n.d.

  1. Cells were cultivated in sealed shake flasks at 30°C on 10 mM of different carbon sources in M9* medium pH 7.0. Errors indicate standard deviations (n = 2 - 5).
  2. n.d.: not determined due to very slow growth (long time experiments result in errors caused by oxygen limitation and/or isobutanol evaporation).
