Extracellular metabolites obtained by 1H-NMR measurement (red: exponential growth and black: stationary growth). 1) fumarate, 2) glucose, 3) malate, 4) succinate, 5) 2-oxoglutarate, 6) pyruvate, 7) unknown, 8) isovaleric acid, 9) acetate, 10) 2-amino-isobutyrci acid, 11) ethanol (could be a contamination), 12) unknown, 13) isobutyric acid, 14) 2-methylbutyric acid. Further small amounts of e.g. butandiol, acetoine, valine and leucine could be detected at some time points during cell growth.
