Abstract
Continuous culture fermentation of Pseudomonas putida PPK1, containing the naturally occurring TOL plasmid pTK0, was carried out in either b enzoate- or succinate-limited chemostats. The apparent stability of th e plasmid decreased with increasing the dilution rate. An established model was used to predict the contribution of segregational instabilit y and growth rate difference to the apparent plasmid stability.
