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...

Critical discussion on pancreatic islets/insulin producing cells microencapsulation within highly purified alginic acid-derived bioplymers: past, present and future.

Sodium alginate, mannuronic acid-rich and guluronic acid-rich fractions were prepared from "Mekabu" (sporophyll of Undaria pinnatifida). The production of short-chain fatty acids such as acetic, propionic and n-butyric acids from these fractions in mini-scale batch culture using pig cecal bacteria was studied, and the gas released from the culture was monitored. The volume of released gas corre...
