Alcohol determination via covalent enzyme immobilization on magnetic beads
(Elsevier Science Sa, 2008)
Alcohol oxidase was covalently immobilized onto magnetic beads of two different sizes, 75-150 mu m and 50-75 mu m in diameter, fabricated in the presence of glycidylmethacrylate and methylmethacrylate via suspension ...
Covalent immobilization of chloroperoxidase onto magnetic beads: Catalytic properties and stability
(Elsevier, 2008)
Amino groups containing magnetic beads were used in covalent immobilization of the enzyme "chloroperoxidase (CPO)" which is one of a few enzymes that can catalyse the peroxide dependent oxidation of a wide spectrum of ...
Catalase adsorption onto cibacron blue F3GA and Fe(III)derivatized poly(hydroxyethyl methacrylate) membranes and application to a continuous system
(Elsevier Science Bv, 1997)
Poly(2-hydroxyethyl methacrylate) (poly(HEMA)) membranes were prepared by W-initiated photopolymerization of HEMA in the presence of an initiator (a-a'-azobisisobutyronitrile, AIBN). An affinity dye, i.e. Cibacron Blue ...
Covalent immobilization of α-amylase onto pHEMA microspheres: preparation and application to fixed bed reactor
(Elsevier Sci Ltd, 1995)
Microspheres of poly(2-hydroxyethyl methacrylate) with and without cross-linker were prepared by suspension polymerization. As the amount of cross-linker increased, the equilibrium water content, enzyme loading, immobilization ...
Comparison of β-galactosidase immobilization by entrapment in and adsorption on poly(2-hydroxyethylmethacrylate) membranes
(John Wiley & Sons Ltd, 1997)
beta-Galactosidase was immobilized in/on poly(2-hydroxyethyl methacrylate) (pHEMA) membranes by two different methods: adsorption on Cibacron F3GA derivatized pHEMA membranes (pHEMA-CB), and entrapment in the bulk of the ...
Immobilization of glucoamylase onto activated pHEMA/EGDMA microspheres: properties and application to a packed-bed reactor
(Elsevier Science Inc, 1998)
Glucoamylase was covalently immobilized onto pHEMA/EGDMA microspheres of two different sizes: 50-100 mu m and 100-200 mu m in diameter. The activity of the enzyme on smaller microspheres was found to be almost twice that ...
Immobilization of glucoamylase onto spacer-arm attached magnetic poly(methylmethacrylate) microspheres: characterization and application to a continuous flow reactor
(Elsevier Science Bv, 2000)
Magnetic poly(methylmethacrylate) microspheres (MPMMA) were prepared by the solvent evaporation method and a 6-carbon spacer-arm (i.e. hexamethylene diamine, HMDA) was covalently attached by the reaction of carbonyl groups ...
β-galactosidase immobilization into poly(hydroxyethyl methacrylate) membrane and performance in a continuous system
(Wiley-Blackwell, 1999)
The activity of beta-galactosidase immobilized into a poly(2-hydroxyethyl methacrylate) (pHEMA) membrane increased from 1.5 to 10.8 U/g pHEMA upon increase in enzyme loading. The K-m values for the free and the entrapped ...
Epoxy-derived pHEMA membrane for use bioactive macromolecules immobilization: Covalently bound urease in a continuous model system
(John Wiley & Sons Inc, 2000)
Poly(2-hydroxyethylmethacrylate) (pHEMA) membranes were prepared by W-initiated photopolymerization of HEMA in the presence of an initiator (alpha-alpha '-azobisisobutyronitrile, AIBN). The epoxy group, i.e., epichlorohydrin, ...
Immobilization of polyphenol oxidase on carboxymethylcellulose hydrogel beads: preparation and characterization
(John Wiley & Sons Ltd, 2000)
Carboxymethylcellulose (CMC) beads were prepared by a liquid curing method in the presence of trivalent ferric ions, and epicholorohydrin was covalently attached to the CMC beads. Polyphenol oxidase (PPO) was then covalently ...
