Figure 4

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