Cr(VI) biosorption from aqueous solutions using free and immobilized biomass of Lentinus sajor-caju: preparation and kinetic characterization
(Elsevier Science Bv, 2005)
The potential use of the free and immobilized mycelia (in carboxymethylcellulose (CMC)) of Lentinus sajor-caju to remove hexavalent form of chromium ions, Cr(VI), from aqueous solutions was evaluated using CMC bead as a ...
Purification of lysozyme from egg white by Reactive Blue 4 and Reactive Red 120 dye-ligands immobilised composite membranes
(Elsevier Sci Ltd, 2005)
A composite membrane was synthesized from 2-hydroxyethylmethacryl ate (HEMA) and chitosan (pHEMA/chitosan) via UV initiated photo-polymerisation. Reactive Blue 4 (Blue-4) and Reactive Red 120 (Red-120) were immobilised ...
Modification of surface properties of Lentinus sajor-caju mycelia by physical and chemical methods: evaluation of their Cr6+ removal efficiencies from aqueous medium
(Elsevier, 2005)
The hexavalent chromium biosorption onto untreated and heat-, acid- and alkali-treated Lentinus sajor-caju mycelia. were studied from aqueous solutions. The particles sizes of the fungal mycelia ranged from 100 to 200 mu ...
Separation and purification of lysozyme by Reactive Green 19 immobilised membrane affinity chromatography
(Elsevier Sci Ltd, 2005)
A poly(hydroxyethylmethacrylate)/chitosan (pHEMA-chitosan) composite membrane was prepared by UV-initiated photopolyrnerisation. A dye ligand (i.e. Reactive Green 19; RG 19) was immobilised onto the membrane. The water ...
Polyethylenimine-grafted and HSA-immobilized poly(GMA-MMA) aff inity adsorbents for bilirubin removal
(Wiley-Blackwell, 2005)
The epoxy-group-containing microspheres from cross-linked glycidyl methacrylate and methyl methacrylate, poly(GMA-MMA), were prepared by suspension polymerisation. The epoxy groups of the poly(GMA-MMA) microspheres were ...
Invertase reversibly immobilized onto polyethylenimine-grafted poly(GMA-MMA) beads for sucrose hydrolysis
(Elsevier Science Bv, 2006)
The epoxy group containing poly(glycidyl methacrylate-co-methyl methacrylate) poly(GMA-MMA) beads were prepared by suspension polymerisation and the beads surface were grafted with polyethylenimine (PEI). The PEI-grafted ...
Human serum albumin adsorption on poly[(glycidyl methacrylate)-co-(methyl methacrylate)] beads modified with a spacer-arm-attached L-histidine ligand
(Wiley, 2006)
Poly(GMA/MMA) beads were synthesized from glycidyl methacrylate (GMA) and methyl methacrylate (MMA) in the presence of a cross-linker (i.e. ethyleneglycol dimethacrylate) (EGDMA) via suspension polymerization. The epoxy ...
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 ...
In-vitro studies of enteric coated diclofenac sodium-carboxymethylcellulose microspheres
(Taylor & Francis Ltd, 1996)
Microspheres containing diclofenac sodium (DS) were prepared using carboxymethylcellulose (CMC) as the main support material (1.0, 2.0, 3.0% (w/v)) and aluminium chloride as the crosslinker. Drug to polymer ratios of 1:1, ...
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 ...
