Scanning electron microscopy (SEM) images of morphological changes in bacteria after they were cultured with pBD2. (a) Control cells incubated without pBD2 for 1 h; (b–d) cells were treated for 1 h with 37.5, 75, and 150 μg/mL pBD2 respectively; (e) control cells incubated without pBD2 for 4 h; (f,g) cells were treated for 4 h with 37.5 and 75 μg/mL pBD2, respectively; (h,i) cells were treated for 4 h with 150 μg/mL pBD2.
