Radical Depolymerization of Alginate Extracted from Moroccan Brown Seaweed Bifurcaria bifurcata

Applied Sciences, 2020
The degradation of alginate extracted from Moroccan Bifurcaria bifurcata has not been fully established to date. In this work, we report the extraction and the characterization of alginate (ASBB) from the brown algae B.

Alginates as Green Flocculants for Metal Oxide Nanoparticles [PDF]

, 2023
Flocculation is used for the removal or separation of colloids, e.g. in water treatment and mineral processing. Alginates are linear, anionic biopolymers composed of mannuronic (M) and guluronic (G) acids.

Improving The Antioxidant Activity of Sodium Alginate from Sargassum sp. by Thermal Heating and Chemical Methods

Jurnal Kelautan Tropis, 2020
The relationship between molecular structure and bioactivity was evaluated for sodium alginates obtained under different degradation treatment (raw alginates, heat-treated, and chemical-treated) from Sargassum sp. This study was conducted to identify the

Exploiting Mannuronan C-5 Epimerases in Commercial Alginate Production

Marine Drugs, 2020
Alginates are one of the major polysaccharide constituents of marine brown algae in commercial manufacturing. However, the content and composition of alginates differ according to the distinct parts of these macroalgae and have a direct impact on the ...

Molecular weight and viscosifying power of alginates produced by mutant strains of Azotobacter vinelandii under microaerophilic conditions

Biotechnology Reports, 2020
Alginates are polysaccharides that are of interest in various industrial applications. This is due to the viscosifying properties of alginates, which depends on the weight-average molecular weight. The aim of the present study was to evaluate the changes

Alginates in Metabolic Syndrome

, 2017
Alginates extracted from seaweeds are widely used for nutrition, but they are underutilised for the prevention or reversal of human disease. Alginates are long chains of α-L-guluronic acid and β-D-mannuronic acid from brown seaweeds that act as readily ...

Water sorption isotherms of different sodium alginates : thermodynamic evaluation and influence of mannuronate-guluronate copolymers [PDF]

, 2022
Water desorption isotherms of three alginates with different structural features were determined at 25, 37, and 50°C. The Halsey model was selected to fit the equilibrium water sorption data.
