PQQ AND Glycolysis

The obligatory aerobic acetic acid bacterium Gluconobacter oxydans incompletely oxidizes carbon sources regio- and stereoselectively in the periplasm and therefore is used industrially for oxidative biotransformations, e. g., in vitamin C production. However, it has a very low biomass yield as the oxidized products largely remain in the medium and cannot be used for anabolism. Cytoplasmic carbon metabolism occurs via the pentose phosphate pathway and the Entner-Doudoroff pathway, whereas glycolysis and the tricarboxylic acid cycle are incomplete...
