Membrane-bound dehydrogenases of Gluconobacter oxydans : Sensors for measuring sugars, alcohols, and polyoles

The activity of membrane-bound dehydrogenases of immobilized Gluconobacter oxydans was used in ampero- and potentiometric biosensors for measuring glucose, ethanol, and glycerol. An amperometric biosensor was used for detection of glucose in human blood, glycerol in fermentation media, and ethanol vapors in the air. The results indicate that biosensors for practical use in medicine and biotechnology can be created on the basis of this cells culture.
