Stability and Catalytic Properties of Glucose Oxidase from Penicillium
Funiculosum g-15
Abstract
Glucose oxidase was extracted from a newly isolated strain Penicillium
funiculosum G-15. The enzyme is stable to metal ions except Cu2+and
Zn2+ at 25°C and pH 6,0. It is
highly specific for D-glucose (Km 3.3 mM) and keeps the optimal
activity in the wide range of temperatures and pH values.Mediator activity of
ruthenium complexes in the catalysis of GO from P. funiculosum G-15 were
compared with this activity relative to the enzyme from Aspergillus niger.
