Continuous production of glucose-6-phosphate by immobilized Achromobacter butyri cells
- 23 Downloads
Whole cells of Achromobacter butyri OUT 8004 having polyphosphate glucokinase activity were immobilized in polyacrylamide gel. The immobilized cells were activated by organic solvents, especially acetone. The immobilization resulted in increased stability of polyphosphate glucokinase. Continuous high yield production of G-6-P from glucose and metaphosphate was performed with an immobilized cell column, which had a half-life of approximately 20 days.
