Table 1. Calcium (Ca) removed from the treatment solution and bound to bacterial pellet (mean ± sd; n = 4) after 60-min equilibrium with 1 or 10 mM Ca treatments.

Ca concentration	Ca removed from the solution (μmol)	Ca bound to bacterial pellet (μmol)
1 mM	0.29 ± 0.08	0.28 ± 0.09
10 mM	1.90 ± 0.41	1.83 ± 0.26
