Growth profile of IMI078 (Pdc^-MTH1-ΔT ) on glucose as the sole carbon source. Cultivation in an aerated pH-controlled (pH 5) bioreactor growing on 7.5 g l^-1 glucose without external C₂-sources. The depicted results are from one experiment of a set of four replicates, which all had identical specific growth rates (0.097 ± 0.007 h^-1). The lag phase (rCO₂ > 1 mmol l^-1 h^-1) of the replicates varied between 20 and 80 h after inoculation.
