Abstract
In this study, immobilization of invertase enzyme was performed on a previously synthesized and characterized poly(N-vinylpyrrolidone-co-butylacrylate-co-N hydroxymethylacrylamide) terpolymer membranes by covalent bonding method. Glutaraldehyde(GA) was used as the crosslinker and Bovine Serum Albumin(BSA) was used as the binding agent. Optimum pH, temperature, amount of polymer, substrate concentration, amount of BSA and amount of GA values were determined for both free and immobilized enzyme. Optimum pH and temperature values were found as pH = 5.0, T = 55 °C, pH = 7.0 and T = 80 °C for free and immobilized enzyme, respectively. In particular, the optimum temperature of 80 °C for the immobilized enzyme provides its potential to be used commercially. The kinetic parameters of the free enzyme and the immobilized enzyme were determined using the well known Lineweaver-Burk method. The Vmax values for free (13.4 μM/min) and immobilized enzyme (12.2 μM/min) were found as close to each other, while the Km value of the immobilized enzyme (8.33 mM) was much lower than that of the free enzyme (29.41 mM). In reuse studies conducted with peach and orange juices, it was determined that the immobilized enzyme retained approximately 90% of its activity even after 30 reuses within 1 month.

Abstract
Poly(maleic anhydride-alt-hexen-1)(poly(MA-alt-H-1)) has been synthesized by radical polymerization and characterized by DSC, FT-IR, acid number determination, viscometric and NMR methods. Data showed that the co-polymer is an alternating co-polymer whose composition does not depend on the monomer feed composition. Invertase was immobilized onto a poly(MA-alt-H-1) membrane via glutaraldehyde and bovine serum albumin. The Km value of poly(MA-alt-H-1)-invertase was approximately 4.4-fold higher than the free enzyme, indicating decreased affinity by the invertase for its substrate (sucrose), whereas Vmax was lower for the immobilized invertase. Immobilization improved the pH stability of the enzyme, as well as its temperature stability. Immobilized samples obtained were stable and could be used many times over a period of 2 months without considerable activity loss.

Abstract
Biosensor construction and characterization studies of poly(acrylic acid) (PAA) and poly(1-vinyl imidazole) (PVI) complex systems have been carried out. The biosensors were prepared by mixing PAA with PVI at several stoichiometric ratios, x (molar ratio of the monomer repeat units). The enzyme, invertase, was entrapped in the PAA/PVA interpenetrating polymer networks during complexation. Modifications were made on the PAA/PVI conducting polymer electrolyte matrixes to improve the stability and performance of the polymer electrolyte-based enzyme biosensor. The maximum reaction rate (V(max)) and Michaelis-Menten constant (K(m)) were investigated for the immobilized invertase. The temperature and pH optimization, operational stability, and shelf life of the polymer electrolyte biosensor were also examined.

Glucose oxidase was immobilized in conducting copolymers of three different types of poly(methyl methacrylate-co-thienyl methacrylate). Immobilization of enzyme was carried out by the entrapment in conducting polymers during electrochemical polymerization of pyrrole on the copolymer electrodes. Maximum reaction rate, Michaelis-Menten constants, temperature, pH and operational stabilities were determined for immobilized enzyme. The amount of glucose in orange juices of Turkey was investigated by using enzyme electrodes.

Abstract
Immobilization of invertase in conducting copolymer matrices of 3-methylthienyl methacrylate with pyrrole and thiophene was achieved by constant potential electrolysis using sodium dodecyl sulfate (SDS) as the supporting electrolyte. Polythiophene (PTh) was also used in entrapment process for comparison. Kinetic parameters, Michaelis-Menten constant, K(m), and the maximum reaction rate, V(max), were investigated. Operational stability and temperature optimization of the enzyme electrodes were also examined.

Abstract
The possibility of using thermostable inulinases from Aspergillus ficuum in place of invertase for sucrose hydrolysis was explored. The commercial inulinases preparation was immobilized onto porous glass beads by covalent coupling using activation by a silane reagent and glutaraldehyde before adding the enzyme. The immobilization steps were optimized resulting in a support with 5,440 IU/g of support (sucrose hydrolysis) that is 77% of the activity of the free enzyme. Enzymatic properties of the immobilized inulinases were similar to those of the free enzymes with optimum pH near pH 5.0. However, temperature where the activity was maximal was shifted of 10 degrees C due to better thermal stability after immobilization with similar activation energies. The curve of the effect of sucrose concentration on activity was bi-phasic. The first part, for sucrose concentrations lower than 0.3 M, followed Michaelis-Menten kinetics with apparent K(M) and Vm only slightly affected by immobilization. Substrate inhibition was observed at values from 0.3 to 2 M sucrose. Complete sucrose hydrolysis was obtained for batch reactors with 0.3 and 1 M sucrose solutions. In continuous packed-bed reactor 100% (for 0.3 M sucrose), 90% (1 M sucrose) or 80% sucrose conversion were observed at space velocities of 0.06-0.25 h(-1). The operational half-life of the immobilized inulinases at 50 degrees C with 2 M sucrose was 350 days.
