Toxicity of the PtC1015 clone on the G. mellonella larvae: (A) Mortality caused by the whole cells (1 × 103 CFU), and supernatant (1 μg) injection. Whole cells or supernatant of E. coli XL1-Blue MRF` were used as the control. ●, whole cell of PtC1015 clone; ■, whole cell of E. coli XL1-Blue MRF`; ○, supernatant from PtC1015 clone; □, supernatant from E. coli XL1-Blue MRF`; (B) Mortality caused by injection of soluble and insoluble protein fraction (10 μg each). The protein fractions prepared from the E. coli XL1-Blue MRF` were used as the control. ●, soluble fraction of PtC1015 clone; ■, soluble fraction of E. coli XL1-Blue MRF`; ○, insoluble fraction of PtC1015 clone; □, soluble fraction of E. coli XL1-Blue MRF`. All experiments were repeated at least three times and presented with standard deviation. Some error bars (standard deviation) are smaller than the symbols.
