Biosorption of Reactive Blue 4 dye by native and treated fungus Phanerocheate chrysosporium: Batch and continuous flow system studies
Bayramoglu, Gulay; Celik, Gokce; Arica, M. Yakup (Elsevier, 2006)The native and treated fungal biomass of Phanerocheate chrysosporium was used for the biosorption of a textile dye (i.e., Reactive Blue 4). In the batch system, the biosorption equilibrium time was about 4 h and the maximum ... -
Effect of spacer-arm and Cu(II) ions on performance of L-histidine immobilized on poly(GMA/MMA) beads as an affinity ligand for separation and purification of IgG
Bayramoglu, Gulay; Senel, Aysegul Ulku; Arica, M. Yakup (Elsevier, 2006)In this study, the beads were prepared from glycidiyl methacrylate (GMA) and methyl methacrylate (MMA) via suspension polymerization and, the used beads fractions were between 75 and 150 mu m. The epoxy groups of the beads ... -
Immobilization of beta-galactosidase onto magnetic poly(GMA-MMA) beads for hydrolysis of lactose in bed reactor
Bayramoglu, Gulay; Tunali, Yagmur; Arica, M. Yakup (Elsevier, 2007)In the present study, novel magnetic beads were prepared from glycidylmethacrylate and methylmethacrylate via suspension polymerization in the presence of a cross-linker (i.e. ethylenedimethylmethacrylate). The magnetic ... -
Immunoglobulin G adsorption behavior of L-histidine ligand attached and Lewis metal ions chelated affinity membranes
Bayramoglu, Gulay; Celik, Gokce; Arica, M. Yakup (Elsevier Science Bv, 2006)Immobilized metal affinity membranes were prepared by chelating Cu(II) and Fe(III) ions on poly(2-hydroxyethyl methacrylate-glycidyl methacrylate), poly(HEMA-GMA) membranes using L-histidine as a chelating ligand. To achieve ... -
Removal of Cd(II), Hg(II), and MID ions from aqueous solution using p(HEMA/Chitosan) membranes
Bayramoglu, Gulay; Arica, M. Yakup; Bektas, Sema (Wiley, 2007)An interpenetration network (IPN) was synthesized from 2-hydroxyethyl methacrylate (HEMA) and chitosan, p(HEMA/chitosan) via UV-initiated photo-polymerization. The selectivity to different heavy metal ions viz Cd(II), ... -
Reversible immobilization of glucose oxidase on polyaniline grafted polyacrylonitrile conductive composite membrane
Bayramoglu, Gulay; Metin, Ayseguel Ue; Altintas, Begum; Arica, M. Yakup (Elsevier Sci Ltd, 2010)Polyacrylonitrile membrane surfaces were modified with chemical polymerization of conductive polyaniline. The effect of aniline concentration on the grafting efficiency was investigated As the amount of grafted PANI increased ... -
Studies on accumulation of uranium by fungus Lentinus sajor-caju
Bayramoglu, Gulay; Celik, Gokce; Arica, M. Yakup (Elsevier, 2006)The untreated, heat- and alkali-treated Lentinus sajor-caju mycelia were used for the recovery of uranium from aqueous solutions. The effect of pH, temperature, initial concentration of UO22+, ions and contact time parameters ...
