(a) Time course of antibiotics production of M145 in the culture medium alone or with addition of different concentrations of CuO NPs of 40 nm; (b) Relative abundance of viable bacteria and the ability of producing antibiotics of individual cells treated with different concentration of NPs at 144 h. The left y-axis shows fold changes of viable bacteria of the exposure groups compared to those of control group, which was set as 100%, the right y-axis shows the ability of individual cells to produce antibiotics by the exposure groups compared to that of control group, which was set as one; (c) Time course of antibiotic production of M145 in the culture medium alone or with addition of different sizes of CuO NPs at 10 mg/L concentration.
