Proteomic analysis of the influence of Cu2+ on the crystal protein production of Bacillus thuringiensis X022

Table 1 LC₅₀ analysis of B. thuringiensis X022 fermentation broth from two different medium

Medium	LC₅₀ (μg/mL) to S. exigua	95 % CI	Slope	LC₅₀ (μg/mL) to H. armigera	95 % CI	Slope
CK^a	1.052	0.692–2.172	0.085	0.518	0.371–0.864	0.075
Cu^b	0.484	0.257–0.544	0.073	0.240	0.146–0.441	0.069

Non-overlapping 95 % confidence intervals of LC₅₀ were used as the criteria to determine significant difference of toxicities among different formulations of acetamiprid
CI confidence interval
^aCK represent fermentation broth from the original medium
^bCu represent fermentation broth from 10⁻⁶ mol/L Cu²⁺ added medium
