abstract：:After UV irradiation, Escherichia coli uvrA mutant cells show higher survival on minimal than on rich growth medium, i.e., they show minimal-medium recovery. This effect of rich growth medium on survival is not observed in a uvrA mutant carrying an mmrA1 mutation, and the uvrA mmrA strain showed the same survival rate...

This inhibition was bacteriocidal rather than bacteriostatic and was not caused by a bacteriophage. Whereas the bacteriocin was inactive on the 7 Serratia strains tested, it killed 11 of the...
