Figure 8

Improved intracellular ectoine content in E. coli DH5α pAKECT1. Intracellular ectoine concentrations of the new recombinant ectoine producer E. coli DH5α pAKECT1 with (white bars) and without (grey bars) IPTG-induction of the feedback-insensitive aspartate kinase at salinities between 1% and 5% NaCl in minimal medium MM63. For sake of comparison the data obtained with the control strain E. coli DH5α pHSG575, supplemented with 2 mM ectoine in the growth medium, are added to the graph as a solid line. Mean values and standard deviations are based on three independent experiments.
