Survival of human islets in microbeads containing high guluronic acid alginate crosslinked with Ca2+and Ba2+

Study of fresh microencapsulated islets with polylysine-alginate in xenografts.

Impact of hydrolysis conditions on the detection of mannuronic to guluronic acid ratio in alginate and its derivatives.

Alginate is a linear and acidic polysaccharide, composed of (1 → 4) linked β-D-mannuronic acid (ManA) and α-L-guluronic acid (GulA). The ratio of ManA to GulA (M/G) is one of the most important factors for the application of alginate and its derivatives in various areas. In this work, a robust and accurate method was developed to analyze M/G using high-performance anion-exchange chromatography ...

Bioactive Films Containing Alginate-Pectin Composite Microbeads with Lactococcus lactis subsp. lactis: Physicochemical Characterization and Antilisterial Activity

Novel bioactive films were developed from the incorporation of Lactococcus lactis into polysaccharide films. Two different biopolymers were tested: cellulose derivative (hydroxylpropylmethylcellulose (HPMC)) and corn starch. Lactic acid bacteria (LAB) free or previously encapsulated in alginate-pectin composite hydrogel microbeads were added directly to the film forming solution and films were ...

Survival of alginate-prebiotic microencapsulated Lactobacillus acidophilus in mayonnaise sauce

Background: Nowadays, Microencapsulation of probiotic bacteria is the newest method for increasing the survival ability of probiotics in Food products. The Lactobacillus acidophilus as a probiotic bacterium has more beneficial effects and the low survival of this bacterium under food processing conditions and adverse environment have been studied by many researchers. OBJECTIVES: In this study, ...

Micro-environmentally Restricted Yeast Cell Growth within Ca-alginate Microbeads

Micro-environmental restriction effects to yeast cell growth obtained within Ca-alginate microbeads are considered. It is complex phenomenon influenced by: (1) relaxation of expanded polymer network around the cellular clusters, (2) forces generated by cell growth inside the beads and (3) interactions between solvent, network parts and cells. The resulting effects are measured experimentally by...
