Fluorescence values arose from the CadC-GFP associated with P cad O cad after incubation with Cd (II)-added milk (A and B) and yoghurt (D and E) measured by fluororeader (A and D) and fluorometer (B and E). Absorbance values of ET-AAS obtained with Cd (II)-added milk (C) and yoghurt (F). A solid line and two broken lines show mean ± SD of data obtained with milk or yoghurt without addition of Cd (II). Asterisk means statistical significance versus the milk or yoghurt without addition of Cd (II) (*P < 0.05, **P < 0.01, ***P < 0.001).
