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.

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

Characterization of Alginates of Sargassum from the Archipelago of Guadeloupe

Separations
Sargassum is a genus of brown algae that causes a major impact to marine ecosystems. Although accumulation of this invasive seaweed is considered an environmental problem, Sargassum can also be resource of valuable molecules such as alginates.

Alginate supramolecular hydrogels based on viologen and cucurbit[8]uril: Host‐induced caveolae‐mediated endocytosis to white blood cancer cells

View, 2023
The cellular uptake of drug carriers to the cytosol of a specific cell remains challenging, and a non‐classical supramolecular strategy is motivated. Here, we select a model host–guest complex in which a diamino‐viologen (1,1′‐bis(4‐aminophenyl)‐[4,4 ...

Applications of Alginate-Based Nanomaterials in Enhancing the Therapeutic Effects of Bee Products

Frontiers in Molecular Biosciences, 2022
Since the ancient times, bee products (i.e., honey, propolis, pollen, bee venom, bee bread, and royal jelly) have been considered as natural remedies with therapeutic effects against a number of diseases. The therapeutic pleiotropy of bee products is due
