Inhibition of bacterial growth by molting fluids. Each type of molting fluid was incubated separately with fresh B. subtilis (A) or E. coli (B) for 2 or 4 h, respectively. Bacterial colonies were then counted after culture on LB plates at 37 °C for 12 h. Bars represent the mean of independent measurements ± S.E. (error bars) (n = 5 (A) and n = 4 (B)). *, p < 0.05; **, p < 0.0001.
