Promising substitute of inconsistent algal alginates: exploring the biocompatible properties of di-O-acetylated, poly-L-guluronate-deficient alginate from soil bacterium Pseudomonas aeruginosa CMG1418 [PDF]

BioTechnologia, 2023
The structural inconsistencies in commercial algal alginates have limited their reliability and quality for various applications. Therefore, the biosynthesis of structurally consistent alginates is crucial to replace the algal alginates. Thus, this study

Isolation and Structural Characterization of Alginates from the Kelp Species Laminaria ochroleuca and Saccorhiza polyschides from the Atlantic Coast of Morocco

Colloids and Interfaces, 2022
Alginates are linear unbranched polysaccharides produced by brown seaweeds. The gel properties of this phycocolloid are mainly linked to the monomer composition, sequential structure and molecular weight of the polymeric chain.

Genetic Regulation of Alginate Production in Azotobacter vinelandii a Bacterium of Biotechnological Interest: A Mini-Review

Frontiers in Microbiology, 2022
Alginates are a family of polymers composed of guluronate and mannuronate monomers joined by β (1–4) links. The different types of alginates have variations in their monomer content and molecular weight, which determine the rheological properties and ...

How alginate properties influence in situ internal gelation in crosslinked alginate microcapsules (CLAMs) formed by spray drying.

PLoS ONE, 2021
Alginates gel rapidly under ambient conditions and have widely documented potential to form protective matrices for sensitive bioactive cargo. Most commonly, alginate gelation occurs via calcium mediated electrostatic crosslinks between the linear ...
