Chloramphenicol-promoted increase in resistance to UV damage in Escherichia coli B/r WP2 trpE65: development of the capacity for successful repair of otherwise mutagenic or lethal lesions in DNA.

Abstract excerpt

The ultraviolet radiation survival curve of exponentially growing cultures of Escherichia coli B/r WP2 trpE65 was modified by a short period (20 min) of chloramphenicol treatment before UV exposure, which produced an extended exponential section of intermediate slope between the shoulder and the final exponential slope. More prolonged incubation with chloramphenicol (up to 90 min) resulted in little further...
