Characterization of the motility of bacteria in DSCG solutions. (A) Bacterial speed and (B) standard deviation of the orientation of the bacterial body as a function of the DSCG concentration. The standard deviation (SD) was used as the error bars. All experiments were made at 22.5 ± 0.5°C. The number of data acquired for each concentration is shown in Table S3 (1808 individual bacteria in total, and more than 83,500 positions). The gray hatched zone represents the DSCG concentration range where both phases coexist (isotropic and anisotropic). The gradient shaded zone represents the DSCG concentration range where the pretransition phenomena are observed (see main text for details). To see this figure in color, go online.
