Degradation of Calcium Gels of Alginate and Periodate Oxidised Alginate [PDF]

, 2016
The extracellular matrix (ECM) functions as a structural scaffold for cells and controls cellular function through cell-matrix interactions. These interactions are required by most cells in order to maintain viable and promote proliferation. Therefore, an appropriate synthetic extracellular matrix is necessary for tissue engineering applications ...

Effect of γ-Irradiation on Degradation of Alginate

Journal of Agricultural and Food Chemistry, 2003
The aqueous solution of alginate was irradiated by 60Co gamma-rays in the dose range of 10-500 kGy. To assess the effect of irradiation on the degradation of alginate, the irradiation-induced changes in the viscosity, molecular weight, color, monomer composition, and sequence were measured.

Kinetic of thermal degradation of alginate-zeolite composites [PDF]

Zaštita Materijala, 2016
In this work, natural and Fe(III)-modified zeolte were tested as additives for alginate in order to improve its thermal and pyrolytic properties. For that purpose the natural zeolite (NZA) and Fe(III)- modified zeolite coated with alginate (FeA) were ...

Alginate Degradation: Insights Obtained through Characterization of a Thermophilic Exolytic Alginate Lyase. [PDF]

Appl Environ Microbiol, 2021
The potential markets for seaweed-derived products and seaweed processing technologies are growing, yet commercial enzyme cocktails for complete conversion of seaweed to fermentable sugars are not available. Such an enzyme cocktail would require the catalytic properties of a variety of different enzymes, where fucoidanases, laminarinases, and ...

Encapsulation of fibroblasts causes accelerated alginate hydrogel degradation

Acta Biomaterialia, 2010
Calcium-alginate hydrogel has been widely studied as a material for cell encapsulation for tissue engineering. At present, the effect that cells have on the degradation of alginate hydrogel is largely unknown. We have shown that fibroblasts encapsulated at a density of 7.5 × 105 cells ml−1 in both 2% and 5% w/v alginate remain viable for at least 60 ...

Genome Analysis of a Polysaccharide-Degrading Bacterium Microbulbifer sp. HZ11 and Degradation of Alginate

Marine Drugs
Marine bacteria are crucial sources of alginate lyases, which play an essential role in alginate oligosaccharide (AOS) production. This study reports the biochemical characteristics of a new species of the Microbulbifer genus, Microbulbifer sp. HZ11. The

An alginate hydrogel matrix for the localised delivery of a fibroblast/ keratinocyte co-culture to expedite wound healing [PDF]

, 2010
There is a clinical need for effective alternative skin replacements to autografts, allografts and xenografts. In this thesis a bi-layer skin graft was developed by encapsulation of fibroblasts in calcium-alginate hydrogel and culture of keratinocytes on

In vivo degradation of alginate in the presence and in the absence of resistant starch

Food Chemistry, 2015
This study evaluated the intestinal degradability of alginate during 74 days intake in pigs as models for humans. Diets contained pregelatinized starch, retrograded starch, alginate, or a mix of retrograded starch and alginate. Faeces were collected on day 1, 3, 7, 14, 39 and 74. Clear trends in intestinal alginate degradation were observed.
