Eighteen strains of Escherichia coli used in genetic studies were tested for their ability to grow on several selective media. Highest recoveries were obtained with m-T7 agar. The SOS system, particularly the recA gene, may play some role in the sensitivity of E. coli to selective agents. These results may be important in the selection of media used to detect genetically engineered organisms released into the environment.
