Selective, high-yield production of 5-keto-D-gluconate (5KGA) from D-glucose by Gluconobacter was achieved without genetic modification. 5KGA production by Gluconobacter suffers byproduct formation of 2-keto-D-gluconate (2KGA). By controlling the medium pH strictly in a range of pH 3.5-4.0, 5KGA was accumulated with 87% conversion yield from D-glucose. The pH dependency of 5KGA formation appeared to be related to that of gluconate oxidizing activity.
