Sugar determination in ulvans by a chemical-enzymatic method coupled to high performance anion exchange chromatography

, 1997
International audienceThe sugar determination of ulvans, the water-soluble polysaccharides from Ulva sp. and Enteromorpha sp., was optimized by combining partial acid prehydrolysis (2 mol L-1 trifluoroacetic acid, 120°C) with enzymic hydrolysis (with β-D-

Characterization of an Alteromonas long-type ulvan lyase involved in the degradation of ulvan extracted from Ulva ohnoi [PDF]

Bioscience, Biotechnology, and Biochemistry, 2017
Abstract Ulvan is a sulfated polysaccharide found in the cell wall of the green algae Ulva. We first isolated several ulvan-utilizing Alteromonas sp. from the feces of small marine animals. The strain with the highest ulvan-degrading activity, KUL17, was analyzed further.

Overview on Biological Activities and Molecular Characteristics of Sulfated Polysaccharides from Marine Green Algae in Recent Years

Marine Drugs, 2014
Among the three main divisions of marine macroalgae (Chlorophyta, Phaeophyta and Rhodophyta), marine green algae are valuable sources of structurally diverse bioactive compounds and remain largely unexploited in nutraceutical and pharmaceutical areas ...

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Extraction and evaluation of biological properties of ulvans and oligo-ulvans from green seaweed Ulva sp. : actions on the metabolism of skin cells and on skin microbiota

, 2021
Les ulvanes sont des polysaccharides matriciels sulfatés constitutifs de la paroi de l’algue verte Ulva sp.. Bien que proliférative et quantitativement disponible, Ulva sp. est peu valorisée avec des applications dans des domaines à faible valeur ajoutée.

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

Food Safety and Health, EarlyView.
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 ...

Immunomodulating effect of a seaweed extract from Ulva armoricana in pig: Specific IgG and total IgA in colostrum, milk, and blood

Veterinary and Animal Science, 2019
The transfer of passive immunity from sows to piglets can be improved through the administration of immuno-stimulating products before farrowing. This study evaluated the immuno-stimulating effect of an algal sulfated polysaccharide extract (MSP extract)
