Cell-associated metal ion concentrations (expressed ug g−1) of S. pneumoniae D39 wild-type when grown in CDM with either 0 mM or 0.5 mM Ni2+. The statistical significance of the differences in the mean metal ion concentrations was determined by One-way ANOVA (NS not significant, *P < 0.05, and **P < 0.001).
