Sensitivity of <i>P</i>. <i>putida</i> and <i>P</i>. <i>aeruginosa</i> wild-type and their DNA glycosylase-deficient derivatives to MMS and MNNG.

<p>Sensitivity was estimated by spotting 10-fold dilutions of overnight cultures of <i>P</i>. <i>putida</i> (A, B) and <i>P</i>. <i>aeruginosa</i> (C, D) onto LB plates containing different concentrations of MMS (A, C) and MNNG (B, D). Data represents the mean (±95%CI) values. (●) wild-type; (■) Δ<i>alkA</i>; (▲) Δ<i>alkAtag</i>. <i>P</i>. <i>putida</i> was incubated at 30°C and <i>P</i>. <i>aeruginosa</i> was incubated at 37°C.
