Antibacterial Performance of Alginic Acid Coating on Polyethylene Film [PDF]
International Journal of Molecular Sciences, 2014 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

Alginic acid and mononitrated alginic acid were reacted with η-amyl-iodide, β-diethylaminoethylchloride, η-butylchlorosulfite, and η-amylchlorosulfite, but failed to produce significant amounts of esterification in each case. Mixed formyl, acetyl, propionyl, and butyryl esters of nitrated alginic acids were prepared by progressive replacement of the ...

Crystalline Structures of Alginic Acids
Nature, 1970WE have recently obtained X-ray diffraction photographs from orientated samples of alginic acid preparations in which the ratio of mannuronic acid to guluronic acid was known. The purified unorientated material was supplied by Dr A. Haug, and our results form the basis for structure determinations of polymannuronic acid and polyguluronic acid ...

Enzymatic hydrolysis of alginic acid
Biochimica et Biophysica Acta, 1954Abstract An alginic acid hydrolizing bacterium has been isolated which excretes an enzyme capable of degrading alginic acid into mannuronic acid. A series of intermediary oligomannuronides has been demonstrated by paper chromatography to be present during enzymatic ...

Biocompatibility of mannuronic acid-rich alginates
Biomaterials, 1997Highly purified algin preparations free of adverse contaminants with endotoxins and other mitogens recently became available by a new purification process (Klöck et al., Appl. Microbiol. Biotechnol., 1994, 40, 638-643). An advantage of this purification protocol is that it can be applied to alginates with various ratios of mannuronic acid to guluronic ...

Nature, 1945
THE following is a short account of work completed a matter of two years ago; but publication at the time was forbidden. It was carried out in connexion with the production of rayon from seaweed described by Speakman and Chamberlain1, and for the preparation of the fibres I am indebted to Dr. Chamberlain.

Preparation of composites of laponite with alginate and alginic acid polysaccharides
Polymer International, 2012AbstractPolymer/clay composites have several uses in fields such as engineering, agriculture, ceramics, surface coatings, absorbent materials, pharmaceuticals or catalysis. Polysaccharides, such as alginate and its acid derivatives, are biocompatible and biodegradable polymers, effective in the production of adsorbent systems, for encapsulation and ...

The hydrophilic and acid binding properties of alginates
The American Journal of Digestive Diseases, 19531. Sodium alginate possesses considerable water absorbing and water retaining properties. It is in this respect superior to the natural gums, methylcellulose and carboxymethylcellulose. 2. Sodium alginate and calcium alginate also possess acid binding properties of a similar order as carboxymethylcellulose. 3.
