The aim of this study was to investigate the effects of Sodiume alginate edible coating with concentrations of 0/25, 1/25, 0/75 and 1/75% (W/V) on chemical changes of dressed Kilka during frozen storage. Prepared samples of Kilka fish have been coated for 1 h with the dipping method. Coated and uncoated samples have been packed in polyethylene dishes with selphon coverage (75 packs of 250 g). C...

background and objective: the opportunistic pathogen pseudomonas aeruginosa secrets a capsule-like polysaccharide called alginate which is important for evasion of host defenses, especially in patients with suppressed immunity. method of alginate determination has an important role in the study of microbial alginate. in this study, a novel method for alginate determination by highperformance li...

Alginate denotes a group of industrially important 1-4-linked biopolymers composed of the C-5-epimers β-D-mannuronic acid (M) and α-L-guluronic acid (G). The polysaccharide is manufactured from brown algae where it constitutes the main structural cell wall polymer. The physical properties of a given alginate molecule, e.g., gel-strength, water-binding capacity, viscosity and biocompatibility, a...

Four hydrophilic polymers in the form of beads - chitosan, alginate, alginate/polyvinyl alcohol (PVA), and chitosan-coated alginate - were used as supports for lipase immobilisation. Hydrogel beads were characterised by bead-size-distribution estimation, surface morphology studies, and polymer interactions assessment. Matrix performances - loading efficiency, immobilisation yield, enzyme activi...

We describe a method for creating alginate hydrogels with adjustable degradation rates that can be used as scaffolds for stem cells. Alginate hydrogels have been widely tested as three-dimensional constructs for cell culture, cell carriers for implantation, and in tissue regeneration applications; however, alginate hydrogel implants can take months to disappear from implantation sites because m...

Mechanically robust alginate-based nanofibrous scaffolds were successfully fabricated by electrospinning method to mimic the natural extracellular matrix structure which benefits development and regeneration of tissues. Alginate-based nanofibres were electrospun from an alginate/poly(vinyl alcohol) (PVA) polyelectrolyte complex. SEM images revealed the spinnability of the complex composite nano...

Objective(s): Pseudomonas aeruginosais a Gram-negative and aerobic rod bacterium that displays mucoid and non-mucoid phenotype. Mucoid strains secrete alginate, which is the main agent of biofilms in chronic P. aeruginosa infections, show high resistance to antibiotics; consequently, the biological disruption of mucoid P. aeruginosa biofilms is an attractive area of study for researchers. Algin...

• Introduction • What are alginate dressings? • How do alginate dressings work? • What are the main indications for alginate dressings? • Are there any side effects of alginate dressings? • Is there any difference between brands? • Is alginate an effective haemostat? • Does zinc make a difference in haemostatic performance? • What is the role of alginate dressings in split skin graft donor site...

An enzymatic in vitro alginate polymerization assay was developed by using 14C-labeled GDP-mannuronic acid as a substrate and subcellular fractions of alginate overproducing Pseudomonas aeruginosa FRD1 as a polymerase source. The highest specific alginate polymerase activity was detected in the envelope fraction, suggesting that cytoplasmic and outer membrane proteins constitute the functional ...
