Thymineless death in a thymine-dependent mutant of Micrococcus radiodurans T2 in the presence of chloramphenicol and rifampicin

A possibility to prevent cells of a thymine-dependent mutant of Micrococcus radiodurans T2 from thymineless death was investigated. It was found that the presence of chloramphenicol (CAP) in a thymineless medium only decelerated the death of cells. The presence of rifampicin (RFP) considerably decreased the death rate of cells but could not prevent thymineless death completely.
