Immobilization of glucoamylase on the plain and on the spacer arm-attached poly(HEMA-EGDMA) microspheres
(John Wiley & Sons Inc, 2001)
Immobilization glucoamylase onto plain and a six-carbon spacer arm (i.e., hexamethylene diamine, HMDA) attached poly(2-hydroxyethylmethacrylate-ethylen col dimethacrylate) [poly(HEMA-EGDMA] microspheres was studied. The ...
Reversible immobilization of lipase on phenylalanine containing hydrogel membranes
(Elsevier Sci Ltd, 2001)
Poly(2-hydroxyethylmethacrylate-co-methacrylamidophenlyalanine) poly(HEMA-MAPA) membranes were prepared by UV-initiated photopolymerization of HEMA and MAPA. Lipase immobilization onto these membranes from aqueous solutions ...
Poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) reactive membrane utilised for cholesterol oxidase immobilisation
(John Wiley & Sons Ltd, 2002)
Poly(2-hydroxyethyl methacrylate-co-glycidyl methacrylate) p(HEMA-GMA) membrane was prepared by UV-initiated photopolymerisation of 2-hydroxyethyl methacrylate (HEMA) and glycidyl methacrylate (GMA) in the presence of an ...
Application of NaOH treated Polyporus versicolor for removal of divalent ions of Group IIB elements from synthetic wastewater
(Elsevier Sci Ltd, 2002)
Three different forms of Polyporus versicolor, i.e. alkali-pretreated, heat-inactivated and active, were used for the removal of the divalent ions of Group JIB elements from aquatic systems. The biosorption of Zn(II), ...
Membrane with incorporated hydrophobic ligand for hydrophobic interaction with proteins: application to lipase adsorption
(Wiley, 2002)
In this study, phenylalanine as a hydrophobic ligand was covalently attached on a comonomer, methacryloyl chloride. Then, poly(2-hydroxyethyl methacrylate-co-methacrylamido-phenylalanine), poly(HEMA/MAPA), membranes were ...
Adsorption of serum albumin and gamma-globulin from single and binary mixture and characterization of pHEMA-based affinity membrane surface by contact angle measurements
(Elsevier Science Bv, 2005)
In this study, an affinity membrane was synthesized using 2-hydroxyethylmethacrylate (HEMA) via UV-initiated photopolymerization. A dye-ligand (i.e., Procion Red HE-3B; Red-120) was covalently immobilized onto membrane. ...
Hydrolysis of sucrose by invertase immobilized onto novel magnetic polyvinylalcohol microspheres
(Elsevier Sci Ltd, 2001)
The magnetic polyvinylalcohol (PVAL) microspheres were prepared by crosslinking glutaraldehyde. 1,1 ' -Carbonyldiimidazole (CDI), a carbonylating agent was used for the activation of hydroxyl groups of polyvinylalcohol, ...
Fibronectin purification from human plasma in a packed-bed column system with gelatin immobilized PHEMA microspheres
(Vsp Bv, 2001)
Bioaffinity chromatography has a unique and powerful role that is used as a purification tool in the production of therapeutic plasma protein derivatives. In this study, a bioaffinity-ligand, i.e. gelatin, was covalently ...
Biosorption of cadmium(II), lead(II) and copper(II) with the filamentous fungus Phanerochaete chrysosporium
(Elsevier Sci Ltd, 2001)
The biosorption from artificial wastewaters of heavy metals (Cd(II), Pb(II) and Cu(II)) onto the dry fungal biomass of Phanerochaete chryosporium was studied in the concentration range of 5-500 mg 1(-1). The maximum ...
Procion Brown MX-5BR attached and Lewis metals ion-immobilized poly(hydroxyethyl methacrylate)/chitosan IPNs membranes: Their lysozyme adsorption equilibria and kinetics characterization
(Pergamon-Elsevier Science Ltd, 2002)
Interpenetration networks (IPNs) in membrane form were synthesized from 2-hydroxyethyl methacrylate (HEMA) and chitosan (pHEMA/chitosan) via UV-initiated photo-polymerization in the presence of an initiator alpha, ...
