Figure 5. Quantification of bacteria of the genus Bacillus by the amount of CaDPA released upon thermal treatment.

Vertical and horizontal error bars indicate uncertainties in spore counting and CaDPA quantification (sd, N = 3). The concentration of spores is in the log scale for clarity. [Bn] = 5.8 µmol L^–1, [EuCl₃] = 17.4 µmol L^–1 (3 equiv) in MOPS buffer pH = 7.5.
