Lysogeny NotesOrkz demonstrates temperate behavior. Lysogenic colonies were successfully isolated from phage-seeded plates and maintained on PYCa plates. When the lysogens were streaked onto lawns of A.g bacteria, clearing zones were observed due to spontaneous phage release and subsequent lysis of the host bacteria.
