Alginates pertain to organic polysaccharides that have been extensively used in food- and medicine-related industries. The present study obtained alginates from an alginate overproducing Pseudomonas aeruginosa PAO1 mutant by screening transposon mutagenesis libraries. The interaction between bacterial and seaweed alginates and gut microbiota were further studied by using an in vitro batch ferme...

Alginate is an important polysaccharide used widely in the food, textile, printing and pharmaceutical industries for its viscosifying, and gelling properties. All commercially produced alginates are isolated from farmed brown seaweeds. These algal alginates suffer from heterogeneity in composition and material properties. Here, we will discuss alginates produced by bacteria; the molecular mecha...

• 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...

Alginate-based microcapsules are used for immunoisolation of cells to release therapeutics on a minute-to-minute basis. Unfortunately, alginate-based microcapsules are suffering from varying degrees of success, which is usually attributed to differences in tissue responses. This results in failure of the therapeutic cells. In the present study we show that commercial, crude alginates may contai...

One of the main challenges in tissue engineering and regenerative medicine is the ability tomaintain optimal cell function and survival post-transplantation and to protect the transplantedcells from immune responses and rejection in the host-tissue microenvironment. Biomaterialssuch as alginates can be utilised for immunoisolation, while they may also provide structuralsupport t...

Alginates are natural polysaccharides that are extracted from brown seaweeds and widely used for their rheological properties. The central step in the extraction protocol used in the alginate industry is the alkaline extraction, which requires several hours. In this study, a significant decrease in alginate dynamic viscosity was observed after 2 h of alkaline treatment. Intrinsic viscosity and ...

Alginates are polysaccharides that are widely used in relation to their ability to form gels. Recently we reported that alginates may also form gels with chitosan oligomers as crosslinkers (Khong, Aarstad, Skjåk-Bræk, Draget, & Vårum, 2013). The purpose of the present study was to characterize alginate gels crosslinked with calcium and chitosan oligomers. Using two different alginates of simila...

Introduction: In the prevention and treatment of obesity dietary regiments plays a major role. Recently the benefits of different food supplements are pointed out. The aim of our study was to examine the effect of alginates on the weight loss and body mass index (BMI), and some metabolic parameters in adults and rodents. Materials and methods: The first study represented a clinical study. A tot...

Even today when digital impression techniques are gaining in importance, conventional impressions are still standard in daily practice. The decision for a certain impression material depends primarily on the intended treatment and purpose of the model to be created. Alginates have a large and important share of the dental impression market although for decades more technically sophisticated and...
