Survival fraction of E. coli AB1157, AB1157+pBW21, BW527, and BW527 + pBW21 treated with SnC l 2 . Mid-log phase cells suspended in 0.9% NaCl were treated with 25  𝜇 g/mL SnC l 2 for different incubation times and the specific survival fraction. Survival fraction values are means ± standard deviations of the three isolated experiments.
