Figure 1From: Polymyxin P is the active principle in suppressing phytopathogenic Erwinia spp. by the biocontrol rhizobacterium Paenibacillus polymyxa M-1In vitro antagonistic effect of P. polymyxa M-1 against E. amylovora Ea273 and E. carotovora. (A) Inhibiting effect of M-1 culture supernatant (CS) against E. amylovora Ea273. (B) Inhibiting effect of M-1 culture supernatant against E. carotovora. “M-1CS” represents M-1 GSC culture supernatant. GSC medium was used as a negative control. M-1 cells were also spotted onto lawns of E. amylovora Ea273 and E. carotovora. E. coli DH5α cells were used as a negative control.Back to article page
