CMK33 is a mutant that is more osmotically fragile than the wild type when it is converted to the protoplast form. The protoplasts of this mutant contain a membrane-bound lipase, which is not found in protoplasts of the wild type ...

Clitocybe squamulosa Polysaccharides Ameliorate Dextran Sulfate Sodium‐Induced Colitis by Regulating the PI3K/AKt/mTOR Pathway and the Intestinal Flora in Mice

Food Frontiers, Volume 7, Issue 1, January 2026.
The potential mechanisms of CSFP and CE in alleviating UC. ABSTRACT Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by persistent inflammation and ulceration of the colon. This research investigated the protective effects of Clitocybe squamulosa fruiting body polysaccharide (CSFP) and purified polysaccharides named CE on ...
