Structural specificity requirement of a substrate in aldose oxidation by Acetobacter suboxydans was examined with intact cells. Among the various aldoses tested, D-xylose, D-glucose, D-gulose, and D-glycero-D-gulo-heptose were oxidized to the corresponding aldonic acids. It was found that in the oxidation of D-glucose, D-gluco-pyranose is first oxidized to D-glucono-δ-lactone which is then hydrolyzed to D-gluconic acid. Considering the structural requirement for aldose oxidation of this bacteria, with reference to the pyranose structure, it is found that the rule of cyclitol oxidation is not applicable and that the C-1 hydroxyl is oxidized when the C-3 and C-4 positions bear equatorial-equatorial or axial-axial hydroxyls, and there are no axial-equatorial or equatorial-axial hydroxyls in C-2 and C-5 positions.
