The effect of oxygen limitation on the stability of a recombinant yeast plasmid was measured during continuous culture in a non-selective medium. The fraction of plasmid containing cells was found to decrease more rapidly after a step change to low dissolved oxygen (DOT) levels. An increased rate of plasmid loss appeared to be the major cause of the decreased stability.
