Estimate the fraction of plasmid-containing cells in a batch reactor with complex medium if the plasmid-bearing cells have a maximum growth rate of 1.0/hr, the plasmid-free cells grow at 1.35/hr, the batch reactor is operated for 40 hr, the probability of plasmid loss (p) is 0.02, and the inoculum is 100% plasmid-bearing cells. 1000 cells/ml at start.
