Immobilization of antibodies on alginate-chitosan beads.
An anti-hapten IgG was covalently immobilized on glutaraldehyde-activated alginate-chitosan gel beads. The antibody immobilization efficiency was influenced by glutaraldehyde-bead reaction time, IgG concentration and pH. In addition, immobilization conditions such as glutaraldehyde and antibody concentrations influenced antibody hapten binding affinity. The immobilized IgG on the beads was stab...
متن کاملImmobilization of a Plant Lipase from Pachira aquatica in Alginate and Alginate/PVA Beads
This study reports the immobilization of a new lipase isolated from oleaginous seeds of Pachira aquatica, using beads of calcium alginate (Alg) and poly(vinyl alcohol) (PVA). We evaluated the morphology, number of cycles of reuse, optimum temperature, and temperature stability of both immobilization methods compared to the free enzyme. The immobilized enzymes were more stable than the free enzy...
متن کاملAddition 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...
متن کاملImmobilization of Laccase in Alginate-Gelatin Mixed Gel and Decolorization of Synthetic Dyes
Alginate-gelatin mixed gel was applied to immobilized laccase for decolorization of some synthetic dyes including crystal violet. The immobilization procedure was accomplished by adding alginate to a gelatin solution containing the enzyme and the subsequent dropwise addition of the mixture into a stirred CaCl(2) solution. The obtained data showed that both immobilized and free enzymes acted opt...
متن کاملImmobilization of Multi-biocatalysts in Alginate Beads for Cofactor Regeneration and Improved Reusability.
We have recently developed a simple, reusable and coupled whole-cell biocatalytic system with the capability of cofactor regeneration and biocatalyst immobilization for improved production yield and sustained synthesis. Described herewith is the experimental procedure for the development of such a system consisting of two E. coli strains that express functionally complementary enzymes. Together...
