In batch culture experiments with glycerol and lactate as substrates, hexacyanoferrate (III) was completely reduced. Growth yields increased and the fermentation patterns were shifted towards higher acetate formation with increasing hexacyanoferrate (III) concentrations (0.25- 8.0 raM). In experiments with regulated electrodes, glycerol, lactate, and propionate were oxidized to acetate and CO2, and the electrons were quantitatively transferred to the working electrode. Growth yields of 29.0, 13.4 and 14.2 g cell material per mol were calculated, respectively. The high cell yield obtained during propionate oxidation cannot be explained solely by substrate level phosphorylation indicating that additional energy was conserved via electron transport hosphorylation. Furthermore, this result indicated complete reversibility of the methyl-malonyl-CoA pathway in propionic acid bacteria.</dcterms:abstract> <dc:contributor>Emde, Rainer</dc:contributor> <dc:creator>Schink, Bernhard</dc:creator> <dc:creator>Emde, Rainer</dc:creator> </rdf:Description> </rdf:RDF>
