Alginate Beads Containing Lactase: Stability and Microstructure

Addition of Fillers to Sodium Alginate Solution Improves Stability and Immobilization Capacity of the Resulting Calcium Alginate Beads

Background: Although advantages of immobilization of cells through entrapment in calcium alginate gel beads have already been demonstrated, nevertheless, instability of the beads and the mass transfer limitations remain as the major challenges.Objective: The objective of the present study was to increase the stability, porosity (reduce mass transfer limit...

Gel microstructure regulates proliferation and differentiation of MC3T3-E1 cells encapsulated in alginate beads.

For cell transplantation into damaged tissues, viable cells must be delivered to the defect site in a suitable carrier. However, the hypoxic and nutrient-limited environment in the carrier can induce massive cell death. The aims of this study were to increase the viability and regulate the behavior of osteoprogenitor cells encapsulated in alginate hydrogels through control of the gel microstruc...

preparation and comparision of alginate beads containing lactobacillus acidophilus by cacl2 and alcl3 as crosslinker

Preparation and Characterization of Alginate and Psyllium Beads Containing Lactobacillus acidophilus

This paper describes preparation and characterization of beads of alginate and psyllium containing probiotic bacteria of Lactobacillus acidophilus DMSZ20079. Twelve different formulations containing alginate (ALG) and alginate-psyllium (ALG-PSL) were prepared using extrusion technique. The prepared beads were characterized in terms of size, morphology and surface properties, encapsulation effic...

Characteristics of vitamin C immobilized particles and sodium alginate beads containing immobilized particles.

This paper reports the properties of vitamin C encapsulated sodium alginate beads prepared by an alternative approach. The alternative encapsulation process mainly involves immobilization of vitamin C in hydrated zinc oxide layers and encapsulation of prepared immobilized particles in sodium alginate bead. The immobilization of vitamin C in hydrated zinc oxide layers was achieved by a coprecipi...
