Synthesis and Characterisation of Biocompatible Polymer-Conjugated Magnetic Beads for Enhancement Stability of Urease
(Springer, 2016)
We reported natural polymer-conjugated magnetic featured urease systems for removal of urea effectively. The optimum temperature (20-60 A degrees C), optimum pH (3.0-10.0), kinetic parameters, thermal stability (4-70 A ...
A new bioremediation method for removal of wastewater containing oils with high oleic acid composition:Acinetobacter haemolyticuslipase immobilized on eggshell membrane with improved stabilities
(Royal Society of Chemistry, 2021)
As a result of the increasing demand for edible oils, which are an important part of human nutrition, in recent years, serious environmental problems may arise both during the production and after consumption of these oils. ...
Immobilization of pancreatic lipase on chitin and chitosan
(Taylor & Francis Inc, 2006)
In this study, porcine pancreatic lipase (EC 3.1.1.3) was immobilized on chitin and chitosan by adsorption and subsequent crosslinking with glutaraldehyde, which was added before (conjugation) or after (crosslinking) washing ...
Antibiofilm and anti-quorum sensing activities of polyethylene imine coated magnetite and nickel ferrite nanoparticles
(Springer Science and Business Media Deutschland GmbH, 2020)
This study was aimed at synthesizing polyethyleneimine-coated magnetic nanoparticles and evaluating their effect on pathogenic bacteria. Polyethyleneimine-coated magnetite (PEIMnF) and nickel ferrite (PEINF) nanoparticles ...
Synthesis and characterization of electrospun PVA/Zn2+ metal composite nanofibers for lipase immobilization with effective thermal, pH stabilities and reusability
(Elsevier Science Bv, 2019)
Polyvinyl alcohol (PVA)/Zn2+ electrospun nanofibers that were a kind of polymer/ionic metal composite was successfully embedded in the hybrid fibers for the first time in the literature, due to chemical interactions between ...
Urease immobilized electrospun PVA/chitosan nanofibers with improved stability and reusability characteristics: an application for removal of urea from artificial blood serum
(Taylor & Francis Inc, 2020)
Electrospun polyvinyl alcohol (PVA)/Chitosan nanofibers were successfully prepared and were used as carriers for the first time in urease immobilization. Also, urease immobilized electrospun PVA/Chitosan nanofibers were ...
A selective molecularly imprinted polymer for immobilization of acetylcholinesterase (AChE): an active enzyme targeted and efficient method
(Wiley-Blackwell, 2015)
In the present study, we immobilized acetylcholinesterase (AChE) enzyme onto acetylcholine removed imprinted polymer and acetylcholine containing polymer. First, the polymers were produced with acetylcholine, substrate of ...
Selective extraction of iron(III) from aqueous nitrate solution in the presence of cobalt(II), copper(II) and nickel(II) ions using BiS(Delta(2)-2-imidazolinyl)-5,5 '-dioxime
(Japan Soc Analytical Chemistry, 2004)
The feasibility of using bis(Delta(2)-2-imidazolinyl)-5,5'-dioxime (H2L) for the selective extraction of iron(III) from aqueous solutions was investigated by employing an solvent-extraction technique. The extraction of ...
DEVELOPMENT OF A NEW BIOSENSOR FOR DETERMINATION OF CATALASE ACTIVITY
(Taylor & Francis Inc, 2014)
Catalase is one of the major antioxidant enzymes that catalyzes the hydrolysis of H2O2. The aim of this study was to suggest a new method for the assay of catalase activity. For this purpose, an amperometric biosensor based ...
beta-cyclodextrin based electrospun nanofibers for arginase immobilization and its application in the production of L-ornithine
(SPRINGER, 2022)
Electrospinning is the most effective and efficient method for nanofiber production. In this study, polyvinyl alcohol (PVA)/beta-cyclodextrin (beta-CD) and PVA/beta-CD/Mn2+ electrospun nanofibers were synthesized for use ...
