Glucose oxidase of Phanerochaete chrysosporium
1988Publisher Summary Glucose oxidase catalyzes the oxidation of D-glucose to δ-D-gluconolactone and H 2 O 2 in the presence of molecular oxygen. In a subsequent step δ -D-gluconolactone is nonenzymatically hydrolyzed to D-gluconic acid. This enzyme has been demonstrated in various Aspergillus and Penicillium species and has recently been purified ...

Immunologic Properties of Glucose Oxidase
The Journal of Immunology, 1970Abstract Glucose oxidase, an anzyme obtained from Aspergillus niger, is a potent antigen. Guinea pigs and rabbits immunized with this antigen in complete Freund's adjuvant produced high serum concentrations of precipitating antibody. In addition, heat-inactivated enzyme and apoenzyme can be used to detect cellular immunity in the guinea ...

Laccase/glucose oxidase electrode for determination of glucose
Analytica Chimica Acta, 1986Abstract The electrode involves a layer of co-immobilized glucose oxidase and laccase in a gelatin membrane placed over a modified oxygen electrode. Hexacyanoferrate(III) is added to the samples to oxidize reductive interferents such as ascorbic acid, and the hexacyanoferrate(II) formed is re-oxidized by a laccase-catalyzed reaction. Ascorbic acid is

Reduction of Glucose Content in Potatoes with Glucose Oxidase [PDF]
Journal of Food Science, 1989 ABSTRACTTwo commercial glucose oxidase preparations, DeeO 1500 and Fermcozyme CBB‐750, were investigated for their activities and use in decreasing glucose levels in Norland and Shepody potatoes. When DeeO was added at 0.01% by weight of peeled potatoes, glucose of potato extracts of both cultivars was decreased by about 22% when the extracts were ...

Calorimetric Glucose Determination by Glucose Oxidase —Methylene Blue
Acta Biotechnologica, 1982AbstractThe reaction between glucose and methylene blue, catalyzed by glucose oxidase (GOD)was analysed calorimetrically.The amount of heat produced under saturating methylene blue concentrations ( > 10−2 mol/1)was measured with glucose concentration and time as parameters (kinetic procedure) Kinetic constants (pseudo one substrate kinetics) were ...

Studies on conditions for the polarographic determination of glucose with glucose oxidase
Clinica Chimica Acta, 1972Abstract Results are presented on the effect of several variables on a method for the determination of glucose using a polarograph with a Clark-type O 2 electrode and glucose oxidase. Glucose concentration [ G ] was proportional to the rate of O 2 consumption |− Δ O 2 / Δt | in the 5–800 μg/ml range.

Notes on the Glucose Oxidase Method
Scandinavian Journal of Clinical and Laboratory Investigation, 1967This is a report of some methodological studies on the enzymatic determination of blood sugar, in particular concerning the composition of the enzyme mixture, the non-specific oxidation, the precipitation media, the effect of added heparin, fluoride, and benzoic acid, and the glutathione problem.

[32] The glucose oxidase—catalase system
1976Publisher Summary This chapter discusses the immobilization and assay procedure of the glucose oxidase–catalase system. Glucose oxidase is a glycoprotein having a molecular weight of approximately 150,000–180,0001; it contains 2 moles of flavin adenine dinucleotide per mole of enzyme and 11–16% carbohydrates.

The characterization of liposomal glucose oxidase electrodes for the measurement of glucose
Biosensors and Bioelectronics, 1995Many biosensors have been described for the measurement of glucose in order to monitor diabetic patients. Glucose oxidase has been used commonly in the construction of glucose sensors but the performance of this enzyme is limited by enzyme saturation kinetics, which restrict the measurement of clinically relevant glucose concentrations (0 to 25 mM ...
