Non-Condensing Calcium Alginate Microspheres for
The main objective of the study was to design a non-condensing polymeric microspherebased gene delivery system for targeting macrophages. An external gelation technique was used to prepare plasmid DNA-encapsulated calcium alginate microspheres. The microspheres were characterized for particle size, surface charge, surface morphology, and DNA loading efficiency. Stability of encapsulated DNA was...
متن کاملRemoval of Phenols with Encapsulated Horseradish Peroxidase in Calcium Alginate
Horseradish peroxidase was encapsulated in calcium alginate for the purpose of phenol removal. Considering enzyme encapsulation efficiency, retention activity and enzyme leakage of the capsules, the best gelation condition was found to be 1 % w/v of sodium alginate solution and 5.5 % w/v of calcium chloride hexahydrate. Upon immobilization, pH profile of enzyme activity changes as it shows ...
متن کاملRole of alginate lyase in cell detachment of Pseudomonas aeruginosa.
The exopolysaccharide alginate of Pseudomonas aeruginosa was shown to be important in determining the degree of cell detachment from an agar surface. Nonmucoid strain 8822 gave rise to 50-fold more sloughed cells than mucoid strains 8821 and 8830. Alginate anchors the bacteria to the agar surface, thereby influencing the extent of detachment. The role of the P. aeruginosa alginate lyase in the ...
متن کاملThe drug release profile from calcium-induced alginate gel beads coated with an alginate hydrolysate.
Calcium-induced alginate gel bead (Alg-Ca) coated with an alginate hydrolysate (Alg), e.g. the guluronic acid block (GB) was prepared and the model drug, hydrocortisone release profiles were investigated under simulated gastrointestinal conditions. Their molecular weights were one sixth or one tenth that of Alg and the diffraction patterns of the hydrolysates resembled that of Alg. The drug rel...
