Immobilization of laccase onto polyethyleneimine grafted chitosan films: Effect of system parameters
(Polymer Soc Korea, 2013)
Chitosan films were prepared via phase-inversion technique. The polyethyleneimine (PEI) was grafted onto chitosan films after activation with various agents, such as epichlorohydrin, genipin and glutaraldehyde. The PEI ...
Covalent immobilization of Candida rugosa lipase on aldehyde functionalized hydrophobic support and the application for synthesis of oleic acid ester
(Taylor & Francis Ltd, 2013)
This study focuses on Candida rugosa lipase (CRL) immobilization by covalent attachment on poly(ethylene terephthalate)-grafted glycidyl methacrylate (PET-g-GMA) fiber. The immobilization yielded a protein loading of ...
Immobilization of laccase on polyacrylamide and polyacrylamide – κ – carragennan-based semiinterpenetrating polymer networks
(Informa Healthcare, 2012)
In this study, laccase enzyme (L) from Agaricus bisporus was immobilized by entrapment into polyacrylamide (PAAm) and semi-interpenetrating polymer networks (semi-IPNs) prepared with either polyacrylamide/kappa-carragennan ...
Production of bioethanol by immobilized Saccharomyces Cerevisiae onto modified sodium alginate gel
(Wiley-Blackwell, 2011)
BACKGROUND: Microbial bioethanol production is an important option in view of the finite global oil reserves. Bioethanol fermentation was carried out using immobilized microorganisms (Saccharomyces cerevisiae, Zymomonas ...
Enzymatic removal of phenol and p-chlorophenol in enzyme reactor: Horseradish peroxidase immobilized on magnetic beads
(Elsevier Science Bv, 2008)
Horseradish peroxidase was immobilized on the magnetic poly(glycidylmethacrylate-co-methylmethacrylate) (poly(GMA-MMA)), via covalent bonding and used for the treatment of phenolic wastewater in continuous systems. For ...
Dye derived and metal incorporated affinity poly(2-hydroxyethyl methacrylate) membranes for use in enzyme immobilization
(John Wiley & Sons Ltd, 1998)
Microporous poly(2-hydroxyethyl methacrylate) (PHEMA) membranes were prepared by W-initiated photopolymerization of HEMA in the presence of an initiator (alpha,alpha'-azobisisobutyronitrile, AIBN). An affinity dye Cibacron ...
Determination of trace metals in geological samples by atomic absorption spectrophotometry after preconcentration by Aspergillus niger immobilized on sepiolite
(Japan Soc Analytical Chem, 1999)
A method for the determination of Cu, Zn, Fe, Ni and Cd in geological samples by flame atomic absorption spectrophotometry (FAAS) after preconcentrating by Aspergillus niger immobilized on sepiolite has been developed. The ...
Determination of iron and nickel by flame atomic absorption spectrophotometry after preconcentration on Saccharomyces cerevisiae immobilized sepiolite
(Elsevier Science Bv, 1998)
Iron and nickel have been preconcentrated on Saccharomyces cerevisiae immobilized sepiolite and determined by flame atomic absorption spectrophotometry (FAAS). Preconcentration studies were conducted by the column method. ...
Immobilization of catalase in poly(isopropylacrylamide-co-hydroxyethylmethacrylate) thermally reversible hydrogels
(John Wiley & Sons Ltd, 1999)
Catalase was entrapped in thermally reversible poly (isopropylacrylamide-co-hydroxyethyl-methacrylate) (pNIPAM/HEMA) copolymer hydrogels. The thermoresponsive hydrogels, in cylindIl-rical geometry, were prepared in an ...
Separation and speciation of Cr(III) and Cr(VI) with Saccharomyces cerevisiae immobilized on sepiolite and determination of both species in water by FAAS
(Elsevier Science Bv, 2000)
A rapid, sensitive and accurate method for the separation, preconcentration and determination of Cr(III) and Cr(VI) in water samples is described. Chromium species can be separated by biosorption on Saccharomyces cerevisiae ...
