J Phycol. 2009 Feb;45(1):193-202. doi: 10.1111/j.1529-8817.2008.00642.x.

The interaction between phenolic substances (PS) and alginates (ALG) has been suggested to play a role in the structure of the cell walls of brown seaweeds. However, no clear evidence for this interaction was reported. Vanadium bromoperoxidase (VBPO) has...

Cartilage. 2012 Jan;3(1):70-8. doi: 10.1177/1947603511418959.

OBJECTIVE: We have developed an ultrapurified low endotoxin alginate (UPLE alginate), which can drastically reduce endotoxin levels. Our purposes were to examine the effects of UPLE alginate administration on osteoarthritis (OA) progression and to determine the adequate molecular weight...

Alginate denotes a group of industrially important 1-4-linked biopolymers composed of the C-5-epimers β-D-mannuronic acid (M) and α-L-guluronic acid (G). The polysaccharide is manufactured from brown algae where it constitutes the main structural cell wall polymer. The physical properties...

Alginates are classed as a dietary fibre and have been shown to inhibit digestive enzymes

Exopolysaccharides Produced by Phytopathogenic Pseudomonas syringae Pathovars in Infected Leaves of Susceptible Hosts.

Plant physiology

Fett WF, Dunn MF.
PMID: 16666545
Plant Physiol. 1989 Jan;89(1):5-9. doi: 10.1104/pp.89.1.5.

Bacterial exopolysaccharide (EPS) was extracted from infected leaves of several host plants inoculated with phytopathogenic strains of Pseudomonas syringae pathovars. Extraction was by a facilitated diffusion procedure or by collection of intercellular fluid using a centrifugation method. The extracted...

A new electrochemical immunoassay strategy was proposed based on electrostatic interaction of natural polymers. The chitosan-entrapped carbon paste electrode (CCPE) was used as the base electrode, alginates as carriers for the reactants and horseradish peroxidase (HRP) as enzyme label...

Stability of hydrogels used in cell encapsulation: An in vitro comparison of alginate and agarose.

Biotechnology and bioengineering

Shoichet MS, Li RH, White ML, Winn SR.

Biotechnol Bioeng. 1996 May 20;50(4):374-81. doi: 10.1002/(SICI)1097-0290(19960520)50:4<374::AID-BIT4>3.0.CO;2-I.

The present studies were undertaken to evaluate the in vitro gel stability of the hydrogels alginate and agarose. Gel strength (of alginate and agarose) and protein diffusion (of alginate only) were shown to correlate with gel stability and to...

Bacterial Alginate Produced by a Mutant of Azotobacter vinelandii.

The optimum conditions in shaken flasks for production of bacterial alginate by mutant C-14 of Azotobacter vinelandii NCIB 9068 and a comparison of the properties of bacterial and algal alginates were investigated. The largest amount of bacterial alginate was...

Studies on the characteristics of alginate gels in relation to their use in separation and immobilized applications.

Studies on diffusion of NAD and hemoglobin from calcium and barium gels are reported where alginate grade, concentration, and gel dimensions were varied. These show that NAD diffusion characteristics are unaffected by alginate and ion concentrations; however, hemoglobin diffusion...

Alginate is a linear copolymer of 1-4 linked β-D-mannuronic acid (M) and 1-4 linked α-L-guluronic acid (G). The physical properties of these polysaccharides such as gel properties and viscosity are largely correlated to the monomer composition (M/G ratio), the...
