Participants

Reaction Steps

The reaction mixture containing 400 ml of purified membrane-bound L-sorbose dehydrogenase (total activity, 120 units), as prepared by the manner as described in steps (1) to (5) of Example 1, 50 ml of 0.5M potassium phosphate buffer (pH 6.0). 50 ml of 1M L-sorbose solution and 10 ml of 0.2M phenazine methosulfate solution was incubated at 30° C. with gentle shaking. As a result, L-sorbosone was formed with the rate of 224 mg/hr.
