Exogenous H2O2 does not induce PLY release. a The ∆SpxB mutant of T4R was grown to an OD of 0.5. The bacterial cells treated with 500 μM H2O2 for 1 h and PLY concentrations were quantitated via dot blot. Each figure represents three independent experiments ± SD. b T4R and its ∆spxB mutant were grown to an OD600 of 0.5 and extracellular DNA was quantitated from sterile filtered supernatant by a Qbit fluorometer. Each figure represents three independent experiments ± SD
