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 ... -
Immobilization of glucose isomerase in surface-modified alginate gel beads
(Wiley, 2008)In this study, glucose isomerase enzyme was entrapped into modified and nonmodified calcium alginate gel beads. Various characteristics of free and immobilized enzymes such as the optimum pH, temperature and dependence of ... -
Immobilization of glucose oxidase and urease in hydrogel matrices
(Scientific Technical Research Council Turkey, 1997)Immobilization of glucose oxidase and urease in hydrogels of 2-hydroxyethyl methacrylae, and N-vinyl pyrrolidone (NVP) was achieved by irradiation (using UV kand gamma-rays). The effect of radiation on entrapment efficiencies, ... -
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 ... -
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 ... -
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 ... -
Immobilization of Saccharomyces cerevisiae on to modified carboxymethylcellulose for production of ethanol
(Springer, 2011)In this work, modified carboxymethylcellulose (CMC) was used as a new support material for production of ethanol. Crosslinked graft copolymers of CMC with N-vinyl-2-pyrrolidone (N-VP) were prepared in different grafting ... -
Immune response to SARS-CoV-2 and mechanisms of immunopathological changes in COVID-19
(WILEY, 2020)As a zoonotic disease that has already spread globally to several million human beings and possibly to domestic and wild animals, eradication of coronavirus disease 2019 (COVID-19) appears practically impossible. There is ... -
