Kinetics of lysogen induction. MG1655 lysogenized with 933W (▲), BAA2326 (■), λ (♦) and 434 (▼) were grown to mid-log phase at 37 °C. The resident prophages were induced by (a) adding mitomycin C, or (b) irradiating with UV light, as described in Materials and Methods. For samples induced with mitomycin C, the amount of phage (plaque forming units—PFU) and bacteria (colony forming units—CFU) were determined at the indicated times after addition of the agent. For samples induced with UV, samples were irradiated for the indicated time and the amount of PFU and bacteria CFU were determined after 2 h of additional growth. Error bars represent ±standard deviation.
