Figure 1

Variation of the pH and soluble silicon concentration of the bacterial cultures at different sampling points (Experiment 1): (a) the pH value at three sampling points; and (b) the concentration of soluble silicon at three sampling points.

Bacteria were cultured in a medium with CaCl2 and wollastonite as calcium sources (gray bar) or with wollastonite only (black bar). *The results from the two treatments are significantly different (p = 0.033).
