Ionomeric Films of Alginic Acid
Transparent, flexible films could be made by casting aqueous solutions of alginic acid, but they dissolved in water. When films were made from a solution of alginic acid and multivalent ions, they were still water soluble. However, when alginic acid films were immersed in a solution of salts with multivalent ions, they dissolved in water much more slowly, if at all. Treatment with calcium and z...
متن کاملAntibacterial Performance of Alginic Acid Coating on Polyethylene Film
Alginic acid coated polyethylene films were examined in terms of surface properties and bacteriostatic performance against two most representative bacterial strains, that is, Escherichia coli and Staphylococcus aureus. Microwave plasma treatment followed by brush formation in vapor state from three distinguished precursors (allylalcohol, allylamine, hydroxyethyl methacrylate) was carried out to...

متن کاملAlginic Acid Metabolism in Bacteria I. ENZYMATIC FORMATION OF UNSATURATED OLIGOSACCHARIDES AKD 4-DEOXY-L-ERYTHRO-5-HEXOSEULOSE URONIC ACID
Alginic acid, a high molecular weight linear polymer obtained from seaweed, is widely used as an added product to food due to its property of forming highly viscous solutions. Originally described as a polymer of n-mannuronic acid, it has now been demonstrated, by the chemical studies of Fischer and DGrfel (l), to be a ,&l-4-linked polymer of n-mannuronic and L-guluronic acid. The ratio of the ...
