FIG. 2.

Maximum salt concentrations suitable for growth (MSCg) of P. halocryophilus expressed as wt% (A), and total molar concentration (sum of cation and anion concentration) (B), and the molar anion concentrations at the corresponding MSCg (C). Transparent parts of the bars represent the salinity range for which neither growth nor complete demise of the culture could be determined within the time of the experiment (see Section 2.2). The water activities and ionic strengths at the MSCg are shown in Fig. S13.
