Fig. 4From: Proteomic analysis of the influence of Cu2+ on the crystal protein production of Bacillus thuringiensis X022Dose-dependent mortality assays of B. thuringiensis X022 toxicity to a S. exigua and b H. armigera. CK: fermentation broth from the original medium; Cu: fermentation broth from the medium to which 10−6 mol/L Cu2+ had been added. Each point represents the mean and standard deviation of three independent experimentsBack to article page
