Our investigations have led to the development of a rapid and efficient process for the production of 5-ketogluconic acid from glucose by Acetobacter suboxydans, as heretofore reported (Stubbs et al., 1940). However, we have not found it possible to conduct a fermentation with our strain of A. suboxydans on any substrate in such a manner that 2-ketogluconic acid is the major product, as has been reported by Bernhauer and Knobloch (1938). These authors found that a certain strain of A. suboxdans gave predominantly 2-ketogluconic acid when cultivated on gluconic acid salts, although when cultivated on
