Gluconobacter oxydans is unsurpassed by other organisms in its ability to incompletely oxidize a great variety of carbohydrates, alcohols and related compounds. Furthermore, the organism is used for several biotechnological processes, such as vitamin C production. To further our understanding of its overall metabolism, we sequenced the complete genome of G. oxydans 621H. The chromosome consists of 2,702,173 base pairs and contains 2,432 open reading frames. In addition, five plasmids were identified that comprised 232 open reading frames. The sequence data can be used for metabolic reconstruction of the pathways leading to industrially important products derived from sugars and alcohols. Although the respiratory chain of G. oxydans was found to be rather simple, the organism contains many membrane-bound dehydrogenases that are critical for the incomplete oxidation of biotechnologically important substrates. Moreover, the genome project revealed the unique biochemistry of G. oxydans with respect to the process of incomplete oxidation.
