Figure 4

Variation of the plasmid copy number during the cultivations of L. plantarum overexpressing β-galactosidase from L. reuteri. L. plantarum WCFS1 harbouring the pEH9R plasmid was cultivated in 400-ml laboratory fermentors at 37°C using MRS medium with 40 g/l glucose, pH control at pH 6.5 and the cells were induced at OD ~ 3 with 80 ng/ml peptide pheromone. All data points represent the average value from 2 independent experiments.
