The stabilities of plasmid vectors in Zymomonas mobilis were tested in batch and continuous cultures. It was found that the growth of the host Zymomonas strain was greatly affected by the size of plasmids as well as the composition of nutrient media: the host cells grew taster when harboring plasmids of smaller sizes and in n non-selective medium. All the Zymomonas plasmid vectors containing antibiotics selective markers and Zymomonas replication origins could be maintained in a stable manner over 30 generations without being integrated into host chromosomes.
