Effect of some redox mediators on FAD fluorescence of glucose oxidase from Penicillium adametzii LF F-2044.1.

Glucose oxidase (GOx) of Penicillium adametzii LF F-2044.1 recovered by ultrafiltration, was characterized by spectrophotometric and spectrofluorometric methods. It was shown that spectra of GOx from P.

Comparison of glucose oxidases from Penicillium adametzii, Penicillium Funiculosum and Aspergillus Niger in the design of amperometric glucose biosensors.

The properties of amperometric glucose biosensors based on three different glucose oxidases and various redox mediators were evaluated. Glucose oxidases (GOx) from Penicillium adametzii, Penicillium funiculosum and Aspergillus niger and artificial redox mediators, such as ferrocene, ferrocenecarboxaldehyde, α-methylferrocene methanol and ferrocenecarboxylic acid, were used for modifying the graphite rod electrode and amperometrical reagent-less glucose detection. The obtained results were compared using N-methylphenazonium methyl sulphate in the solution.

Specificity of glucose oxidase from Penicillium funiculosum 46.1 towards some redox mediators.

Glucose oxidase (GOx) from Penicillium funiculosum 46.1 was purified using step-by-step ultrafiltration and it was characterized by spectrophotometric and spectrofluorometric methods. It was shown that spectra of GOx produced by P.
