Ca(II) and Ce(III) homogeneous alginate hydrogels from parent alginic acid precursor: a structural study
(Royal Society of Chemistry, 2016-04)
Alginate hydrogels are suitable for the encapsulation of biomolecules and microorganisms for the building of bioactive materials. Several alternatives to the conventional alginate formulation are being studied for a broad ...
Review of the characterization of sodium alginate by intrinsic viscosity measurements: Comparative analysis between conventional and single point methods
(Open Science Publishing, 2014-05)
In the pharmaceutical and food industry, alginate is used in aqueous solutions and excipients as thickener, gelling agent, coagulant and encapsulant. This biopolymer is very important, with many key industrial applications, ...
Immobilization of Bradyrhizobium and Azospirillum in alginate matrix for long time of storage maintains cell viability and interaction with peanut
(Springer, 2020-10)
Immobilizarion of PGPR for agricultural applications aims to provide temporary physical protection from stressful environmental conditions and the gradual release of cells for successful root colonization, release the cells ...
Development of alginate microparticles as efficient adsorption matrix for protein recovery
(Elsevier, 2019-05)
Alginate microparticles were prepared by spray drying technique and chemically cross-linked with epichlorohydrin. Microparticles were characterized by size, surface morphology (SEM), zeta potential, thermal analysis (TGA/DSC) ...
Oxidation of sodium alginate and characterization of the oxidized derivatives
(Elsevier, 2007-02-01)
Oxidation reactions on -OH groups at C-2 and C-3 positions of the uronic units of sodium alginate were performed with sodium periodate, and the influence of degree of oxidation on physical properties of the oxidized ...
Purification of chymotrypsin from pancreas homogenate by adsorption onto non-soluble alginate beads
(Elsevier, 2011-03)
Chymotrypsin was purified from an activated homogenate of bovine pancreas by adsorption onto non-soluble alginate beads in 25 mM Tris-acetate-5 mM CaCl2 buffer at different adsorbate-adsorbent ratios and the pH values were ...
Purification of alginate improves its biocompatibility and eliminates cytotoxicity in matrix for bone tissue engineering
(Elsevier, 2019-06)
There is a growing interest about using natural polymers from renewable sources as biomaterials for applications in tissue engineering. In the present work, alginates were extracted from Undaria pinnatifida, a brown sea ...
Structure and permeability of Low-Methoxyl Pectin (LMP)-Sodium alginates (NaAlg) films
(Associazione Italiana Di Ingegneria Chimica, 2009-12)
Alginate and pectin form synergistic mixed gels that lead to a microstructure totally different from that of pure biopolymers. Synergistic mixed gels are of particular interest as makers of films with new improved ...
Synthesis and characterization of a β-CD-alginate conjugate
(Elsevier, 2006-12-07)
Selective chemical modification of both β-cyclodextrin (β-CD) and sodium alginate (alg) was performed in order to produce an alginate derivative possessing pendant β-CD cavities along the chain. The latter was then fully ...
Encapsulation of florfenicol by in situ crystallization into novel alginate-Eudragit RS® blended matrix for pH modulated release
(Editions Sante, 2019-12)
Florfenicol (FF) is a broad-spectrum antibiotic with the drawback of poor solubility in physiological media. Despite vehiculization of FF become an alternative, current devices usually showed low encapsulation efficiencies(EE) ...
