| Abstract | The capacity to produce an aldonic acid from aldose sugars is widespread among acinetobacters. The enzyme responsible for this reaction is a membrane-bound, pyrrolo-quinoline quinone (PQQ)-dependent aldose dehydrogenase (E.C. 1.1.99.17). Fermentor studies with Acinetobacter calcoaceticus strain LMD 79.41 showed that the aldose dehydrogenase is synthesized constitutively. Preliminary results obtained with carbon-limited chemostat cultures of this organism revealed that the cell yield on mixtures of acetate and glucose was significantly higher than on acetate alone (molar growth yield (g multiplied by mole super(-1)) for acetate 14.6 versus 21.3 for acetate plus glucose). Since glucose is almost quantitatively oxidized to gluconic acid it follows that the aldose dehydrogenase may play a role in energy metabolism of acinetobacters. |
