Fig. 1: Representative first derivative of DSC thermograms of Bacillus subtilis cells across Mg(ClO4)2 concentrations.

The first derivative of DSC thermograms of Bacillus subtilis cells during the heating ramp in a water washed cells, c cells exposed to 2 M Mg(ClO4)2, with the location of the vitrification peaks denoted by the black boxes. Panels b and d show representative rescaled thermograms of a and c revealing the vitrification peaks. Panels b and d show the recorded features of the vitrification signal, the Tonset, Tpeak, and Tend.
