the alginate was extracted with six different methods from iran south seacoast algae, sargassum sp, and the percentage yield of alginate was determined. we divided our methods to two groups including acidic extraction and non-acidic. in acidic methods, hcl and h 2 so 4 were used as a detergent in extraction process and cacl 2 was exerted in non-acidic treatments. all treatments compared with ea...

BACKGROUND/PURPOSE To investigate the effect of nanosilver particles in solution stabilized in a matrix of sodium alginate on the growth and development of pathogenic bacteria such as Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Proteus vulgaris, Enterobacter cloacae, the antibiotic-resistant strain of Pseudomonas aeruginosa, the yeast-like fungus Candida albicans, and the lu...

Water-in-Water (W/W) emulsions were prepared in aqueous mixtures of an anionic polyelectrolyte (sodium alginate, NaAlg), with a globular protein (bovine serum albumin, BSA). This combination showed phase separation at two different intervals pH, and their behavior was studied. BSA-in-alginate obtained dropped into Ca2+, Fe3+ or chitosan solutions, forming capsules diameters around 2–4 mm, by io...

This research aimed at investigating the cryoprotectant action of glucose and lactose on strains of Malassezia spp. and zygomycetes immobilised in sodium alginate. Twelve strains of Malassezia spp. (nine M. furfur, two M. globosa and one M. sympodialis) and 12 zygomycetes (five Rhizopus oryzae and seven Mucor hiemales) were immobilised in sodium alginate, within plastic beads, maintained in app...

The total haemocyte count (THC), phenoloxidase (PO) activity, respiratory bursts (release of superoxide anions), and superoxide dismutase (SOD) activity, as well as expressions of beta-1,3-glucan-binding protein (betaGBP), prophenoloxidase (proPO), peroxinectin (PE), cytosolic SOD (cyt-SOD), penaeidin-5 (PA-5), and a single whey acidic protein (WAP) domain protein (SWDP) gene were determined in...

in the present study, floating drug delivery beads (fdds) were prepared with sodium alginate/ starch blend as a matrix, sodium hydrogen carbonate as a pore forming agent, methyl cellulose as a binder and barium chloride solution as a hardening agent. in order to prepare the beads with different porosity and morphology the ratio between pore forming agent to polymer blend and ratio of the consti...

the present study describes the encapsulation of protocorm of cymbidium bicolor lindl. from 60 days-old in seed cultures for short- term conservation and propagation. various concentrations and combinations of gelling matrix (sodium alginate) and complexing agents (calcium chloride) were tested to prepare uniform beads. the ideal beads were ob- tained through a combination of 3% sodium alginate...

the purpose of the research was to formulate microspheres of acyclovir (acv) using mucoadhesive polymers, sodium alginate and chitosan. calcium chloride was used as the ionotropic gelling agent. sodium alginate was crosslinked by calcium chloride leading to a slower release of the drug. chitosan which is a cationic polymer interacted with sodium alginate, an anionic polymer, to form an interpol...
