Alginate Beads Encapsulation Matrix for Urease and Polyethyleneglycol-Urease. Baysal, S. H. Artificial Cells, Blood Substitutes, and Biotechnology, 35(4):457–465, January, 2007. Number: 4
Paper doi abstract bibtex Urease was immobilized activated PEG-5000 and encapsulated urease and PEG modified urease within alginate beads. Encapsulated urease and PEGurease were thoroughly characterized for pH, temperature and stabilities and these properties were compared with free and PEG modified enzyme. A 34 and 57% mass and 19.3 and 43% activity yield of urease and PEG-urease resulted fol lowing encapsulation. The average diameter for the beads was found to be 2.5 mm for urease bead and 1.8 mm for PEG-urease bead. The stabilities of PEG-urease beads at pH 6.0 were higher than those of urease beads. PEG-urease beads retained 70% of initial activity after reusing seven times at pH 6.0. Also time dependency of substrate conversion was determined for enzyme beads.
